A commercial CFD code is used to compute the 3-D viscous flow field within the impeller o( a centrifugal pump. Several preliminary numerical calculations are carried out to determine the influence of the parameters such as the grid systems, the numerical schemes, the turbulence models and the shape of the vaneless diffusers at the design flow rate. The results of the preliminary study are used for the calculation of the off-design flow conditions. The circumferentially averaged results such as the radial and tangential velocities, the exit flow angle, the slip factor, the static pressure and the total pressure are compared with the experimental data at the impeller exit to discuss the influence of the prescribed parameters.

After years of work, the Brandon eastern access route is complete, allowing smoother and more efficient access to Brandon, Manitoba for commercial and personal vehicles. Included in the $44-million project, which has been under construction since the mid-1990s, is a flood protection system.
The system, which was built in the project’s final phase, includes a pumping station and drainage network which were installed to lessen the chances of the roadway underpass being closed during flooding.
Also included in the project were the construction of two major bridge structures and three sections of highway. The project is part of $600-million provincial plan to upgrade highways, bridges, and roads across Manitoba.


The Dasu hydropower project (HPP) is a 4.32GW run-of-the-river hydroelectric power facility planned to be developed in two stages on the Indus River, approximately 7km upstream of the Dasu town, Kohistan, Khyber Pakhtunkhwa, Pakistan.
Pakistan’s Water and Power Development Authority (WAPDA) is the implementing authority of the project.
Early construction works on the Dasu hydropower project stage one were started in June 2017. Estimated to cost $4.2bn, the stage one will comprise six generating units with a combined installed capacity of 2.16GW.
Scheduled for commissioning in 2023, the Dasu stage one is expected to generate approximately 12,222GWh of clean electricity a year. It is estimated to generate more than 8,000 jobs for the local residents.
WAPDA plans to initiate the Dasu hydropower plant stage two with a similar installed capacity after the completion of the Diamer Basha project, which is currently under construction on the River Indus in Gilgit-Baltistan.
Upon completion of both the stages, Dasu will be one of the biggest hydroelectric facilities in South Asia.
Dasu hydropower project background
WAPDA initiated studies on the hydropower development potential of the Upper Indus Basin area in Pakistan in the 1980s. The Dasu HPP proposal was approved under the Government of Pakistan’s Vision 2025 program in 2001.
Feasibility study on the project was completed in 2009, while contracts for preparatory works of the project were awarded in the first half of 2015.
Dasu hydropower project location and site details
The Dasu hydropower project site is situated in a deep and narrow valley of the lower Himalayas at an altitude of 800m above sea level (MASL).
Located in the remote mountainous terrain in the Upper Indus valley, the site will be accessed through the realignment of a 65km stretch of the Karakoram Highway (N-35).
Dasu hydropower facility make-up
The Dasu hydropower facility will comprise a 242m-tall roller compacted concrete (RCC) with 570m crest length, eight spillway gates, two flushing tunnels, four circular headrace tunnels, an underground power house on the left bank of the river, four 2.2km-long tailrace tunnels, and a switchyard.
The RCC dam will create a 73km-long and 733m-wide reservoir with a gross storage capacity of 1.4 billion cubic metres (bcm). The maximum gross head for the hydroelectric facility will be 184m.
The underground power house will be equipped with six 360MW vertical shaft Francis turbine generator units in each stage of the project development.
The electricity generated by the Dasu hydropower station will be fed into the national grid through two parallel 250km-long, 500kV transmission lines connecting the Pathar Garh grid station near Hassanabad.
Pakistan’s state-owned National Transmission and Dispatch Company (NTDC) will be responsible for the development and operation of the transmission infrastructure for the project.
The World Bank approved an International Development Association (IDA) credit of $588.4m and an IDA Partial Credit Guarantee (PCG) of $460m for the Dasu hydropower project stage one in June 2014.
WAPDA secured PKR144bn ($1.36bn) financing for the project from a consortium of seven local commercial banks led by Habib Bank (HBL) in March 2017.
Further, Credit Suisse Bank agreed to provide a $350m debt facility for the project in June 2017. The remaining funds will be provided by WAPDA and the Government of Pakistan.
China Civil Engineering Construction Corporation (CCECC) was awarded contracts worth $170m for the preparatory works of the project in March 2015.
Power China was awarded a $17m contract for a 45km-long, 132kV transmission line from the Dubair HPP to the Dasu project site in April 2015.
The main civil works contracts worth PKR180bn ($1.7bn) were awarded to China Gezhouba Group Company (CGGC) in March 2017. The scope of the contracts includes construction of the dam, the underground power complex, and associated structures.
CGGC subcontracted Beifang Investigation, Design & Research for providing design and technical services in May 2017.
Zhongmei Engineering Group received two contracts worth $22m for resettlement works related to the Dasu hydropower project in April 2017.
China Gansu International Corporation for Economic and Technical Cooperation (CGICOP) was awarded a $46m contract for the construction of accommodation and support infrastructure facilities for the project in October 2018.
Tractebel was awarded the project monitoring consultancy services contract for the Dasu hydropower project in May 2019.


