The Link River Dam is a concrete dam on the Link River in the city of Klamath Falls, Oregon. It was built in 1921 by the California Oregon Power Co. The dam was built to control the water level of Klamath Lake in order to maximize power production. Water stored behind the dam also supplies most of the water used for irrigation in the Klamath Reclamation Project.
The Link River Dam diverts water to two hydroelectric power plants located downstream. The two turbines are part of a group of seven projects, supplying 151 MW for PacifiCorp. PacifiCorp recently announced the Link River power projects will be abandoned as the cost to repair the canal and pipeline supplying the power turbines is too high to be economically viable.
The dam itself is 22 feet (7 m) high and 435 feet (133 m) long. It can allow an outflow of 3,000ft³/s (85 m³/s) with 1,000ft³/s (28 m³/s) through the Ankeny Canal (seen in the photograph), 290ft³/s (8 m³/s) through the Keno Canal, and the rest being dumped down the Link River into Lake Ewauna. The two canals serve PacifiCorp's hydroelectric turbines before flowing back into the river.
The Link River is a short river connecting Upper Klamath Lake to Lake Ewauna in the city of Klamath Falls in the U.S. state of Oregon. Draining a basin of 3,810 square miles (9,900km2), the river begins at the southern end of Klamath Lake and flows a short distance to the Link River Dam and continues 1.5 miles (2.4km) to the head of Lake Ewauna. The "falls" from which Klamath Falls derives its name, and which in reality are best described as rapids rather than falls, are visible a short distance below the dam, though the water flow is generally insufficient to provide water flow over the rocks. The Klamath River begins at the narrow southern end of Lake Ewauna and flows 253 miles (407km) from there to the Pacific Ocean.
Before settlers came to the Klamath Basin, the Link River was known to the local Klamaths as Yulalona, meaning "back and forth." At times, strong winds blew the water upstream into Klamath Lake and partly drained the riverbed.
After its founding in 1867, Klamath Falls was originally named Linkville. The name was changed to Klamath Falls in 1892–93.

The hydroelectric plant will be an energy storage facility with a turnaround efficiency of 78.9 per cent that utilises the water stored in the upper dam, which is converted to kinetic energy during the flow of water through a 1.2 km subterranean tunnel.
This kinetic energy rotates the turbines and converts mechanical energy to electrical energy which is sent to DEWA’s grid within 90 seconds in response to demand.
To store energy, clean energy generated at the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump the water through this tunnel back to the upper dam by converting the electrical power to kinetic energy, making the whole project 100 per cent renewable.
“The hydroelectric power plant in Hatta is part of the projects and initiatives launched by DEWA to diversify energy production from renewable and clean sources in Dubai. These include different technologies such as solar photovoltaic panels, concentrated solar power, and green hydrogen production using renewable energy,” explained Saeed Mohammed Al Tayer, MD & CEO of DEWA.


China, Pakistan and Tajikistan have been named the biggest producers of new hydropower in Asia in 2019
China, Pakistan and Tajikistan have been identified as the biggest producers of new hydropower in the Asian region in 2019. Carrieann Stocks takes a look at what developments are currently underway in each country that will further add to its installed capacity over the next few years.
New installed hydropower capacity in the East Asia and Pacific and South and Central Asia reached 13,131MW in 2019, according to the International Hydropower Association’s (IHA) Hydropower Status Report, with much of this new potential coming from China (8540MW), followed by Pakistan (2487MW), and Tajikistan (605MW).
This new potential brought each countries existing potential to: 352,260MW in China; 9827MW in Pakistan; and 5795MW in Tajikistan.
Hydropower in China
One of the biggest projects China is currently working on is the 16,000MW Baihetan project. The hydropower station is designed to have 16 domestically-manufactured generating units each with a 1GW capacity. It will be the second largest hydropower station after the Three Gorges project in terms of total installed capacity.
Under construction on the Jinsha River, a tributary of the Yangtze River in south-west China, the project extends over the Ningnan county in the Sichuan province and the Qiaojia county in the Yunnan province. It is scheduled for commissioning in 2022.
