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...

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...

WSDOT Stormwater Monitoring

The Washington State Department of Transportation, or WSDOT, monitors the water quality of runoff from state highways and other transportation facilities under their National Pollution Discharge Elimination System (NPDES) permit. The NPDES permit requires WSDOT to make sure that the stormwater meets Clean Water Act and other regulations designed to restore and protect our country's water...

Navigable Rivers in Washington

Determining whether a stream or river in Washington is "navigable" is important because it helps establish state ownership of the "bed and shore" of navigable waterways as stated in the Washington State constitution. State-owned lands are managed by the Washington State Department of Natural Resources. Because the constitution does not explicitly define what criteria should be used to...

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...

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...

Green River Geomorphic Responses

In the Pacific Northwest, water, sediment, and vegetation primarily determine the form of large river channels and shape their ecosystems. Dams on rivers affect all of these elements, with consequences for habitats and aquatic species. Understanding how water, sediment, and vegetation interact in habitats is key to managing rivers. In the case of the middle Green River in King County,...

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...

DOH Nitrates

Ground water is a significant source of drinking water in Washington State, and keeping it free of contamination is important for public health. Public supply wells are frequently tested for nitrate concentrations, but private wells are tested only when they are drilled. This limits information about the potential exposure to elevated nitrate concentrations in private wells.

To help the...

San Juan County

Aquifers of the San Juan Islands, which are the principal source of fresh water, are commonly intruded by seawater at near-shoreline locations (less than one mile from the shore). Because the demand for ground water has escalated in recent years due to population growth and is expected to continue, the progression of seawater intrusion and areas most susceptible to future seawater intrusion...

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...
