Surface Water Modeling and Analysis

In order to understand complicated surface-water networks within a basin and conduct different land-planning scenarios that affect the hydrology of the system, computer models need to be constructed to account for all the variables in the water budget such as rainfall and evaporation and the effects of the land surface and soils on the timing and amount of runoff.  These rainfall-runoff or watershed models use the comparison of observed runoff against simulated runoff to calibrate and validate the model.  Hydraulic models examine channel geometry and channel features to simulate river channel velocity and stage for a given river discharge.  These models are often used in flood-hazard studies and habitat analysis.

Analysis of USGS Surface Water Monitoring Networks

The issue: National interests in water information are important but challenging to incorporate into planning and operation of a monitoring network driven by local information needs. These interests include an understanding of the spatial variability in water availability across the United States, anthro-physical factors including climate and land use that affect water availability, and federal...

Water use

The Issue: Comprehensive water-use data and analysis of water-use information are needed to quantify the stress on existing supplies and to better model and evaluate possible water-supply management options to supplement traditional water-supply approaches. Advances have been made in the ability to control, divert, and develop water, but little attention has been paid to keeping accurate accounts...

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 channelized...

NWIFC Water Assessment

Water resources are essential to Native American Tribes in western Washington for instream and out-of-stream uses. As the demand for water across the region increases, western Washington Tribes need critical information about water availability, water use, and ecological needs for water in order to manage their resources. To assess tribal water resources comprehensively in western Washington, the...

Hood Canal

In September 2002, fish in Hood Canal near Hoodsport were under stress from low concentrations of dissolved oxygen, prompting the Washington State Department of Fish and Wildlife to temporarily close parts of Hood Canal to some types of fishing during the month of October. In 2003, low dissolved oxygen conditions worsened, some fish kills were observed as early as June, and by October large fish...

Navigable Rivers in Washington

Determining whether a stream or river in Washington is "navigable" is important because it helps establish state ownership of the "bed and shore" of navigable waterways as stated in the Washington State constitution. State-owned lands are managed by the Washington State Department of Natural Resources. Because the constitution does not explicitly define what criteria should be used to determine...

Potholes Reservoir

Managed by the U.S. Bureau of Reclamation (USBR), water is diverted from the Columbia River into Potholes Reservoir and the canal system for delivery to irrigators.Through the USGS/USBR collaborative Watershed and River Systems Management Program (WARSMP), the USBR will be developing a river-management model to improve the efficiency of water distribution.

Salmon Creek Basin

Two reservoirs in the Salmon Creek Basin in north-central Washington store runoff from the upper basin for out-of-basin irrigation of farmlands. The U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation (Reclamation), developed a precipitation-runoff model that simulates historical daily unregulated streamflows for different locations in the Salmon Creek Basin. The model can...

Puyallup Streamflow Trends

Covering about 28 square miles along the lower reaches of the Puyallup River in Pierce County, the Puyallup Indian Reservation is located in the lowest part of the basin. For this reason, all water-related activities in the basin affect the Puyallup Tribe of Indians' water resources and fish.Because of their important links to the Puyallup River, the Puyallup Tribe of Indians want to know more...
