Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...
Status of the Spiny Lobster (Crustacea: Palinuridae) Stocks Off Northeast Brazil in Relation to Fishing Effort and Environmental Conditions
Conditions for the development of relatively abundant populations of spiny lobsters of genus Panulirus, mainly P. argus and P. laevicauda, off Northeast Brazil are consistent with hydrologically...
Management of Fisheries in the State of Rio De Janeiro, Brazil
To improve the interdisciplinary knowledge and to subdivide the problem in bio-ecological sectors, international committees recommend the development of integrated evaluation groups. On...
Aquatic Weed Control by Grass Carp in Cool Water
Diploid grass carp have significantly controlled problem aquatic vegetation during a 3-year study in a northern Colorado irrigation canal where water temperatures ranged from 0 to 25?C....
Dam Rehabilitation and Fish Lift Design at the Pejepscot Hydroelectric Project
The rehabilitation work on the existing rockfilled timber crib dam comprised an assessment of the existing dam stability; analysis of the existing hydraulic conditions to establish the...
Negotiating with State and Federal Fish and Wildlife Agencies
The Federal Power Act of 1920 (Act), as amended by the Electric Consumers Protection Act of 1986, requires that the Federal Energy Regulatory Commission, in order to adequately and equitably...
Overview of EPRI's Hydro Program
The near term objective of the Electric Power Research Institutes (EPRI) Hydro Program is to provide practical and easily used research results and industry guides in the areas of dam...
Fishery Assessments at Hydroelectric Projects Using Electrofishing, Nets, and Hydroacoustics
Assessments of fish population and entrainment were made at a hydroelectric generating station and spill dam on the Ohio River. By combining complementary sampling techniques, full assessments...
Managing the Columbia River to Meet Anadromous Fish Requirements
According to northwest fishery agencies and Indian tribes the protection for juvenile salmon and steelhead is not adequate. The Northwest Power Planning Council, formed as the result of...
Radio Telemetry as a Tool for Fisheries Mitigation
Monitoring discrete fixed locations requires automated receivers and data loggers while manned, mobile receivers are more suited to general movement or habitat studies. Of the three tagging...
Hydropower and Fish Passage Impacts
The Pacific Northwest Electric Power Planning and Conservation Act (Act) of 1980 formed the Northwest Power Planning Council, which establishes criteria and sets goals for developing future...
Regional Rivers Resource Assessment as a Tool for Hydropower Planning and Policy: The Pacific Northwest Rivers Study
In August, 1984, the Bonneville Power Administration (BPA) and the Northwest Power Planning Council (Council) initiated a study to provide information about important river characteristics...
Successful Behavioral Devices for Fish Protection
Since 1987, the Electric Power Research Institute (EPRI) has been sponsoring studies of behavioral barrier devices for protecting fish at hydroelectric facilities. Primary emphasis has...
Storing Sediment and Freeing Fish
When Mount St. Helens erupted in May 1980, it sent a river of pyroclastic ash and other debris into Washington's North Fork Toutle River Valley. The resulting debris pile...
A Case Study: Relicensing of Pensacola Hydropower Project
The current license for the Pensacola Hydropower Project (orginally licensed in 1939) will expire in 1988. The relicensing process for the project currently is underway. During the consultation...
Studies of Fish Protection Methods at Hydroelectric Plants
Five largely untested but economical fish-protection systems were tested at sites throughout North America. The process of selecting laboratory and field test sites was completed at the...
Development of Turbine Intake Downstream Migrant Diversion Screen
Prior to the spring of 1986 Public Utility District No. 2 of Grant County had developed a passive turbine intake screen design. A prototype of this design was placed in the emergency gate...
Protection of Juvenile Anadromous Fish
Protection of juvenile anadromous fish (salmon, steelhead, etc. ) during their seaward migration is a major concern in the Pacific Northwest. The existing screening structures at the head...
Influence of Three Sonic Devices on Fish Behaviour
Three sound emitting devices have been developed to control fish movement in the vicinity of generating stations. These devices have the advantage of increased flexibility in terms of...
Arbuckle Mountain Hydro Vertical-Axis Fish Screens
Fish screens to exclude small fry and debris at remote sites such as Arbuckle Mountain Hydroelectric Plant post unique design considerations to satisfy criteria established by fisheris...
