Lori Krider, another graduate assistant in the Water Resources Science program, has found that the water temperature in groundwater-fed streams rises an average of .38 degrees for every 1 degree rise in air temperature. An average air temperature increase of 7.9 degrees by the end of the century, predicted by one Intergovernmental Panel on Climate Change model, could produce a stream temperature increase of about 3 degrees, which would be beyond midges' threshold. That could alter food sources and habitat for trout, the researchers said.