Indiana Michigan Power will start raising the level of the St. Joseph River upstream of the dam at Johnson Street in Elkhart on Monday, March 17.
The level upstream of the dam, formally known as the Elkhart Hydroelectric Generating Station, was lowered two feet last December to prevent ice buildup at Six Span Bridge, the C.R. 17 crossing over the river. The level is to be raised back up over three or four days, Indiana Michigan Power said in a statement Wednesday, March 12.
Those living up to eight miles upstream of the dam "may wish to make note of this in case there is any work they would like to finish along the river bank before the level rises two feet," said the statement.
The Elkhart dam generates 3.44 megawatts of power and is one of six hydroelectric plants I&M owns along the river.

Mine submersible pump operation current assembly caused by the protection switch trip, the main reasons for the current major following:
1. The pump to the wrong:
Reverse rotation, compared with normal steering, reverse rotation when the pump water significantly reduced. Correction method: the power line of three cores in any two exchange.
2. Mining submersible pump flow is greater than the normal range :
Flow is too large, shaft power is large, motor overload. Countermeasures, adjust the valve, reduce flow, so that pump flow in the normal range of application.
3. Mining submersible pump supporting motor guide bearings, thrust bearings, impeller, pump rubber bearings, sealing rings of varying degrees of wear :
These wear will make the pump working state is poor, than this serious consequence is that the pump is damaged, the stator winding burn. Countermeasures: find out the cause of wear after repair or replacement of damaged parts, remember to check the mechanical seal is intact, if the mechanical seal damage, should be replaced by a new.
4. Mining submersible pump shaft bending, bearing not concentric :
Found immediately after the overhaul, straightening shaft straightening, bending degree should be less than or equal to 0.05mm/m, and replace the bearing failure, re assembling mine submersible pump.

DYNASET HPW Hydraulic High Pressure Water Pump lineup gets a new pump model called HPW 160. This new pump model is specially designed to power up HPW Dust applications. Like you probably know, HPW Dust is a DYNASET product family for dust control in the industries of demolition and mining, for example. The new pump can be also used for power washing applications.
How Does It Differ from The Other Models?
The most obvious thing that differs from other HPW pump models is the power output. This pump produces 160 bar pressure and a flow of 18 l/min. One of the major differences to other pumps is a brand-new piston model. The new piston model of these pumps has made them extremely compact because the structure has been simplified.
This pump is the smallest of the HPW line up in dimensions. The height of the pump is only 110 millimeters, width is 210 mm and length is 100 mm. Even though the dimensions of it are so compact, the output power it, 4,8 kW, still beats most of the electric power washers.
And Where to Use It?
This new HPW pump model, HPW 160 is especially meant for dust control applications. It can be used for example for street sweeper dust control and for dust suppression of small pulverizers and drilling rigs.
The new model is available by default in three different versions like the other pump models. The first one is a basic model without any additional valves. The second model has a water unloader valve which makes power washing application possible with the pump. The third model is the VR-PA-model. This model has a special valve, that makes sure that the hydraulic oil flow won’t exceed the set value.

The project is located in northeast Chanhassen, off of Pleasant View Road in Pleasant View Preserve. The project involves ravine stabilization and improvements, including check dams leading into Silver Lake. The check dams will be reinforced with iron enhanced sand filters. As the water filtrates in the check dam, the iron in the sand allows for additional phosphorus removal from the stormwater. A cross section of one of the check dams can be found below.
Additionally, the project would include minor street and stormwater improvements to Pleasant View Road adjacent to the ravine. The overall goal of the project is to stabilize the eroded ravine, reduce phosphorus loading and thus improve the water quality in Silver Lake.


