Wastewater reuse may be detrimental to smallmouth bass abundance in the Shenandoah River Watershed
Issue: Municipal and industrial wastewater effluent is an important source of water for streams and rivers, especially during periods of low flow. The reuse of wastewater effluent may become even more important if climate change exacerbates low streamflow and drought conditions. However, wastewater effluent often contains chemicals that, when chronically present, can affect the health of aquatic...
Hydrologic, Water-Quality, and Ecological Monitoring and Analysis to Support Stream Restoration Research in Reston, Virginia
The U.S. Geological Survey, in cooperation with Resource Protection Group, Inc. is partnering with Reston Association to monitor the hydrology, water-quality, and ecology of two restored urban streams in Reston, Virginia – Snakeden Branch and The Glade. A combination of continuous and discrete hydrologic and water-quality data are collected to evaluate stream conditions and estimate sediment and...
River Continuum Concept Ecological Limit Functions for Fish and Benthic Data in Virginia
The ecological limit functions (ELF) developed in cooperation with the Virginia Department of Environmental Quality (DEQ) are a graphical representation of the current and historical state of aquatic biota in Virginia streams. The goal of this study was to quantify the potential species richness and habitat response to flow alteration using available long-term ecological data. Fish and benthic...
Shenandoah River Instream Flow Studies
As urban and rural growth continues, competition for clean water expands into stream areas previously capable of meeting local water-use demands. Conflicts among instream and offstream users of streamflow increase as flows decrease. This research enhances understanding of summer low-flow conditions in the North Fork, South Fork, and Shenandoah Rivers, relating water availability to physical...
South River Mercury Total Maximum Daily Load
The objective of the South River Mercury Total Maximum Daily Load (TMDL) study is to develop a better understanding of methyl mercury cycling in the South River and calculate mercury loading reductions that would protect fish from high mercury concentrations.