Baihetan is being developed by Jinsha River Chuanyun Hydropower Development Company, a joint venture between China Three Gorges (CTG) Corporation (70%), Sichuan Energy Investment Group (15%), and Yunnan Energy Investment Group (15%).
Baihetan and another project currently under construction upstream – the 10.2GW Wudongde project – was envisioned under the Go-West Program of China, which is aimed at transferring electricity from west to east China.
The Baihetan project includes the construction of a concrete double-curvature arch dam with a maximum dam height of 289m. The dam crest elevation is 834m and centre line arc length is 709m. The Baihetan dam will have six flood gate structures and three spillway tunnels.
The project will have two underground powerhouses, one each on the left and right banks of the dam.
China Three Gorges (CTG) is responsible for the construction of the Baihetan hydropower project. CTG collaborated with local power equipment researchers and manufacturing company Dongfang Electric Machinery to develop the first 1000MW turbine generator for the project.
HBIS Wusteel, another Chinese company, supplied material for the turbine stay rings, generator lid, and control rings. Dongfang Electric Machinery is responsible for supplying eight turbine generator units for the left bank power house, while Harbin Electric Machinery Factory will provide the remaining eight units for the right bank power house.
Caterpillar supplied machinery for the earth works at the Baihetan hydropower project.
The Wudongde project, along with Baihaten, forms the second phase of the four large hydropower projects being constructed downstream of the Jinsha River. The first phase involved the construction of the Xiluodu Hydropower Station and the Xiangjiaba Hydropower Station.
On completion of Phase 2, the four hydropower plants will have a combined installed capacity of 46,460MW and an annual electrical output of 190TWh.
Wudongde primarily involves the construction of an approximately 300m-high double-curvature retaining arch dam, flood discharge structures, and water intake and power generation facilities.
The underground power houses, located on both banks of the dam, will be equipped with six Francis turbine units each. The capacity of each turbine generator is rated at 850MW.
Progress on Wugongde is reportedly going very smoothly with the dam expected to start storing water in July 2020, The first generator will be placed into operation in August 2020, with all units expected online by December 2021. Voith and GE were awarded contracts to supply equipment to the project, with each supplying six turbines.
Pumped storage development
Another major project under development is the 3.6GW Fengning pumped storage plant in the Hebei Province – expected to be the largest scheme of its kind once complete.
Fengning will be built in two phases, each featuring six reversible pump turbine units with a capacity of 300MW each. In the second phase two of the six units will be variable-speed motor-generator units.
Designed for balancing the intermittent renewable energy resources of large Mongolian wind and solar parks, Fengning 2 will be connected to the Beijing-Tianjin-North Hebei grid with two 500 kV lines. The designed annual power generation will be 3.424 TWh with 4.565 TWh of corresponding pumped water meeting peak power needs.
Securing safe and stable grid operation, and increasing power supply quality, the installation will boost local employment, promote tourism and farming industries. In addition, Fengning will contribute to emissions reduction and have significant positive social, ecological, and economic perks.
In 2017, Andritz Hydro received a contract from the state-owned Chinese energy utility company Fengning Pump Storage Co. Ltd. and State Grid Xinyuan Co. Ltd. to supply two variable speed generators for the project. The units will have a nominal capacity of 330 Mega Volt Amperes (MVA) in generator mode and 345 MVA in pump mode. Additionally, AC-excitation, governors, as well as protection and computer control systems are part of the contractual scope.
The first phase of the project is scheduled to come online prior to the start of the 2022 Winter Olympics, with the second phase to be completed in 2023.
Developments in Pakistan
There are a number of big projects currently in construction in Pakistan. Among these are the 800MW Mohmand dam project which started construction last year, the Tarbela 5th Extension project which will increase the Tarbela Power Plant’s total generating capacity from 4888MW to 6300MW, and the 4320MW Dasu and 4500MW Diamer-Basha projects, both of which are due to start construction this year.
