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...
Urbanization alters riverine fluorescent dissolved organic matter characteristics in a forested city – metropolitan Atlanta, Georgia (USA) Urbanization alters riverine fluorescent dissolved organic matter characteristics in a forested city – metropolitan Atlanta, Georgia (USA)
Streams and rivers in urban watersheds are predicted to export more bioreactive, autochthonous dissolved organic matter (DOM) relative to forested watersheds. However, the spatial and temporal variations of DOM quality in forested urban watersheds remain uncertain, and their relationships with socioeconomic conditions, biological characteristics, and the built environment are...

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...
Testing non-contact discharge measurement methods in the Nooksack River
The Issue: The North Cedarville streamgage on the Nooksack River (USGS 12210700) is critical for flood monitoring and hazard assessments. However, making discharge measurements at high flows, which are necessary to maintain an accurate stage-discharge relation at this dynamic site, is complicated by transport of woody debris and difficulties detecting the bed using traditional acoustic doppler...
