Kitsap Groundwater Model

The Issue: Groundwater provides a major source of drinking water for the population of the Kitsap Peninsula. Consequently, as the population grows, so does the demand for groundwater. However, the quantity of usable groundwater is limited, largely because the Peninsula is bounded by seawater and the potential for water-level declines and seawater intrusion increases as groundwater usage...

Raging River Temperature

The Issue: Large, in-channel wood that helps to create and maintain healthy aquatic habitat in rivers throughout the Pacific Northwest was removed from many rivers in the past. In 2009, King County put wood back into the river to restore the Raging River watershed. To guide the county's restoration of the Raging River watershed, managers need to know the effect of restoration...

Lake Spokane

The Issue: Phosphorus from many different sources has caused water quality problems for Lake Spokane in eastern Washington by promoting the growth of algae and aquatic plants. Phosphorus comes from municipal and industrial point-sources upstream of Lake Spokane, as well as non-point sources like septic tanks, agricultural fields, and wildlife. Lake Spokane was listed by the...

South Fork Nooksack River Basin Groundwater and Surface-water Interactions and Processes

High water temperatures and low instream flows during the summer have been identified as some of the key limitations for the viability of South Fork Nooksack River salmon populations including summer and spring-run Chinook salmon. Restoration strategies including the placement of engineered log jams, the restoration of floodplains and wetlands, and instream flow negotiation have been developed...

White River Bioenergetics

The White River Basin is located in western Washington and drains an area of about 500 square miles. Rivers in the White River Basin are fed by melt water from glaciers on Mt. Rainier, runoff from snowmelt and rain, and groundwater discharge. Beginning in the early to mid-twentieth century, the White River from river mile (RM) 9 to its confluence with the Puyallup River was extensively...

Water velocity, turbulence, and migration rate of subyearling fall Chinook salmon in the free-flowing and impounded Snake River

We studied the migratory behavior of subyearling fall Chinook salmon Oncorhynchus tshawytscha in free-flowing and impounded reaches of the Snake River to evaluate the hypothesis that velocity and turbulence are the primary causal mechanisms of downstream migration. The hypothesis states that impoundment reduces velocity and turbulence and alters...
