A Demonstration of Strobe Lights to Repel Fish
An EPRI review (EPRI, 1986) of fish protection systems for hydroelectric facilities identified strobe lights as a potential behavioral system to minimize fish entrainment. In 1988, EPRI...

Techniques for Balancing Instream Flow Needs with Project Operation
Balancing power and non-power benefits of hydroelectric developments has become a controversial issue in the relicensing of projects. Multiple project and multiple objective flow management...

The Use of IFIM for Evaluating Effects of a Flow Alternative on Fish Habitat in a River System with Competing Water Demands
The Instream Flow Incremental Methodology (IFIM) was used to evaluate instream fish habitat in the Platte River in central Nebraska. The IFIM analysis presented herein incorporates 1)...

Altering Federal CVP Power Operations to Accommodate Fisheries' Survival on the Sacramento River
Balancing the needs of the river users, water and power users, and the fishery needs is a formidable task requiring sacrifices by all the users particularly during this time of drought...

Evaluation of Alternatives for Providing Minimum Flows Below TVA's South Holston Dam
TVA is in the initial phases of a project to provide minimum flows in the South Fork Holston River below South Holston Dam. The purposes of the minimum flows at South Holston are to enhance...

Twin Falls Mitigation Plan: Long Term Monitoring of Fish Populations
A fishery monitoring and enhancement plan has been worked out for the Twin Falls Hydroelectric Project which diverts water from a one mile reach of the South Fork Snoqualmie River in Washington...

A Water Budget Approach to Instream Flow Maintenance
Storage reallocation is a current issue at many Federal water storage facilities that have hydroelectric generation. Allocation of storage to support instream flows is one of the changes...

Instream Flow Needs Below Peaking Hydroelectric Projects
A method has been developed to assist in the determination of instream flow needs below hydroelectric projects operated in a peaking mode. Peaking hydroelectric projects significantly...

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...

Case Study: Central Oregon Siphon Power Project Mitigating Local Concerns
In the early 1980's, 18 hydroelectric projects were proposed for development on the Deschutes River system in Central Oregon. Strong local opposition was a major factor in...

North Fork Feather River Erosion Control Program
PG&E, an investor owned gas and electric utility serving northern and central California, has been engaged since 1984 in the development and implementation of a regional erosion...

Glen Canyon Hydropower vs. The Grand Canyon (The Conflict of Basic Values)
Competing for the scarce resources of our future is the byword of the 1990's. For the last century and more, the United States has been in the position of always having more...

Cooperation and the Endangered Species Act
Passage of the Endangered Species Act (ESA) in 1973 set the stage for some of the nations most polemic environmental battles. One of these is in the Colorado River Basin which is home...

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...

Design of Extended Length Submerged Traveling Screen and Submerged Bar Screen Fish Guidance Equipment
The hydropower projects on the Snake and lower Columbia Rivers in the Pacific Northwest are unique because these rivers are also the spawning grounds for migratory salmon. The salmon swim...

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,...

Harrisburg Hydroelectric Project?Water Quality Issues
The Harrisburg Hydroelectric Project is a proposed 34.4 MW hydroelectric facility on the Susquehanna River near Harrisburg, Pennsylvania. The project will consist of a 16.5 ft high gated...

Feasibility of Adding Small Hydro to Federal Hydraulic Structures in the Upper Ohio River Basin
A national hydropower program exists in which non-Federal interests may develop power at Federal hydraulic structures which have that potential. This paper discusses associated considerations...

Yough Hydro Case History?Development 12 MW Facility
The Youghiogheny Hydroelectric Project (Yough Hydro Project) is licensed with the Federal Energy Regulatory Commission (FERC) as Project No. 3623. The project is a run-of-the-river facility...

Overcoming the Obstacles?Hydroelectric Development on the Kankakee River
A number of difficulties were encountered and resolved during development of a 1,200 kW hydroelectric project in northeastern Illinois. Located at the site of an abandoned hydroelectric...
