Historical ice jams and associated environmental conditions on Osoyoos Lake Historical ice jams and associated environmental conditions on Osoyoos Lake
Ice jams occur regularly at the southern outlet of Osoyoos Lake, which spans the border between the State of Washington and British Columbia, Canada. In recent winters, ice jams caused (1) decreases in downstream discharge that may adversely affect salmon spawning habitat and (2) short-duration lake-level rise that can interfere with lake level management agreements. In response, water...
Estimation of impounded sediment volume in the Similkameen River upstream of Enloe Dam, Okanogan County, Washington Estimation of impounded sediment volume in the Similkameen River upstream of Enloe Dam, Okanogan County, Washington
The Enloe Dam was built in 1920 for hydropower generation and impounds a steep-banked, narrow reach of the Similkameen River in north-central Washington. During the subsequent century, sediment from the Similkameen River watershed, which includes historical mining operations, accumulated within Enloe Dam’s impoundment. Enloe Dam ceased hydropower production in 1958 and is currently under
Lost in translation: Reconciling different streamflow permanence data products Lost in translation: Reconciling different streamflow permanence data products
The objective of this study is to provide a framework to reconcile streamflow permanence products that provide information on whether a stream is perennial or nonperennial. Accurate classification of streams as perennial or nonperennial is important for a variety of land and water resource management decisions. However, resource managers are challenged with how to reconcile different...

Watersheds and Fluvial Systems Team
The Watersheds and Fluvial Systems Team at the Washington Water Science Center provides reliable science to understand how watersheds, rivers, and streams function—and how they respond to a changing world. We aim to build partnerships that foster informed decision-making and effective resource management throughout the Pacific Northwest region and across the U.S.
Water Stargrass in the Lower Yakima River
The lower Yakima River faces water resource management challenges resulting from abundant water plant growth, negatively impacting water quality. New U.S. Geological Survey (USGS) research provides a deeper understanding of river conditions, informing resource management to protect this river and the communities it supports.
Remotely mapping stormwater facility footprints and storage volumes
Stormwater management practices are being used throughout the Chesapeake Bay watershed to reduce flood risks and pollutant loads, but consistent and comprehensive maps of these practices are often lacking. Stormwater managers often have incomplete information about the location and storage volume of stormwater facilities within their jurisdiction. Therefore, the USGS is working to develop...
