I've fished a couple of the locations mentioned above. No luck, tried swimbaits, crankbaits and jigs. I'm still new to fishing the Columbus area and still have plenty to learn. Took all week off from work, hopefully things start looking up later this week.
If I had to pick my top picks for saugeye this time of year in the central Ohio area, I'd go with Indian Lake, Deer Creek, or Alum Creek(in that order). I have never had much luck in Alum Creek or Hoover for saugeye but I've seen and caught several out of Alum. I haven't caught a saugeye out of Hoover in the 3 years I've fished it. I Probably don't know the secret places for eyes or can't reach them in the mentioned reservoirs seeing how I fish from the bank for saugeye. Indian has been the exception to that with it's shallow depths and plenty of rip rap lined shoreline.
