I have found some info on quillback location nearby but only a picture of them and the creeks name. There is one low head dam on said creek. Should I be searching below this dam or above it (headwaters?) for these fish? I have found zero information on whether these fish make a migratory run for spawning or if they typically inhabit small ranges all year. As far as technique and habitat I've done a good bit of reading but any tips are appreciated. The body of water is sugar creek, IN.
