Lake Crescent Cover
Date Published: January 6, 2011
Status: Completed

Lake Crescent

Lake Crescent in Olympic National Park is known for its clear, near-pristine water. Because the water is very low in plant nutrients, such as nitrogen and phosphorus, the lake is extremely susceptible to even small increases in nutrient levels, which could cause algal blooms and impact the health of three species of fish in the lake. Currently, the growth of bottom-dwelling algae in developed...

Columbia Plateau Groundwater Availability Study

The Columbia Plateau Regional Aquifer System (CPRAS) covers about 44,000 square miles of eastern Oregon and Washington and western Idaho. The primary aquifers are basalts of the Columbia River Basalt Group and overlying basin-fill sediments. Groundwater availability issues in the basin include: 1) widespread water-level declines caused by pumping, 2) reduction in base flow to rivers and...

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...

Benthic invertebrates and periphyton in the Elwha river basin: Current conditions and predicted response to dam removal

The impending removal of two dams on the Elwha River in Washington State offers a unique opportunity to study ecosystem restoration at a watershed scale. We examine how periphyton and benthic invertebrate assemblages vary across regulated and unregulated sections of the Elwha River and across different habitat types, and establish baseline data...

Decreased mortality of lake michigan chinook salmon after bacterial kidney disease challenge: Evidence for pathogen-driven selection?

In the late 1960s, Chinook salmon Oncorhynchus tshawytscha from the Green River, Washington, were successfully introduced into Lake Michigan. During spring from1988 to 1992, large fish die-offs affecting Chinook salmon occurred in the lake. Multiple ecological factors probably contributed to the severity of the fish kills, but the only disease...

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)...
