Quinault Groundwater
The Issue: Located on the north coast of Washington within the Queets-Quinault Watershed, the Quinault Indian Nation's coastal communities rely on groundwater as their sole source of drinking water. Climate change can directly affect groundwater throughout the watershed, particularly worrisome in vulnerable coastal aquifers. The Quinault Indian Nation will be collecting groundwater data for...
Mason County
The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in Mason County, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for groundwater. However, the quantity of usable groundwater, and the...
NAS Whidbey Transport Model
The Issue: The carcinogenic compound 1,4-dioxane was recently (2003) found in groundwater in the vicinity of the former landfill at Area 6, Operable Unit 1, Naval Air Station (NAS) Whidbey Island, Island County, Washington. The current extent and potential for further migration of 1,4-dioxane in the vicinity of Area 6 are not well known. Also at area 6, the Navy is exploring options to remove...
Little Spokane Hydrogeology
The Issue: Groundwater is an important resource for domestic, commercial, and agricultural usage in the Little Spokane River Basin, and groundwater discharge helps maintain streamflow in area streams. Consequently, as the population grows, and commercial and agricultural activity increase, so does the demand for groundwater. However, the quantity of usable groundwater, and the potential effects of...
Chamokane Framework and Model
Chamokane Creek Basin is a 179-square-mile area that borders and partially overlaps the Spokane Indian Reservation in southern Stevens County in northeastern Washington State. In 1979, all water rights in the Chamokane Creek Basin were adjudicated by a Federal court, which gave senior, reserved water rights to the Spokane Tribe of Indians for irrigation and protection of fish in Chamokane Creek...
Johns Creek Framework
Located in Mason County in western Washington State, Johns Creek is an important producer of coho and chum salmon. In 1984, the Washington State Department of Ecology established an Instream Resources Protection Program for Water Resource Inventory Area 14 (WAC 173-514) to retain sufficient in-stream flow to protect fish and wildlife, scenic, aesthetic and other environmental values. This program...
