Can't say how high but it is considered to be high by all the locals. I fish off the shoreline and am going to be spending Memorial Day weekend in the park and am looking forward to some serious fishing. Been out there a dozen times so far and am recently catching tons of small fish; bluegill, crappie, bass, catfish. Had a huge one (walleye?) bite right through my brand new 8# braided Fireline on Sunday. I hear the bass are hitting shallow, near wood right now but I have no first hand experience yet. Jigs/worms have been highly recommended. We will hit our favorite spot this weekend and that will tell what's happening but we had to wait for the park to open. Caught 37 fish there last year in one day 10 am - 1 pm and kept the 17 biggest. Huge crappie, nice assorted bass, can't wait!
