Puget Parks

Snow and ice are major sources of water for plants and animals in the parks and forests of the Puget Sound Basin, including Olympic, North Cascades, and Mt. Rainier National Parks, and Mt. Baker-Snoqualmie and Olympic National Forests. In the North Cascades National Park alone, there are more than 300 small glaciers that feed 245 mountain lakes and a myriad of streams, wetlands, and aquifers....

GW/SW Interactions

Knowing the interactions of ground water and river water can help reduce the fluctuation of water supplies in alluvial (sediment-deposit) river basins.

To develop general principles of these interactions in order to identify and analyze them, the USGS is reviewing the results of the numerous studies of these interactions in Pacific Northwest basins. The review will describe common...

Columbia Basin GWMA

More than 80 percent of drinking water in the mid-Columbia Basin comes from ground water. In Adams, Franklin, and Grant Counties, nitrate concentrations in water from about 20 percent of all drinking-water wells exceed the U.S. Environmental Protection Agency maximum contaminant level for nitrate. The three counties jointly formed the Columbia Basin Ground Water Management Area (GWMA) in...

GW Recharge

Hydrologists increasingly rely on computer watershed models to estimate groundwater recharge from precipitation on a regional scale. The model parameters used in simulations of recharge are various climatic, hydrologic, and physical characteristics of a watershed or stream basin. To date, the watershed models have not been evaluated to determine which model parameters are the dominant controls...

Lake Whatcom

Lake Whatcom, a large, natural lake in Whatcom County, is a source of drinking water for about 86,000 in the Bellingham area and a place for recreation. Elevated levels of mercury have been found in fish and sediment sampled from the lake. Possible sources of the mercury include atmospheric deposition, tributary discharges, landfills, dumpsites, and local mining operations.

Columbia Basin Irrigation

The National Marine Fisheries Service (NMFS), in its 2000 Biological Opinion for the Columbia Basin Irrigation Project (CBIP) in eastern Washington, asked for a determination of whether pesticides are present in irrigation return flows at levels that may harm or adversely affect salmon and steelhead species listed for protection under the Endangered Species Act. As the major resource manager...