(Business in Cameroon) - Chinese construction and engineering company China Gezhouba Group has been commissioned to carry out the studies, construction of the 600MW Chollet hydroelectric dam, and operate it under a BOD (Build Operate and Transfer) contract.

SMEC South Africa is a member of the Metsi a Senqu-Khubelu Consultants Joint Venture, appointed to design the tunnels for Phase II and lead construction supervision. Phase II will increase the current water transfer rate of 780 million cubic metres per annum incrementally to more than 1,270 million cubic metres per annum. At the same time, the quantity of electricity generated at the Muela hydropower station will exceed 500GWh per year and is a further step in the process of securing an independent electricity source to meet Lesotho’s domestic requirements.
In August 2021, Lesotho Highlands Development Authority (LHDA) celebrated a significant milestone in the construction of Phase II of LHWP with the double breakthrough of the projects two diversion tunnels. The breakthrough marked the completion of 1,870m of tunnel excavation. The 7m and 9m diameter tunnels were excavated by both drill and blast method and achieved the breakthrough on the same day.
The diversion tunnels will enable dry zones for the construction of the Polihali Dam, to ensure the site is uninterrupted by the river flow. The construction methodology incorporated concrete intake structures and a range of concrete lining methods. The team used shotcrete, in-situ reinforced concrete and invert concrete lining to optimise the process. The delivery team overcame challenges such as the COVID-19 pandemic, harsh weather conditions and flooding of the Senqu River which affected the construction site in January 2021.
SMEC is also working on the Polihali Transfer Tunnel contract, which involves the design and construction supervision of the 38km long water transfer tunnel from the planned Polihali Dam to the existing Katse Dam. The tunnel is to be largely excavated by tunnel boring machine but also includes significant lengths of drill and blast tunnelling. The scope incorporates two gate shafts which will be used to manage future operations. Each gate shaft will include stoplogs, gates, dewatering pumps and filling valves. A notable technical feature of the project is the Katse lake tap, where the tunnel is designed to be excavated into a dam basin below water level. Construction of the 38km section of tunnel is expected to commence mid-2022.

North East Water has appointed Mott MacDonald to investigate the performance of sewerage systems in Yarrawonga, Wodonga and Wangaratta in north east Victoria, Australia.
Mott MacDonald said that the project aims to understand the current and anticipated future performance of the sewerage systems under the influences of urban growth and wet weather.
The global consultant said that it will install 46 flow monitors and 12 rain gauges to monitor flows within the system over a 12 week period. It said the results of this would then be used to model growth related to dry weather flows and wet weather flows across a range of average recurrence intervals.
Using MikeUrban software and the H2Kn0w-how specialist hydraulic assessment tool developed by its in house team, it will analyse flow data to identify any likely issues with inflow, infiltration or other hydraulic issues. This will work towards building, calibrating, and master planning the entire flow modelling stage.
Mott MacDonald project director Peter Stephens said: “The models will be used to develop options that will accommodate future growth and reasonable wet weather flows in the sewerage systems. The projects identified will be put forward for design and construction, mainly over the next five year planning period from 2017-22.”
The project is expected to be completed in the middle of 2016.

The overhaul of the 208 km-long left canal of the Jayakwadi dam in Maharashtra's Chhatrapati Sambhajinagar will cost Rs 3,300 crore and will increase the carrying capacity by 1100 cusecs, an official said on Monday.
The irrigation department has prepared a detailed project report (DPR) to undertake an overhaul of the left canal of the dam that goes from Paithan to Parbhani district, the official said.
"The DPR is almost ready, and the project will cost Rs 3,300 crore. The canal cannot handle the pressure of water released over 2100 cusecs. As a result, the water reaches late to the tail end of the canal," Samadhan Sabbinwar, chief engineer of the irrigation department, told PTI.
While the designed capacity of the left canal is 3600 cusecs, water was never released above 2800 cusecs, he said.
With the overhaul, the canal will be able to carry 3200 cusecs water, increasing the carrying capacity by 1100 cusecs, he said, adding that the DPR will be submitted to the state government for further sanctions.

