Thanks for the info. Sounds like they can be spawning just about anywhere and in the springtime. The reason I asked was someone just posted in the NE forum about catching a bunch in the spillway(at least I think that's where they were!) below Berlin. From ice fishing there this winter, I know there's really good perch in L. Milton and that has to be where they came from but why would they be in such quantities, up river to the dam, and fight the turbulent waters? Walleye and white bass make this trip, but perch...?
