The Simulation of Variable Release Temperatures from the Rock Creek-Cresta Project Using the USFWS Instream Temperature Model
Pacific Gas and Electric Company (PGandE) operates the Rock Creek-Cresta Project on the North Fork Feather River (NFFR) for hydroelectric generation under authority of Federal Energy Regulatory...
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...
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...
Downramping to Minimize Stranding of Salmonid Fry
The objective of this study was to develop a downramping regime for the Jackson Hydroelectric Project on the Sultan River in Washington that minimizes the stranding of juvenile salmon...
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...
Feasibility of Cold Water Releases from Lake Britton
The Pit River in Shasta County, California, is the site of the Pit 3, 4 and 5 Project, a major hydroelectric facility operated by the Pacific Gas and Electric Company (PGandE) under Federal...
Simulation of the Stanislaus Project: Performance of the U.S. Fish and Wildlife Service Instream Temperature Model on a Complex System
The primary objective of the study was to characterize the temperature regime of the MFSR Middle Fork Stanislaus River and determine the effect of alternate release flows on stream temperature...
The Council's Strategy for Improving Fish Passage
The Columbia River Basin Fish and Wildlife Program was developed by the Northwest Power Planning Council in 1982 and amended in 1984 and 1987. The program is likely the largest ongoing...
A Juvenile Fish Bypass Program at Columbia River Basin Projects
Hydroelectric development in the Pacific Northwest region has altered the natural flow of the Columbia River and its major tributary, the Snake River. This has proven to be detrimental...
Systems Analysis for Fisheries Protection and Mitigation at Corps of Engineers Columbia River Dams
Pacific Northwest anadromous salmon and steelhead that migrate to and from the ocean are greatly affected by the numerous Columbia and Snake River dams they have to pass, first downstream...
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...
Managing for Multiple Uses?Theory and Practice
One of the gratest challenges given to reservoir operators is to provide an operating regime that will accomplish the objectives for which the project was constructed. This is important...
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...
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....
Hydropower Development of China's Yangtze River
The Yangtze has eight times the hydro potential of the Columbia River basin, currently the largest developed hydro system in the world. In order to pursue economic development through...
Hydrologic Studies for Dinkey Creek Hydro-Electric Project
The economic analysis and final design of the 120 MW hydro-electric development on Dinkey Creek, a tributary of the North Fork of the Kings River in the Central Valley of California, requires...
Estimating Streamflow Characteristics for Micro-hydro Sites in Northwestern Oregon
Assessing hydropower potential requires knowledge of the streamflow characteristics at prospective sites. Gaging stations are often unavailable. A method for estimating streamflow characteristics...
The Role of Headwater Benefits in Hydropower Planning
Headwater benefits are the power benefits that accure to owners of downstream hydroelectric plants as a result of the operation of headwater improvements. The retention of water in upstream...
The Effect of Sedimentation on Hydro-Developments
This paper will discuss two major impacts which are the hydro construction on natural stream sedimentation and the sedimentation related problems during hydro operation. The two types...
