This was my first encounter with silverjaw minnows and arrow darters. I was pretty excited to see both of them. I was disappointed that I didn't see Etheostoma baileyi; it and E. simoterum s.s. are the only northern snubnoses I haven't seen. The upper Kentucky and upper Cumberland were difficult to sample at the time due to heavy rain, and we ended up cutting the trip short.
Sounds like you were in my backyard. Depending on where you were, I could have given you a sure thing location for E. baileyi, and probably most other darters from central/east KY.
