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...

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...

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...

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.

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...

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.

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).

Predicting recolonization patterns and interactions between potamodromous and anadromous salmonids in response to dam removal in the Elwha River, Washington State, USA

The restoration of salmonids in the Elwha River following dam removal will cause interactions between anadromous and potamodromous forms as recolonization occurs in upstream and downstream directions. Anadromous salmonids are expected to recolonize historic habitats, and rainbow trout (Oncorhynchus mykiss) and bull trout (Salvelinus confluentus)...
