Streamflow Alteration Impacts Fish Diversity in Local Rivers
A new USGS study quantifies change in fish diversity in response to streamflow alteration in the Tennessee River basin.
This 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.

Instream Flow Management workshop, held January 24 at the Southern Division, American Fisheries Society Spring meeting in Charleston, SC
This workshop will cover the historical foundations and recent advancements of instream flow science and provide guidance on practical application of instream flow tools and data that support management of warmwater stream habitats in Southern Division states. Early presentations will discuss the importance of instream flows to fish and wildlife and quality of life and will provide an overview of approaches to identify instream flow needs for rivers and streams from standard setting to site-based methods. A review of recent advancements including development of hydrology-based tools, spatially-explicit models, and multi-disciplinary frameworks, will provide guidance on practical applications.
The SARP instream flow resources will be introduced and demonstrated in an afternoon session.
There is still room for more. Go to http://sdafs.org/meeting2014/ for more information about this meeting. Bring your laptop!
