Project Abstract:
Maintaining the appropriate quantity, timing, and quality of water in our nation’s rivers and streams is important because the survival and reproduction of wildlife species are tightly linked to specific water flow conditions. Altered flows can decrease or increase water levels and affect water quality and water temperature. This can lead to loss of wildlife species. Water availability for agricultural, municipal, industrial, and recreational use can also be reduced. This project will have U.S. Geological Survey (USGS) and U.S. Environmental Protection Agency (EPA) scientists develop regionally consistent streamflow metrics and measures of streamflow alteration, as well as an online mapping tool to identify areas where streamflow alteration is highest at the regional, state, or watershed scale. The Baseline Flow, Gage Analysis & On-Line Tool will help scientists prioritize restoration efforts. Additionally, for a large focus-area watershed in Mississippi, a streamflow accounting tool will be created to enable water resource managers to evaluate a range of potential management scenarios. This project involves installation and operation of up to 18 new streamgages, structures containing instruments to measure and record the amount of water flowing in a river or stream, or its discharge. These streamgages will create a more robust monitoring network and will help to minimize flow alteration predictions in future analyses. The new streamgages will improve future streamflow assessments by targeting areas and land cover types currently underrepresented in existing monitoring networks. The USGS has requested $5.5M and EPA has requested $300,000 for their parts of the project.
