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...

Upper Kittitas County

The Issue: Baseflows in the tributary streams in the western portion of Kittitas County are important in the late summer and fall when demands on these streams peak. An ongoing USGS Yakima River basin study indicates that groundwater and surface water are interconnected, however the hydrogeologic framework and the potential impacts of groundwater withdrawals on tributary streamflow in the...

Recharge and frozen ground in the PNW

The Issue: Seasonally frozen ground occurs over approximately one-third of the contiguous United States, and the extent and duration of frozen ground have been decreasing as a result of global warming. In semi-arid regions such as the Columbia Plateau and Snake River Plain in the Pacific Northwest, nearly all natural recharge occurs between October and March when intermittent...

Nooksack River Streamflow and Network Analysis

The Lummi Nation is partner to six USGS streamflow-gaging stations in the Nooksack River basin that measure streamflow in small streams. The Lummi Nation uses data from these stations to help manage its natural resources and has requested that the USGS analyze the available data record. As a result, the USGS is using streamflow data collected in and near the Nooksack River basin to develop...

Vancouver Lake Nutrient Budget

The Issue: Vancouver Lake in Clark County, WA has been experiencing water quality problems for decades. Recently, harmful algal blooms have been taking place in summer resulting in closures of the lake to swimming/water contact. One potential cause of these algal blooms in the increased loading of nutrients to the lake; however, there is currently little known about the amount and timing of...

Clackamas River Basin Water-Quality Assessment

Starting in 1997, the USGS began routinely studying water resources in the Clackamas River Basin. Whether it be assessing harmful algal blooms, runoff issues, streamflow, or watershed health, the USGS has worked with its partners to maintain one of Oregon's most beloved rivers.

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...

Sources of Mercury in Sinclair Inlet Project

The sediments in Sinclair Inlet within Puget Sound, Washington have elevated concentrations of a number of organic compounds and elements including mercury. Following remediation actions under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), it was determined that there is insufficient information to determine whether remedial action taken at OU B Marine with...

Cedar River Peak Flow Management

The Cedar River watershed provides two-thirds of the water supply for the greater Seattle metropolitan region, in addition to being home to numerous federally listed salmon species. The City of Seattle, through Seattle Public Utilities (SPU), works closely with the Cedar River Instream Flow Commission (IFC) to adaptively manage flows on the Cedar River. Seattle operates its water management...

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...

Phosphorus SPARROW Model for the Yakima River

The Issue - During the 2004-07 irrigation season, nutrient concentrations in the lower Yakima River were high enough at certain times and locations to support the abundant growth of periphytic algae and macrophytes which resulted in large daily fluctuations in dissolved oxygen concentrations and pH levels that exceeded the Washington State water-quality standards for these...

Chimacum GW Model

Projected increases in population and development in northeastern Jefferson County, Washington, are expected to lead to increased groundwater withdrawals in the Chimacum Creek Basin. Changes in land use and climate could reduce groundwater recharge, thereby reducing groundwater available for drinking and for baseflow to streams that host endangered fish species.

The USGS is developing...
