Sacramento and Trinity River Systems: A Demonstration of River Temperature Management for the 90's
Drought in Northern California resulted in the potential that summer and early fall, 1992, Sacramento and Trinity River temperatures would exceed critical levels for sustaining salmon...
Biological Modeling in the Columbia Basin: An Organized Approach to Dealing with Uncertainty
Development of the Columbia River basin has had a profound impact on its natural resources, particularly species of Pacific Salmon. Passage of the Northwest Power Act of 1980 put in motion...
Managing Snake River Operations for Juvenile Salmon Migration
A simulation model of Snake River hydrology and water management institutions has been developed. The model was used to investigate management changes to enhance flow conditions for migrating...
Columbia River System Operations ? Water Quality Assessment
In mid-1990, the U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, and Bonneville Power Administration embarked on a Columbia River system operation review. Ten technical work...
Snake River Salmon Recovery Plan Development
The process used by the Snake River Salmon Recovery Team to develop its recovery plan is described. Major conditions affecting fish survival are identified. The Team's approach to evaluate...
Columbia River Basin Fish and Wildlife Program Strategy for Salmon
Three species of Snake River salmon have been listed as threatened or endangered under the federal Endangered Species Act. In response, the Northwest Power Planning Council worked with...
Snake Reservoir Drawdown ? A Brief Progress Report
The Northwest Power Planning Council has directed the region to employ the use of 'Drawdown' as tool to help threatened and endangered salmon stocks in Snake and Columbia rivers unless...
Role of Economics in Endangered Species Act Activities Related to Snake River Salmon
The development of recovery actions for the species of Snake River Salmon listed under the Endangered Species Act (ESA) must consider a wide range of actions covering the different life-cycles...
Impacts of Hydropower Operation on Water Supply from Lower Colorado River in Texas
The Lower Colorado River Authority (LCRA) of Texas is both a water and energy supplier to a large area of Central Texas. LCRA generates approximately 10 percent of its power from hydroelectric...
The Development and Use of Policy Statements in River Simulation Models
There are a number of ways in which the physical operation of a river system can be expressed in simulation models. Most of the earlier simulation models have incorporated the operating...
The Law of the River: Policy Expression
The need to accurately represent the law of the Colorado river has heretofore precluded the use of any general purpose river basin simulation model. In order to overcome the inflexibility...
Object-oriented River System Simulation
This paper describes an object-oriented approach to river basin simulation modeling that is event driven rather than time driven as in most river system simulation models. At the heart...
RSS: A Construction Kit for Visual Programming of River Basin Models
With the ever increasing pressure on environmental resources, there exists strong interest in river basin models which can be used to simulate proposed policy alternatives. Traditionally,...
Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...
Water Marketing in Washington?The Next Step?
The state of Washington has been blessed with an abundance of water resources for its use, including the Columbia and Snake rivers, but with the listing of the Snake River Sockeye Salmon...
Real-Time Water-Control System for the Trinity River, Texas
To provide information for improved flood prevention and control in the Trinity river basin in Texas, we developed a real-time water-control system that (1) retrieves rainfall and streamflow...
Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...
Impacts of El Ni?o in Western Washington
The climatic phenomenon called El Nino is described, and its impact on hydrologic conditions in western Washington is shown for two recent events. Impacts on water management during the...
The Potomac Experience?A Forerunner of DPS
Thirty years ago, dramatic events were about to begin in Potomac River basin with the publication of a report of study recommending 16 major reservoirs and hundreds of small ones to solve...
The Challenges of Interstate Water Planning and Management
This study is one of four primary basin studies as part of the U.S. Army Corps of Engineers National Study of Water Management During Drought, a four year study initiated after the Drought...
