It could be a time of year thing .Populations of
various fishes can change with time of year in my
local creeks . Even area to area of the same creek
.Dams would not be a good thing and house construction
in the area isn't a hopeful sign .Either one changes
habitat conditions . DR. Robison in his book Fishes of
Arkansas mentions something to the effect that
abundant watercress plants often equates with abundant
SRBDs .Ive found this to be true in my area too.
Evidently they like the same water conditions .
