I do a lot of work at Red Rock Lake in Iowa
csteffen: You hang out anywhere else in IA? I'm in SE corner and (used to) fish Coralville a lot. Don't remember ever seeing this type incident up there, but it makes sense...just curious as there aren't all that many Iowegians on here.
Born and raised in Northwest IA, in Cherokee to be exact. Been all over the state. I worked two summers collecting lake water for a professor at Iowa State. We would sample from about 6 am until 3 or 4 pm and then use the boat to fish. We sampled 130 of the biggest lakes around the state. As of two weeks ago I have now fished 108 of them.
For the fulltime job I have now I was at Coralville last wednesday shocking fish. That is an incredible lake. So much fish diversity and pretty also. The outlet structure is different at Coralville and they rarely if ever have a gas supersaturation problem. Most of my work is on the Des Moines River (including Saylorville and Red Rock Lakes). Shocking fish on those two lakes is not 1/10 as interesting as Coralville.
We saw a lot of white bass/wipers at coralville in the 10 inch to 5 lb range. Flatheads up to a couple pounds are everywhere. We rarely see large ones though because we are in shallow water. We also shock the river below the lake, it is a quite a site when we pull the shock boat up to the low head dam at the Iowa Power restaurant in downtown Iowa City.
I agree there needs to be more Iowegians on this forum. We are probably the last stronghold of the majestic bullhead.
