Streamflow alteration impacts fish diversity in local rivers
Date:1/16/2014

A new USGS study quantifies change in fish diversity in response to streamflow alteration in the Tennessee River basin.

The USGS study highlights the importance of the timing, magnitude, and variability of low streamflows and the frequency and magnitude of high streamflows as key characteristics critical to assessing how fish communities change in response to streamflow alteration. This study was completed using fish community data collected by the Tennessee Valley Authority, and predictions of streamflow characteristics at more than 600 locations.

The Tennessee River basin is one of the richest areas of aquatic diversity in the country, if not the world. However, expanding urban development, more than 600 privately held small dams on medium to small streams, and withdrawal of more than 700 million gallons of water each day threaten this diversity. Understanding the effect of streamflow alteration on aquatic ecology is increasingly important as change in land use and human population are projected.

One of the examples from the study shows that as maximum October streamflow deviates outside reference conditions by approximately 6 cubic feet per second per square mile, fish diversity may decline by almost nine species in the Blue Ridge ecoregion of eastern Tennessee and western North Carolina. Results such as this were identified across the Blue Ridge, Ridge and Valley, and Interior Plateau ecoregions for 11 categories of fish and will help resource managers identify when streamflow alteration may result in too much ecological degradation.

"Managing river flows to meet the needs of our growing communities and economies will become increasingly challenging in the future", said Sally Palmer, director of science for The Nature Conservancy in Tennessee. "Maintaining our rivers to support an abundance of natural wildlife, including our native fish, is an important goal as well. Studies like these give us better information to ma