Mohmand Dam project is being constructed on the River Swat in the Tribal district Mohmand of Khyber Pakhtunkhwa province. It is a multi-purpose project with gross water storage capacity of 1.2 million acre feet and power generation capacity of 800MW.
Water and Power Development Authority (WAPDA) of Pakistan is the implementing authority of the project. The Mohmand dam was proposed in the early-2000s, but work related to the project was started in 2017 upon completion of detailed engineering and design.
The hydropower project was approved in March 2019 with an estimated investment of PKR309 billion ($2.17 billion). The groundbreaking ceremony of the project was held in May 2019, while commissioning is scheduled for July 2024.
The Mohmand hydropower project will include a 213m-high concrete-faced rock-filled dam and two 3317m-long low-level river diversion outlets with a diameter of 15m. The dam will feature seven radial gates with a width of 15m and height of 21m.
A joint venture of China Gezhouba group (CGGC) and Descon Engineering was awarded the engineering, procurement, and construction contract by WAPDA.
The contract includes the construction of access roads, irrigation facilities, dam and ancillary works, as well as design and installation of electromechanical equipment and hydraulic metal structures.
At the end of November 2019, WAPDA has announced that it has signed a contract worth US$734 million with a joint venture of GE Hydro China and Power China Zhongnan Engineering Corporation for electro-mechanical works of Dasu Hydropower Project (Stage-I).
The contract includes design, supply and installation of six Francis turbines, generators, main transformers, generator and station service switchgear along with related equipment.
The 4320MW Dasu project is being constructed by WAPDA on the River Indus, upstream of Dasu Town in Kohistan District of Khyber Pakhtunkhwa Province.
The project will be completed in two stages – each stage having a generation capacity of 2160MW. At present, Stage-I of the project is underway, with electricity generation from the project is expected to commence in 2024-25. Stage-I will contribute more than 12 billion units per annum to the National Grid. Stage-II will also provide another 9 billion units to the system every year.
The World Bank is partially providing funds for construction of Stage-I to the tune of US$588.4 million and Partial Credit Guarantee (PCG) of $460 million. The remaining funds are being arranged by WAPDA from its own resources and with the sovereign guarantee of Government of Pakistan.
In Early December 2019, WAPDA said it is all set to commence construction work on Diamer Basha Dam following award of contract in early 2020. Preliminary works have started at the project, which is located on the Indus River.
Hydropower in Tajikistan
A major project underway in Tajikistan is the 3600MW Rogun dam project. The project is already partially operating with the plants 2nd unit launched in September 2019, 10 months after the first unit was launched in November 2018.
Rogun is being constructed on the upper reaches of the Vakhsh River in the Pamir mountain ranges. The hydroelectric dam will have a crest elevation of 1300m asl and measure 335m high, which will make it the world’s tallest dam once complete.
Rogun will be a rockfill dam with a clay core, with a foundation level of 965masl, a crest length of 660m, and a crest width of 20m.
The hydropower plant will be equipped with six radiaxial hydraulic turbines with a capacity of 600MW each. The powerhouse will be approximately 21m-wide, 69m-high and 220m-long and will be situated in a cavern constructed of sandstone and siltstone.
Salini Impregilo signed a framework agreement with OJSC Rogun HPP to serve as the engineering, procurement and construction (EPC) contractor for the project.
Salut Industrial Engineering Group has been contracted to manufacture and supply the specialised equipment, tanks and vessels for the water-turbine lubricating systems.
Work started last summer on another major project in the country, a climate adaptation project at the Qairokkum hydropower plant. The project, which will see a full rehabilitation at the plant, will increase its installed capacity from 126MW to 174MW.
The upgrade will introduce innovative climate resilience measures, enabling the plant to cope with the expected impact of climate change on the country’s hydrological systems.
It will also build the capacity of the Tajik hydropower operator to anticipate, assess and manage climate-related risks by introducing best international practices from countries such as Canada.
