Late last summer, in the worst of our drought, Raccoon Creek was reduced to
a series of near-stagnant pools and a few (possibly spring-fed) riffles.
The water seemed as warm as bath water & I didn't expect to find much in
the way of fish. The blackbanded darter was the ONLY darter I did find
under these conditions. I have also noticed that F. stellifer seem to
survive in areas where little else can.
