The Economic Value of Trout Fishery Management Programs
The contingent valuation method is used to estimate the economic value of a trout fishing day at the Cache la Poudre River in Colorado. In addition, changes in daily economic value and...

Meeting Instream Flow Needs of Lower Colorado River in Texas
The Lower Colorado River Authority (LCRA), an agency of the State of Texas, manages the surface waters of the lower Colorado River in Texas. The major water supply source in the lower...

Managing Instream Flows for Salmonid Spawning Habitat
Detrimental sediment related effects on aquatic habitat for anadromous fisheries include (1) deposition of excessive amounts of fine sediments in spawning gravels, and (2) mobilization...

Managing Reservoir Storage for Instream Flow
Two possible approaches to using a portion of reservoir storage to supply instream flows are 1) to determine a fixed amount to be released each year as minimum instream flows and 2) to...

Natural, Cultural, & Environmental Resource Values Influencing Colorado River Basin Management
The Colorado River Basin supplies water to the seven western states of Wyoming, Colorado, Utah, Arizona, New Mexico, Nevada, and California, and to Mexico. Originally the Colorado River...

Wetland Engineering, Design, and Construction: State-of-the-Science and Research Needs
Local, state, and federal agencies, special interest groups, and individual landowners are undertaking wetland construction projects at a feverish pace to mitigate past and anticipated...

Juanita Creek Channel Restoration?King County, Washington
Juanita Creek, a small basin near Seattle that contains anadromous fish, was experiencing degradation due to urbanization. A detention pond and channel restoration improvements were constructed...

Use of Flood Control Features for Environmental Mitigation
The US Army Engineer District, Vicksburg (CELMK), plans to construct up to 167 water control structures, 52 confined disposal facilities, and 47 barrow pits as part of a major flood control...

An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...

Innovative Wetlands in Urban Settings Using Dredged Material
As a result of its work in the waterways of the nation, the U. S. Army Corps of Engineers (USACE) has restored or constructed wetlands using dredged material in a number of urban/suburban...

Innovative Wetland Re-creation in Urban Setting
The project site is a 106 hectare, mixed-used, commercial development east of Tampa, Florida and at the westerly limit of the town of Brandon, Florida. Delaney Creek traverses the site...

Water Temperature Issues in the 90's and Beyond
Temperature impacts are among the most common and most expensive environmental issues requiring mitigation at water projects. Several emerging environmental and regulatory concerns and...

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...

Development of Bioretention Practices for Stormwater Management
This paper introduces the concept of bioretention as an innovative stormwater quality management practice. Bioretention is a method to treat the first flush of runoff using a combination...

Design Considerations Associated with Bioretention Practices
This paper presents the design requirements of bioretention practices. Bioretention is a stormwater management practice using a combination of retention, native terrestrial vegetation...

Pollutant Removal Efficiency of Detention Basins
A simple method is presented for quick estimates of pollutant removal efficiency of detention basins under dynamic conditions. The method is based on the generalized solutions to the reservoir...

Long-Term Performance of Wet Detention Ponds
Wet detention is a technology which has been successfully applied in recent years to improve stormwater runoff quality in urban areas. Since most systems have a short operational history,...

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...

Water Quality Impacts from Development of Port Ludlow, Washington
Port Ludlow Bay is a tidal estuary located adjacent to Admiralty Inlet in Puget Sound, Washington. A planned development has been under construction along the bay since 1976. A 0.64 mgd...
