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...

Skagit Ground Water Model

State and local water-resource managers in Lower Skagit/Samish Water Resource Inventory Area (WRIA-3) face two water-availability issues that are common throughout Washington State. First, they must reserve water for domestic wells that are exempt from the water rights system without harming river and stream ecosystems in the lower Skagit River basin. Skagit County, which would be responsible...

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...

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...