The work is the culmination of an investment programme that began in 2014, with financing provided by the European Bank for Reconstruction and Development (EBRD), the European Investment Bank (EIB), the Green Climate Fund (GCF), the Climate Investment Funds’ Pilot Programme for Climate Resilience, Austria and the United Kingdom. The government of Austria is also funding technical cooperation support.
The financing, comprising a $88 million EBRD loan, a $37 million EIB loan, a $50 million GCF loan and grant and a $21 million Climate Investment Funds loan and grant to the state-owned power utility Barki Tojik, will fund the rehabilitation and modernisation of the 60-year-old hydropower plant that provides electricity to 500,000 people.
Measures also include concrete dam works and the installation of hydraulic steel components, turbines and electromechanical equipment for the six hydropower units.

The Lunersee Hydroelectric Power Project will aid in power production and dissemination to both Austria and West Germany.
The Lunersee Hydroelectric Project is one of two large hydroelectric projects approved for Austria in 1955, both aiming to supply neighboring countries, in this case West Germany, as well as the domestic market. The project will produce winter peak power from pumped storage. It will consist of the construction of a small dam across the lower end of Luner Lake (Lunersee) to increase its storage capacity, divert the run-off of a glacier into the lake, and construct 9.7 kilometers of tunnels, siphons, and penstocks to convey water from the lake to a new power house in which generating and pumping units will be installed. The Austrian benefits will include additional power facilities to satisfy demands in Vorarlberg and Tirol. The German benefits include the availability of additional power during peak demand and the sale of off-peak energy to the project for pumping.
The profile contains project and financial information and lists of project documents and archival records.

East Ascension Parish Consolidated Gravity Drainage District Marvin Braud Drainage Pump Station Expansion
BKI was selected by the East Ascension Parish Consolidated Gravity Drainage District for the expansion of the 5000 CFS Marvin Braud Pumping Station.
The 2000 CFS expansion included bays for two vertical 1000 CFS “flowerpot” design pumps with USACE Type 10 formed suction inlet intake. The pumps are each driven by 2250 horsepower diesel engines through one parallel and one right angle gear, with both engine and gear being liquid cooled through submerged keel type heat exchangers.
Additional mechanical systems include climber type bar screen cleaners; diesel and electrical air compressor and air tanks to provide engine starting air; numerous ventilation fans and louvers to remove engine heat; and three 15,000 fuel tanks, piping, and accessories.
The local soil capacity allowed the station's reinforced concrete foundation to be constructed without the use of piles. Station intake wings were constructed with steel sheet piles, while the intake bays, exterior and interior below water walls and operating slab are concrete to provide a solid foundation for the machinery. The main operating area is contained within a pre-manufactured steel superstructure supported by BKI-engineered steel framing. An elevated safe room designed to provide large missile and high wind protection is attached and includes full kitchen and bathroom areas to allow potential prolonged residence.
All structural components are design to IBC standards, applying calculated wind loads forces. The safe room also incorporates certain Miami-Dade design elements.
West Jefferson Levee District Cousins Drainage Pump Station Expansion
BKI was contracted by the West Jefferson Levee District to design improvements to the Cousins Drainage Pump Station Complex.
BKI completed two projects at the complex. First, we designed an additional 2,000 CFS of pumping capacity by adding a new pumping station with a pile-supported intake basin and concrete discharge tubes, a steel-framed superstructure, and two 1,000 CFS horizontal pumps with diesel engine drives. The project required relocating existing fuel tanks and rerouting fuel lines to maintain flow to the existing pump station during construction.
BKI also designed the construction of reinforced concrete floodwalls along the banks of the Cousins discharge channel downstream from the Cousins Pump Station.
To facilitate installation of the channel’s float-in, prefabricated concrete culvert, a 36-inch water line was relocated over new floodwalls that extended from the culvert walls. The new floodwalls, discharge channel improvements, and culvert provide continuous hurricane protection along the discharge channel until the canal flow discharges into the Harvey Canal.
Additionally, BKI provided engineering support services to ensure that improvements were made according to the plans and specifications.
