Ghost Development, owned and operated by TransAlta Utilities, is near the eastern margin of the Rocky Mountain Foothills, approximately 33 km northwest of Calgary, Alberta. The development...
Licensing the Moose River Hydroelectric Project
This paper describes environmental considerations in the licensing and permitting of the Moose River Hydroelectric Project, a 12.2 MW development in Central New York State. It illustrates...
FERC's Experience in Analyzing Cumulative Impacts
Since the mid-1980's, the Federal Energy Regulatory Commission (Commission) has assessed cumulative impacts associated with developing proposed hydropower projects. A brief...
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...
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...
A Water Quality Impact Analysis of a Hydropower Facility
A low-head hydropower generating facility has been proposed at an existing dam site on a river. The state environmental agency has required an environmental evaluation into the potential...
Balancing Hydropower Development in the Ohio River Basin
A large number of retrofit hydroelectric projects have been proposed at existing navigation dams in the Ohio River basin. These proposals involve potentially adverse environmental impacts,...
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...