The Goldendale energy storage project is a 1.2GW closed-loop pumped storage hydropower station planned to be developed in Washington, US.
Estimated to cost £1.5bn ($2.1bn), the project was previously owned by a joint venture of Rye Development and National Grid.
The fund management company Copenhagen Infrastructure Partners (CIP) acquired the ownership of the project in November 2020, while Rye will continue to lead the project until the start of construction activities.
The project was issued a preliminary permit by the US Federal Energy Regulatory Commission (FERC) in March 2018, while the final license application was filed in June 2020.
Scheduled to come online by 2028, the Goldendale energy storage project is estimated to have an operational life of more than 80 years. The facility is intended to supply renewable energy to the utilities in the Pacific Northwest and California.
Location and site details
The Goldendale pumped storage hydropower station will be built on a 681.6acre-site comprising private lands northeast of Portland and southwest of Kennewick, on the Columbia River, next to John Day Dam.
The pumped-storage facility will be primarily located in Klickitat County, Washington with transmission line extending into Sherman County, Oregon.
Goldendale energy storage project components
The Goldendale pumped storage project will have an underground powerhouse equipped with three Francis-type, reversible, variable-speed closed-loop pumped-storage power generating units of 400MW capacity each.
The units will be operating at a rated gross head of 2,360ft, while the maximum water discharge capacity is estimated to be 8,280 cubic feet per second.
The project will also comprise an upper and lower reservoir with a usable storage volume of 7,100 acre-feet, and an underground water conveyance tunnel.
The upper reservoir will have an ungated vertical intake structure covered with a hood to prevent vortex formation. The lower reservoir will be constructed as a horizontal intake concrete structure with steel slide glass gates that will allow isolation of tailrace tunnel from the lower reservoir.
The water conveyance system of the project will include a 29ft-diameter, concrete-lined vertical shaft, one 29ft-diameter, concrete-lined headrace tunnel, three 15ft-diameter steel-lined penstock tunnels, one 30ft-diameter concrete lined-tailrace tunnel, and three 20ft-diameter steel-lined draft tube tunnels, along with a slide gate which will be used to isolate pump-turbines from the lower reservoir.
The electricity generated power at the power station will be routed via 18/155kV intermediate step-up transformers housed in the transformer gallery located adjacent to the powerhouse to an outdoor 115/500kV substation and switchyard located near the lower reservoir.
The project will also connect with the John Day substation which is identified as the preferred connection point for interconnection by Bonneville Power Administration (BPA).
Initial fill water and periodic make-up water required for the Goldendale energy storage project will be purchased from Public Utility District No. 1 of Klickitat County (KPUD) using a KPUD-owned conveyance system located adjacent to the project.
The potential commercial off-takers for the project include Puget Sound Energy (PSE), PacifiCorp, Los Angles Department Water & Power, and Tacoma Power.

The multi-purpose Hirakud Dam across the river Mahanadi was constructed for flood control, irrigation and power generation. Hirakud Dam is a composite structure of earth, concrete and masonary. The Main dam having an overall length of 4.8 km spans between hills Laxmidungri on left and Chandli-dungri on the right. The dam is flanged by 21 km long earthen dykes, both on left and right sides to close the low saddles beyond the abutment hills. It has the distinction of being at one time the longest earth dam in the world, being 25.8 km long with dams and dykes taken together. It also has the rare distinction of forming the biggest artificial lake in Asia with reservoir spread of 743 sq. km at full reservoir level. Hirakud dam intercepts 83400 sq. km of Mahanadi catchment. The reservoir has live storage of 4-36 million Acer feet with gross storage of 5-83 million Acre feet.
Water from dam enters the turbine through trash rack, intake structure and penstock and gets discharged to the tailrace through draft tube. To control the flow, hydraulic intake gates are provided for each machine. The power component of HPS consists of Power House | at Burla and Power House and Power House - II at Chiplima
The main features of Stage I are dam and appurtenant works, canal system and power generation & transmission. Initially Four generating units with installed capacity 123 MW (2x37.5 + 2x24) were completed in PH-I at Burla.