The construction cost for both projects was approximately $22.8 million.
I-10 / I-610 Interchange: Railroad Underpass Pump Station
BKI was selected by the Louisiana Department of Transportation and Development to prepare the preliminary and final plans for the construction of a new 850 CFS drainage pumping station designed to reduce flooding on Interstate 10 in New Orleans.
The new pumping station was designed to keep the interstate from flooding during a 100-year flood event.
The pumping station consisted of three 72-inch vertical pumps and one 48-inch vertical pump. Flood waters were pumped over land through four steel pipes and across the levee into the 17th Street Canal.
In order to collect the storm water and transport it to the pumping station, the existing subsurface drainage system was replaced with a new collection system. The new drainage system is made up of 2,000 linear feet of 84-inch concrete pipe and various trench drains and catch basins to intercept the storm water, as well as a new 1,200-foot-long intake canal consisting of two 8.5-foot-by-10-foot concrete box culverts.
The approximate total construction cost was more than $18 million.

OMAHA, Neb. -- Water releases from Fort Randall Dam at Pickstown, South Dakota and Gavins Point Dam near Yankton, South Dakota are being increased this week in support of the 2017 navigation season downstream. At Gavins Point, releases will be increased 3,000 cfs per day until they reach navigation support levels, which are estimated at 25,000 to 28,000 cfs this spring. Fort Randall’s releases will be used to back up the Gavins Point releases and are typically 2,000 to 3,000 cfs lower than Gavins Point.
Due to scheduled maintenance, water releases are currently limited to 20,000 cfs though the powerhouse at both Fort Randall and Gavins Point. At Fort Randall, flows above that level will be released through the outlet works. Buoys have been placed below the outlet works to protect boaters from the extra turbulence caused by water releases from the outlet structure. Boats are not allowed upstream of the cabled buoy line. At Gavins Point, flows above 20,000 cfs will be released through the spillway.
Scheduled maintenance at both projects will continue through mid-April.

By Belina Thapa, Lamjung, Mar 30: Construction works of all hydropower projects in Lamjung district have been halted for the last several days.
Altogether nine large and small hydropower projects are under construction in Lamjung with total installed capacity of 202.17 MW.
Works of those hydropower projects have been shut down after the enforcement of lockdown to control the spread of coronavirus (COVID-19) in the country.
Workers involved in these projects are now in difficulty due to the shutdown of projects. They are living in a camp after the closure of construction works.
According to projects, supply of construction raw materials has been obstructed due to the lockdown.
Construction works of 54 MW Super Dordikhola Hydropower Project ‘B’, 25 MW Upper ‘A’, 12 MW Dordi-1 and 27 MW Dordikola Hydropower Projects based on Dordi Khola of Dordi Gaunpalika have been completely halted for the last seven days.
Similarly, construction of 4 MW Upper Chhandikhola Hydropower Project based on Chhandikhola and 30 MW Nyadi Hydropower Project and 40.27 MW Upper Nyandi Hydropower Project based on Nyadikhola have also been disturbed due to the lockdown.
Likewise, according to local people, construction works of 2.4 MW Upper Syange, 7.7 MW Midimkhola hydropower projects have also been obstructed.
Director of 25 MW Upper Dordi ‘A’ Project Rajendra Wosti said that the construction of the project had been halted when the works were about to end.
He said that construction works had been disturbed when 97 per cent works had completed and it was targeted to open by mid-April, 2020.

Amaila Falls Dam Profile
Capacity: 165 MW
Flooded Area: 23 Km2
Cost: US$ 840.3 million
Operational Status: Planned
Companies Involved: China Railway First Group (CRFG)
Funders Involved: China Development Bank (CDB) / The Inter-American Development Bank (IADB)
The Amaila Hydropower Project involves the construction of a hydropower plant in the area of west-central Guyana, where the Amaila and Kuribrong rivers meet. Electricity produced at the plant will be delivered to Guyana’s capital, Georgetown, and its second largest town, Linden, by an electric transmission line. Construction of the plant was scheduled to begin in late 2011. It is projected to take approximately four years to complete.
