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...

Salmon Creek Basin

Two reservoirs in the Salmon Creek Basin in north-central Washington store runoff from the upper basin for out-of-basin irrigation of farmlands. The U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation (Reclamation), developed a precipitation-runoff model that simulates historical daily unregulated streamflows for different locations in the Salmon Creek Basin. The model...

Elwha River

The formerly free-flowing Elwha River was famous for the diversity and size of its salmon runs. After the construction of the Elwha Dam (1912) and the Glines Canyon Dam (1927), fish lost access to more than 70 miles of mainstem river and tributary habitat. As a result, all 10 runs of native Elwha salmon and sea-going trout declined sharply. Restoration of the Elwha River ecosystem will be...

Nooksack River Ground-Water Bacteria

The lower Nooksack River Basin is located in Whatcom County, in the northwestern part of Washington. Within areas of the basin, the ground-water aquifer is shallow. Knowledge of how the surface water and the aquifer interact, and how this interaction affects the transport of bacteria and nitrates from agricultural fields to the ground-water system, is important to residents of the basin. This...

In the past, levees have been built along the river banks of the Puyallup River to prevent floodwater from damaging roads, buildings, farms, and other areas in the floodplain. Because levees can worsen flooding by creating backwater effects or reducing floodplain storage, Pierce County is planning to remove current levees and build new ones further away from the river channels.

Water Resources of the Tulalip Indian Reservation

Future increases in population and development of the Tulalip Indian Reservation and neighboring areas would lead to increased pumping of ground water both on and off the Reservation. Increased pumpage in coastal and inland wells may decrease baseflows of streams and could affect fish-rearing operations in the Tulalip Creek watershed.
