Welcome to the Experimental Stream Lab at the US Geological Survey's Leetown Science Center in Kearneysville West Virginia. At this lab we're interested in stream ecology and how fish respond to land use and climate change. This experimental stream lets us test these questions in new ways. We have four stream channels comprising a series of pool and riffle chambers. We're learning how brook trout respond to increasing stream temperatures and invasive species, as well as the interaction of these factors. This work helps us better understand how to protect and restore native brook trout habitat in Appalachia. There are many other possible applications of this stream lab for ecological research, and we invite your ideas and look forward to the collaboration.
