Yakima River Basin

The Yakima River flows 215 miles from the outlet of Keechelus Lake in the central Washington Cascades southeasterly to the Columbia River, draining an area of 6,155 square miles. The Yakima River Basin is one of the most intensively irrigated areas in the United States. Population in the Yakima River Basin was about 238,000 in 1990.

Columbia Plateau Groundwater Availability Study

The Columbia Plateau Regional Aquifer System (CPRAS) covers about 44,000 square miles of eastern Oregon and Washington and western Idaho. The primary aquifers are basalts of the Columbia River Basalt Group and overlying basin-fill sediments. Groundwater availability issues in the basin include: 1) widespread water-level declines caused by pumping, 2) reduction in base flow to rivers and...

Quilcene Bay

In response to concerns that increased use of ground- and surface-water supplies in watersheds in Washington leaves insufficient in-stream flow for fish and other users, the Washington State legislature passed the Watershed Management Act of 1998, which encourages watershed planning at the local level. As part of this planning, stakeholders within a Water Resources Inventory Area (WRIA) need...

Bainbridge Island

Ground water is the sole source of drinking water for the City of Bainbridge Island in Kitsap County, Washington. As the population grows, demand for ground water grows, too. However, because ground water is limited by area and by the potential for seawater intrusion, the City recognizes in the Water Resources Element of its comprehensive plan that water resources must be carefully managed and...

Lake Roosevelt-Upper Columbia River

Lake Roosevelt was formed on the Columbia River by the construction of the Grand Coulee Dam, and extends a total of 217 km to within 24 km of Canada The lake is heavily contaminated with trace elements that were discharged as slag material from a smelter in Canada; approximately 360 metric tons were discharged per day from 1900 to 1998. A study by the USGS reported that Lake Roosevelt bed...

RCMAP - Gunnison River at Spann Diversion at Gunnison, Colorado

The U.S. Geological Survey was engaged in a program to monitor and assess the long-term geomorphic behavior of selected river and stream reaches that previously had undergone some physical modification.  These modifications included natural channel adjustments to floods as well as intentional channel reconfigurations to alter the function or appearance of a river reach.

Virginia Chloride Monitoring Network

Objectives of the program are to (1) evaluate the spatial and temporal distribution of chloride concentrations in the aquifers, (2) evaluate the factors that affect the spatial and temporal distributions of chloride, and (3) assess the potential for upconing or lateral intrusion of saline water in the aquifers.

Flood Database for Colorado

The U.S. Geological Survey, in cooperation with the Colorado Department of Transportation, created a Web-based geodatabase for information on floods from 1867 through water year 2015 and information on paleofloods occurring in the past 5,000 to 10,000 years.  The geodatabase was created using Environmental Systems Research Institute ArcGIS JavaScript Application Programing Interface. Engineers...

Coastal Plain Culvert Study

Various environmental groups in Alabama are concerned that the use of culverts at highway crossings to convey stream flows has detrimental effects on the natural conditions of streams. Specifically, some groups are concerned that changes in stream geomorphology, sediment concentrations, and associated turbidity adversely impact the benthic macroinvertebrate community when culverts are...
