Maybe I am stupid, but I recall that that we have stocked native strain walleye in wood creek. Those fish were in the river before the dam was there on cumberland so I would seem that they would not have any problem with low water which is higher from where they came from. I am sure that they endured higher temps in the summer than the stripers can or they would not be here. Seems simple to me to stock them to keep a walleye fishery with the low water for what we have been told for at least 5 years and the fish that were put here will not do well.
