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...

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...