There are three parts to the Project:
Hydropower Plant. Construction of a dam where the Amaila and Kuribrong rivers meet will create a reservoir upstream of the dam. The Amaila storage dam site would be located near the top of Amaila Falls and would impound the waters of both the Kuribrong and Amaila Rivers. The project is expected to have the capacity to produce 165 MW of electricity by releasing impounded water through turbines specifically designed and built for the plan.
The flooded area of the reservoir would be approximately 8.8 square miles at full supply level of 1,400 feet and is heavily forested. The reservoir would be cleared for one-half mile upstream of the dam.
Transmission Lines. Electricity will be delivered from the hydropower plant to Georgetown and Linden through a high-voltage 230-kV transmission line that will be built along with electric substations in Linden and Georgetown. The 270 km long transmission line will be supported on towers approximately 36 m tall and 300 m apart, carrying two circuits thus providing redundancy in the event of loss of one circuit.
Access Road. In order to access the Project site, new roads will be constructed and some existing roads will be upgraded. A new road approximately 65 km long will be built connecting the project site to the existing Bartica-Potaro Road. Another new road approximately 20 km will be constructed from the existing Mabura Hills Highway to the Essequibo River. Other existing roads will be upgraded in order to provide access needed to move the equipment, supplies, and personnel to build the Project, as well as for future operation and maintenance of the plant and transmission lines. Construction of access roads began in 2010 and will be completed in advance of the construction of the Hydropower Facility.

Clarrie Hall Dam Reopened
Council's $7.3 million upgrade of Clarrie Hall Dam was unveiled on 22 May 2014 by the NSW Minister for Natural Resources, Lands and Water, the Hon. Kevin Humphries, MP.
By widening and extending the spillway and raising the dam's wave wall, it now meets the revised standards of the NSW Dam Safety Committee and provides greater control of extreme flood levels in the dam.
A number of innovations during design and construction resulted in the project being delivered on schedule and $300,000 under budget.
During the ceremony, Local, State and Federal Government representatives praised the innovation of the project management team, which included construction contractors, Entracon Civil, Tweed Shire Council, NSW Office of Water and NSW Public Works.
Innovations during design and construction helped to overcome a number of challenges, including the terrain and extreme weather and flood risk, but also resulted in the project being delivered on schedule and $300,000 under budget. Innovations included:
- The design and construction of an angled spillway crest to increase the length of the spillway and enable more water to pass over it at any one time, while also avoiding costly excavation into the adjoining extremely hard rock face.
- Pouring more than 200 concrete blocks onsite to reduce transportation time and cost. These blocks could also be reused if the storage capacity of the dam is ever increased as part of future supply augmentations."
- To overcome the issue of limited access at the site, an 85-tonne crane was perched on top of the existing dam wall, a feat within itself. The crane was used to move building material and machinery into and around the construction site.
The event was also attended by members of Council's Aboriginal Advisory Committee, descendants of former Tweed Mayor, Clarrie Hall and other guests.
New signs at the site further recognise the cultural significance of the local area for Indigenous culture.
The State Government contributed $1.2 million to the project.
Clarrie Hall Dam Reopening Photos (2.84mB PDF).
About the Upgrade
The upgrade provides greater control of flood levels in the dam. The $7.3 million project increased the spillway capacity to ensure the dam can safely pass extreme flood events in accordance with new standards established by the NSW Dam Safety Committee.
When Clarrie Hall Dam was commissioned in the early 1980s it complied with the engineering standards of the day. Since then however, the NSW Dams Safety Committee have revised these standards as access to rainfall and extreme weather predictions and data has improved.
Clarrie Hall Dam can pass floods many times greater than the largest flood on record. However, Tweed Shire Council has now upgraded the dam’s spillway capacity to ensure the dam continues to meet safety requirements and more importantly protects the safety of public and property downstream of the dam in the unlikely event of extreme flood.
