White River Basin and Lake Tapps Water Quality
The Issue: Water diverted from the upper White River to maintain water levels in Lake Tapps impacts flows and fish resources in the White River. In the lower White River, releases of warm water from Lake Tapps for hydropower generation frequently lowered concentrations of dissolved oxygen and increased water temperatures at river mile 1.8. In the White River diversion reach, has segments that are...
Linking Sources to the Sound
The Issue: Bioaccumulation of toxic chemicals in freshwater and marine aquatic research in the Puget Sound continues to be a concern for environmental managers and general public. With renewed interest, Washington State Department of Ecology (https://www.ecy.wa.gov/programs/wq/pstoxics/) began a phased, coordinated effort in 2006 to understand the sources and management options in controlling the...
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...
FEMA High Water Marks - Western Washington Flood, January 2009
The Issue: Significant flooding occurred throughout western Washington on January 7 and 8, 2009. As part of its Hazard Mitigation effort, the Federal Emergency Management Agency (FEMA) Region X needs documentation on the extent of flooding for verifying Preliminary Digital Flood Insurance Rate Maps (DFIRMs) and corresponding Flood Insurance Studies (FIS) that have been recently completed, or are...
Moses Lake Sediment
Located in central Washington, Potholes Reservoir is a key feature of the Columbia Basin Project and serves as a vital source of irrigation water. Potholes Reservoir has traditionally been fed water through the East Low Canal, but due to operational changes over the years, the Bureau of Reclamation is looking for reliable alternatives to ensure an adequate portion of water supply to Potholes...
Lower Bonaparte Springs
The Issue: The Confederated Colville Tribes are concerned with maintaining and enhancing endangered summer steelhead fish stocks in the Okanogan River and its tributaries. One Okanogan River subbasin of particular interest is Bonaparte Creek where almost 50 percent of the summer steelhead captured in 2008 were of natural rather than hatchery stock. The Colville Tribes are working to ensure enough...
FEMA Technical Support
9722-DRE00 - FEMA Technical Support, Pre-Declaration, January 2009 Floods - Completed FY2009 A wide plume of warm moist air streaming in from west of Hawaii caused widespread rainfall throughout western Washington in early January 2009. National Weather Service flood stages were exceeded in many different basins, most of which drain from the west side of the Cascade Range. Flows at four long-term...
Navigability Potential of Washington Rivers
U.S. Geological Survey (USGS) developed a method to map the navigability potential of Washington rivers using physical characteristics of river channels. The work supported efforts by the Washington Department of Natural Resources (DNR) to determine which rivers are navigable and fall under state ownership. According to the Washington State Constitution (Article XVII, Section 1), the state claims...
Potholes Reservoir
Managed by the U.S. Bureau of Reclamation (USBR), water is diverted from the Columbia River into Potholes Reservoir and the canal system for delivery to irrigators. Through the USGS/USBR collaborative Watershed and River Systems Management Program (WARSMP), the USBR will be developing a river-management model to improve the efficiency of water distribution. An important input needed for the model...
Mid-Columbia Habitat Project
To meet their dam licensing agreements, operators of privately owned dams are required to offset the unavoidable loss of endangered salmon passing the dam by restoring and enhancing streams and providing hatcheries. Finding suitable side channels is made difficult by subtle features and overgrowth. To help the Mid-Columbia Tributary Committee identify sites for restoration and enhancement and...
Eastbank Aquifer near Rocky Reach Dam
Ground water from the Eastbank Aquifer system in north-central Washington is a regional water supply for about 50,000 people, as well as for a fish hatchery operated by the Chelan County Public Utility District (PUD). The fish hatchery compensates for salmon and steelhead lost in the operation of two hydroelectric projects on the Columbia River owned by the PUD. The fish hatchery needs relatively...
Yakima River Temperature Model
In the Yakima and Naches Rivers, water temperature is often a limiting factor in the survival of salmon during spawning and rearing. The Bureau of Reclamation uses a computer model to assess the effects of reservoir-management scenarios on temperatures and the success of salmon restoration. To provide the daily maximum and long-term water temperature data needed by the model, the Bureau of...
