Discharge Equation of Ice Harbor Type Fishway

Spawning a Hydroelectric Plant
A hydroelectric facility which utilizes fishway attraction water on the Columbia River between Washington and Oregon will tap a neglected source of power and save many endangered fish...

Surface Oriented Fishway and Fish Guidance Curtain
We, the the U.S. Army Corps of Engineers, Walla Walla District, are developing a juvenile salmonid surface bypass and collection prototype for Lower Granite Dam. One of the more promising...

McNary Dam Fishway Hydroelectric Project

An Improved Design of Fishways Under High Variation of Headwater
For the purpose of mitigating environmental impact, it is necessary to build fish passing facilities for fish migration when a dam is constructed on a river. But when the headwater variation...

Cost-Effective Solutions to Fishway Design

Evaluation of an Eicher Fish Diversion Screen at Elwha Dam
In the spring of 1990, the Electric Power Research Institute (EPRI) initiated testing of an inclined fish screen installed in a 9-foot diameter penstock at the Elwha Hydroelectric Project...

Harvest Facility Protects and Improves Fishery
By constructing a trap and transfer/harvest facility to control anadromous fish migration, the trout fishery on the Boardman River was protected and the salmon fishery was improved. The...

Relative Survival of Juvenile Chinook Salmon Through Bonneville Dam on the Columbia River
Preliminary results of a multiple year study indicate that juvenile chinook salmon passing through the juvenile bypass system at Bonneville Dam second powerhouse during the summer have...

Atlantic Salmon Smolt Movement and Behavior at Vernon Hydroelectric Station
Behavior of emigrating Atlantic salmon smolts (Salmo salar) was studied at New England Power Company's (NEP) Vernon Hydroelectric Station located on the Connecticut River,...

Gropps Lake Dam
Gropps Lake Dam has a concrete ogee spillway with earthen abutments at either end of the spillway. The dam features an internal drainage system, outlet works, an energy dissipator, a steel...

Fishery Issues Slow Boardman River Redevelopment
At issue was the requirement of the Michigan Department of Natural Resources (MDNR) and the U. S. Fish and Wildlife Service to require the establishment of fish ladders at the hydro sites....

Fishways--Historical Assessment of Design Practice
Fishway design has evolved over the years in a conservative fashion. Research has led to the development of some innovative structures, but costs and water usage have been high. Conservative...

Connecticut River Fishways: Model Studies
The fishways at the Vernon and Turners Falls Dams were optimized by use of hydraulic model studies. In both cases, slotted weirs were modified so that a better head loss distribution was...

Cowlitz Salmon Hatchery
The Cowlitz Hydroelectric Project, located on the Cowlitz River and owned by the City of Tacoma, consists of two developments: Mayfield and Mossyrock Dams. Many studies were made to design...

Wells Hydroelectric Project Fish Facilities
The development of the fish passage and fish spawning facilities for the Wells Hydroelectric Project is described. Because the spillway and powerhouse are combined into a single structure...

Hydraulic Design of Dworshak Dam Diversion Facilities
The facilities used for river diversion, log passage, and migratory fish passage are described with respect to hydraulic problems and design criteria. Diversion was accomplished by use...

Model and Prototype Research on Fish Ladders
Description of 3 major fishway installations operated by Corps of Engineers, 2 more under construction, and several in planning stage; results of studies to determine most efficient solutions;...