VIJAYAWADA: Water level in all the reservoirs in Andhra Pradesh on May 31, the last day of the Water Year, is nearly double than the level of last year. The total water level has stood at 478.22 TMC as against 244.13 TMC last year. The quantum is 48.62 per cent of the total gross capacity of 983.48 TMC of reservoirs.
According to the data available with the Water Resources Department, the gross capacity of major reservoirs in the State is 865.64 TMC and on the last day of the Water Year 2021-22, the water level was 423.4 TMC, while it was 208.78 TMC last year on the same day.
Similarly, water available in the medium reservoirs in the State on May 31, is 53.69 TMC, which is 46.65 per cent of the gross capacity of 115.09 TMC of medium reservoirs. Last year, it stood at 35.27 TMC. Gross capacity of other reservoirs (minor) is 1.62 TMC. A total of 1.12 TMC is available now, which is 69.04 per cent of the gross capacity. The water level in the projects stood at 0.07 TMC last year.
Officials attributed the more water level to heavy rains received during monsoon last year, besides copious inflows from upstream projects. Srisailam reservoir, which got 33.64 TMC water last year, has 38.57 TMC now, while its gross storage capacity is 215.81 TMC. Nagarjuna Sagar has 180,09 TMC water this year.

Fixed-Cone Valves, New Melones Dam, California. Hydraulic Model Investigation.
Final rept. Feb 68-Jul 78,
ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MS HYDRAULICS LAB
Pagination or Media Count:
This model study was conducted with the major emphasis on determining the differential pressures acting on the vanes of the valves. Pressures were measured along the vane, and the differential acting across the vane was used in a structural analysis. Flow entering the 66-in.-diam valves in the low-level outlet works was highly distorted by the combined bends located just upstream of the valves. The upstream bifurcations in the flood control and irrigation outlet system caused substantial fluctuation of flow entering the 78-in.-diam valves. Discharge characteristics of the valves showed that the eight-vaned valves without the center connecting hub design used in the New Melones Dam outlet works have discharge coefficients slightly higher than conventional four- and six-vaned valves with center connecting hub. Approach conduit pressures were measured at all potential low pressure zones and no low pressures were measured. The original hood design was modified to reduce backsplash on the valves. In the low-level outlet works, the backsplash plate was moved downstream 4 ft from the original location and backsplash was substantially reduced. In the flood control and irrigation outlet system a divergent cone was used in lieu of the plate to reduce backsplash. Results of the study are considered valid for use in designing against fatigue failure of the vanes. Although frequency spectra determined that predominant frequencies were low, the possibility of a resonant failure cannot be ruled out.

The Signature® Flowmeter is designed for open channel flow monitoring applications using any combination of flow and parameter measurement technologies and sampling, depending on what is required at the measurement site. The bubbler level sensor can be used in almost any open channel flow application and performance is unaffected by steam or foam on the surface of the water. The bubble line is anchored in the flow stream at the appropriate measuring point in the weir, flume, or other open channel flow situation. The pressure in the bubble line is proportional to the liquid level in the flow stream sensing the liquid level.
Teledyne Isco’s TIENet™ 330 Bubbler Module technology is ideal in flow streams affected by harsh weather, debris, or corrosive chemicals. Since the depth of flow is determined by measuring the pressure needed to force bubbles out of the line, you are able to calculate flow rate using one of the meter’s built-in flow conversions, or a user-defined level-to-flow relationship.Signature Flow Meter
The new Isco Signature flow meter is designed for open channel flow monitoring applications. It supports flow measurement technologies including ultrasonic and bubbler. Flow can be calculated using standard open channel level-to-flow conversions, level to flow data points as well as user-defined equations, depending on the needs of the application. Unique features provided by the Signature flow meter help to verify data integrity. It logs key events such as power outages and changes in calibration to validate data accuracy. Stored data can be easily reviewed to detect any type of data alteration.

River engineers commonly need to predict sediment transport rates in the absence of adequate field data, and so make frequent use of numerical sediment transport models. This paper compares the performance of two such computer models for the prediction of graded sediment transport. The intention is to inform model users of the level of accuracy that can be expected for typical applications. One model uses the Parker bedload transport equation and the other uses the Meyer-Peter and Müller sediment transport formula modified for use with graded sediments. The computer model predictions are compared with detailed experimental data collected for the purpose of computer model validation. The Meyer-Peter and Müller-based model produces better predictions of sediment transport rates, whereas the Parker-based model performs better in terms of the grain sizes of both the bedload and the bed material. These results illustrate the limitations of present models and indicate areas requiring further investigation.