Construction is complete
Construction involved widening and extending the existing spillway.
The upgrade raised the spillway crest and there was no change to the storage’s full supply level or the storage inundation area. However, an existing parapet wave wall across the dam crest was raised to avoid overtopping of flood waters and create a larger margin between the top water level and the top of the dam structure.


The water level in the Narayani River has crossed the warning level due to continuous rains. According to the Department of Water and Meteorology, the water level in the Narayani River has risen above 7.3 and reached 7.8 meters.
It is considered to have reached the danger level after reaching above 8 meters.
It has been raining continuously in Chitwan since last night. The District Administration Office, Chitwan, has urged to remain vigilant as the water level in Narayani may rise further due to continuous rains in the hilly areas. As the water level in Narayani rises, it increases the risk of erosion and inundation in the western Chitwan region.
The Narayani River has been causing more damage in wards 26, 27 and 28 of Bharatpur Metropolitan City. The District Administration Office, Chitwan, has already issued a notice urging people to be vigilant to avoid possible risks as the flow of water in the river is increasing.

Abstract Numerical simulations were conducted in a helical axial-flow multiphase pump under water single-phase and air-water two-phase flow conditions to quantitatively analyze energy transfer characteristics of the fluids in the impeller, respectively. By demonstrating the energy transfer characteristics in the impeller, the relationships of flow rate and inlet air volume fraction with the work done in diffe-rent regions of the impeller were revealed. The results show that the impeller mechanical energy is mainly transferred to the fluids in the middle region of the impeller, and the most energy transferred is in static pressure. Further, the impeller capacity of doing work firstly increases and then decreases from the impeller inlet to the outlet. Under water single-phase flow conditions, with increasing flow rate the impeller capacity of doing work is gradually enhanced in forepart of the impeller but weakened in rear part. Under air-water two-phase flow conditions, with increasing inlet air volume fraction, the impeller capacity of doing work is degraded gradually, especially for forepart of the impeller, and the capacity in rear part is less affected. These results can provide a reference for the optimal design of flow components of the helical axial-flow multiphase pump.

Brockton Drive Dam
- Lake & Dam Preservation
- Approximately $4.5 million
- Stormwater Management (Lead)
- CDM Smith, Inc.
- Carolina Civil Works, Inc.
- Public Utilities Department
Posted Tuesday, May 15
Construction for the first phase of this project is nearly complete. The project includes draining the lake, replacing stormwater drainage and sanitary sewers, and transforming the upper lake to a stream channel. The new stream channel flows through the newly constructed stormwater infrastructure into the lower lake. Final work, including additional grading/leveling and planting in the project area, will be complete over the next few weeks.
Since the dam structure at the lower lake is not functioning properly, the lake will be drained through the start of the second phase of this project. This will limit the amount of water in the lake, which will reduce impacts from heavy rain storms and ensure the ongoing safety of residents living near the lake.
For your safety, residents are not permitted to enter the construction site. Work hours will be Monday through Friday from 7:30 a.m. to 5:30 p.m. with no work scheduled on the weekend or City holidays except in an emergency or with prior approval from the City.
If you have any questions about upcoming construction, contact Todd Rall, at 919-996-4006 or Todd.Rall@raleighnc.gov.
This project will provide dam and storm drainage improvements at the Brockton Drive dam by addressing dam safety concerns, reducing the frequency and severity of flooding in adjacent structures, and improving water quality, while remaining consistent with the City of Raleigh's Lake Preservation policy.
The Brockton Drive Lake and Dam Rehabilitation will be completed in two phases:
Phase I - Upper Dam: This phase includes removing the upper lake to restore the channel at Brockton Drive and increasing the size of the existing drainage pipe with a box culvert. Stream restriction at the downstream corner of Walden Woods Club House pool will be removed. The stream also will be stabilized and reshaped with plants/vegetation at the upper stream channel.
Phase II - Lower Dam: The spillway structure on the lower dam will be replaced and then the lower dam will be replaced with a roller-compacted concrete structure.
