Biologist Kyle Cutting hand augers a hole in 35" thick ice on Upper Red Rock Lake at Red Rock Lakes National Wildlife Refuge to measure late winter oxygen levels. This effort is to learn more about the Refuge's threatened adfluvial Arctic grayling population and how winter habitat conditions limit the fish's ability to overwinter. Photo by Cortez Rohr/USFWS.