River Valley Projects of River Ganga
Multipurpose river valley projects in India were started with the basic aim of meeting the critical requirements of irrigation for agriculture, electricity for industries and flood control. The importance of the dams at that time can be inferred from the fact that dams were regarded as “the temples of modern India” by J.L Nehru. Accordingly, dam construction was given such a high priority in India’s economic plans. Tehri Project, Ramganga Project, Tanakpur Project, Gandak Project, Kosi Project, Rihand Project, Bansagar, Matatila Project, Chambal Project, Damodar Valley and Mayurakshi Project are the important river valley project link with Ganga River Basin.
• Tehri Project: It has been constructed at Tehri at the confluence of the rivers Bhilangana and Bhagirathi.
• Ramganga Project: It is constructed on the river Ramganga, tributary of Ganga.
• Tanakpur Project: It has been executed at Tanakpur (Uttarakhand) on the river Kali that flows on the Indo-Nepal border.
• Gandak Project: It is joint project of Bihar, Uttar Pradesh and Nepal. Hydro-electricity is produced at Suratpura (Nepal) on the river Gandak. The dam has been built at Bhaisalotan (Valmikinagar) in Bihar.
• Kosi Project: It is a joint project of Bihar and Nepal. The main objectives of this project are flood control, hydro-electricity production and irrigation. Kataiya in Nepal produced Hydro-electricity. The main canal in Bihar has been drawn out from the Hanuman Nagar Barrage.
• Rihand Project: It has been executed at Pipri (Sonebhadra district, Uttar Pradesh) on the river Rihand, a tributary of the son.
• Bansagar Project: It is joint project of Madhya Pradesh, Uttar Pradesh and Bihar on the son. It has been built on the son in the district of Shahdol in Madhya Pradesh.
• Matatila Project: It is joint project of Madhya Pradesh and Uttar Pradesh on the river Betwa. The dam has been built in Uttar Pradesh.

Ethiopia: home to Africa’s tallest dam
Africa’s tallest dam and biggest capacity are the words that describe Ethiopia’s dams currently under construction. The country will be a land of many distinctions when the current crop of hydropower stations is completed.
Ethiopia’s mountains and being the source of over 90% of the Nile’s water offer the potential of over 40,000MW of hydropower. The recently completed Tekeze Dam holds the distinction of being the tallest Dam in Africa overtaking, by 3 m, the Katse Dam in Lesotho which previously carried that title.
The dam was built by the Chinese National Water Resources and Hydropower Engineering Corp and consists of the arch dam, two river diversion tunnels, power waterways, an underground powerhouse containing four 75-MW Francis turbines, a 230-kV substation, and a 105-km transmission line to connect the project to the national grid at Mekele.
The country’s hydropower development plans also include the Gibe III dam and the Grand Renaissance Dam. The Gibe III will be the highest roller-compacted concrete dam and will inject 1,870 MW of power into the national grid while the Grand Renaissance will add 6,000 MW making it the largest hydroelectric power plant in Africa.
When all these dams are completed the country will have excess power capacity and be able to export this to other East African countries


WASHINGTON, D.C. – Secretary of the Interior Dirk Kempthorne today announced that the Bureau of Reclamation has awarded a $48,745,838 contract for Phase II of the Joint Federal Project at Folsom Dam and Reservoir. The award, which is the second in a series of construction contracts for a new auxiliary spillway at Folsom, went to Oregon Mt. Construction of Redding, California.
“This project significantly enhances flood control and dam safety for downstream communities, including Sacramento,” Kempthorne said. “Because we are doing this work as a joint federal-state effort, the project creates cost efficacies that save American taxpayers a significant amount of money.”
The auxiliary spillway, or Joint Federal Project, represents an unprecedented partnership among Reclamation, the U.S. Army Corps of Engineers, the Central Valley Flood Protection Board, and the Sacramento Area Flood Control Agency. When completed, the project will address the hydrologic risk to Folsom Dam identified through Reclamation’s Safety of Dams evaluation program. Hydrologic risk refers to possible overtopping of the dams and dikes during an extreme storm event. The project also achieves the Corps’ objective of increasing flood control at Folsom.
The initiative consists of a water-side approach channel, a control structure with six submerged gates, a concrete-lined spillway chute about 3,000-feet long, and a stilling basin which acts as an energy dissipation structure prior to discharges converging with the American River below the main concrete dam. The project will be constructed in three successive phases by Reclamation and the Corps.
