I've found large schools of whites in 6" of water in 1' wide feeder creeks at times, my guess is they're either stunted or more than likely the adults find their way to deeper water in wider creeks.I think in the beginning it was stressed. I took that pic right after acclimating it. I can't believe that fish can attatin that size. Its from a very small creek where the deepest pool was at most 2 feet. Its about a mile away from the saw mill river. I have seen these fish before usually one or two at a time vs the hundreds of dace that collect in pools.
There is no such as stunted white suckers in feeder creeks. Adults typically spawns in feeder creeks then migrates back to the lake/river after they're done with spawning. I've found 16-25" ones in tiny creeks during spawning times.I've found large schools of whites in 6" of water in 1' wide feeder creeks at times, my guess is they're either stunted or more than likely the adults find their way to deeper water in wider creeks.
you don't notice the three faded black spots on the body? That's one of the traits of white suckers.Odd coloration for a white, awfully brown. We need more pics from the OP to positively ID it.
