Water Resources Inventory Area 1 Watershed Management

In recent years, increased use of ground- and surface-water supplies in watersheds of Washington State has created concern that insufficient in-stream flows remain for fish and other users. In response, the Washington State legislature passed the Watershed Management Act of 1998 (ESHB 2514; see also Ch.90.82 RCW - Watershed Planning), which encourages and provides some funding for local...

Cedar River Watershed

The Cedar River watershed provides two-thirds of the water supply for the greater Seattle metropolitan region, in addition to being home to numerous terrestrial and aquatic organisms such as salmon, some of which are Federally listed as threatened species. The City of Seattle is establishing monitoring plans for the Cedar River watershed to effectively manage the resource. A critical component...

Puget Sound-Willamette Trough

More than 70 percent of the population of Washington and Oregon resides in the Puget Sound-Willamette Trough, which stretches north-south on the western side of the Cascade Range. The area is one of the principal regional ground-water systems in the Nation, but little is known about the quantity and quality of the ground water, the regional flow system, or the interaction of the system with...

Puyallup Flood Alert

The Puyallup River Basin lies mostly within Pierce County, Washington, and contains 972 square miles of land ranging in elevation from zero at its mouth in Puget Sound to 14,408 feet at the top of Mount Rainier. The cities of Tacoma, Puyallup, Sumner, and Orting are some of the population centers located in the basin.

To protect lives and property in the basin, Pierce County needs...

Highway Storm-Water Detention

In some areas of the state, the Washington State Department of Transportation (WSDOT) sometimes directs the storm-water runoff from highways into detention basins that store the water until it infiltrates into the ground. Because most of the water eventually percolates to the water table, and because runoff from highways can contain contaminants, using roadside detention basins may degrade...

Elwha-Morse Watershed

Have increased demands for Washington State's ground water and surface water left sufficient stream flows for fish and other uses?

To find out, the state's Watershed Management Act of 1998 (ESHB 2514) confers on local people the responsibility for conducting local watershed planning.

The Elwha-Morse Watershed area was formed out of the western part of Water Resources Inventory...

Pierce County Groundwater

The rapid growth of population in the Tacoma-Puyallup area in Pierce County has placed increasing demands on the ground-water resource. Most domestic water needs are met by wells completed in the several hundred feet of glacial deposits that underlie the area, and about 9,000 persons are served by a single spring on the southwestern side of Puyallup. Most of the population relies on individual...

Probability Flows for Streams in Eastern WA

Under Washington regulations, bridges, culverts, and other stream-crossing structures need to be designed with fish passage in mind. For culverts, maximum flows cannot exceed a 10-percent exceedance probability flow (the flow that is equalled or exceeded 10 percent of the time) when fish are migrating upstream.

To help the Washington Department of Natural Resources manage its culverts...

Lightning Creek at Clark Fork, Idaho: December 9, 2015

On December 9, 2015, heavy rain and resulting snowmelt swelled many Pacific Northwest rivers to flood stage. One of these streams was Lightning Creek at Clark Fork, Idaho. In a 24-hour period, Lightning Creek rose from about 200 cubic feet per second (cfs) to more than 10,000 cfs as recorded at USGS strreamgage 12392155.

Idaho's water-quality managers have a new tool to help them estimate whether water flows in any given stream year-round or only intermittently.
The tool-a geospatial model-applies statistical equations that feed information into a geographic information system (GIS) map similar to the Web-based street maps most people are familiar with.

Fifteen fishers were released yesterday within the Skokomish, Hoh, and Queets valleys of Olympic National Park, bringing the total number of reintroduced animals to 47. Access limitations caused by recent snow and floods created logistical challenges for the people involved, but apparently not for the fishers as they bounded from their cages and ran into the forest.

The Willamette, a large river associated with 70 percent of the population of Oregon, is getting cleaner in regard to some persistent toxic pollutants that are a legacy of past management practices. A 257-mile portion of the Columbia River between Umatilla, Oregon, and Skamokawa, Washington, is also showing a similar trend.
