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...

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...

Effects of Selective Withdrawal and Hypolimnetic Releases on Downstream Fish Resources
Selective withdrawal (multilevel outlet) structures on dams can be operated to modify reservoir discharges with the goal of improving downstream water quality and fish resources. A study...

An Approach to Addressing Interactive Effects of Multiple Hydro Projects in a River Basin
Cumulative effects issues continue to arise, not only related to multiple small hydro projects, but also to multiple relicensing of major projects, development of multiple projects at...

The Role of Hydrologic Forecasts and Water Management in Support of Fisheries Enhancement
With the passage of the Pacific Northwest Electric Power Planning and Conservation Act of 1980 and the adoption of the Columbia River Basin Fish and Wildlife Program in 1982, a new mandate...

Cumulative Impact Assessment: Issues to Consider in Selecting a Cumulative Assessment Method
Because widespread interest in the subject is new, there are no standard or generally recognized methods for cumulative impact assessment. A method should include procedures for (1) evaluating...

Cumulative Impact Assessment: Application of a Methodology
The authors expanded upon the Federal Energy Regulatory Commission's (FERC) Cluster Impact Assessment Procedure (CIAP) to provide a practical methodology for assessing potential...

Field Experiences in Improving Water Quality Downstream From Dams
Recent experiences by the Tennessee Valley Authority in improving water quality and fish habitat downstream from dams are presented. At Douglas Dam, floating pumps near the surface of...

Reservoir Releases Improvements?Requiem for Integrating Pollution Control and Resource Management Programs?
To better define the interrelationships between economic growth and development, pollution control, and water resource management, TVA conducted two studies that examined how reservoir...

Instream Flow Values and Power Production
An approach relating the value of water instream to water flow in the stream results in a continuous function of value versus flow. This function is developed using the Physical Habitat...

Project Alternatives to Benefit Endangered Species
In April 1986, the Missouri River Division, U. S. Army Corps of Engineers, determined that operation of the main stem system had the potential to adversely affect the listed species. Consultation...

Instream Flow Methodologies and Requirements
Instream flow is a term applied to the discharge occurring downstream from and at least partly controlled by a dam or diversion structure. The volume and timing of instream flows most...

Glen Canyon Environmental Studies Resource Response Analysis
The primary objective of the Glen Canyon Environmental Studies is to determine how the resources of the Grand Canyon respond to the operations of Glen Canyon Dam. Two levels of analysis...

Bio-Economic Models for Measuring the Economic Effects of Hydropower on Anadromous Fish Populations in the Pacific Northwest
An empirical model is presented for predicting the net economic value of changes in recreational catch of salmon and steelhead in Oregon, Washington and Idaho associated with construction...

Water Management for Juvenile Fish Passage
The regional goal of restoring upriver runs of adult salmon and steelhead requires increased survival of the juvenile fish migrating to the ocean. Juvenile fish survival requires: (1)...

Determination of Values of Project Storage for Hydropower Scheduling
The Columbia River is characterized by multiple and sometimes conflicting uses, and its basin extends over many political jurisdictions. To balance pluralistic needs and authorities with...

Marketing Power in the Pacific Northwest
The marketing of power in the Pacific Northwest is a process intimately tied to the management of the Columbia River system. This paper describes the characteristics of the river and transmission...

Columbia River Treaty Perspectives
The Columbia River Treaty was signed in 1961 and ratified by the governments of Canada and the United States in 1964. The Treaty required British Columbia to construct three large storage...

Reservoir Regulation in the Monsoon Climate of Korea
An examination of reservoir regulation rules in light of uncertain estimates of river flow in the Han River Basin, Republic of Korea, shows that two strategies will improve total hydroelectric...

Simulation of Irrigation and Reservoir Water Use
Computer simulation of irrigation water use and corresponding downstream reservoir operation has been developed for the Canyon Ferry Reservoir on the Missouri River in Southwestern Montana....
