Iowa Brothers and Sisters, I need some help regarding the Red Rock Reservoir, particularly above the Highway 14 mile long bridge. Last summer, when my brother-in-law and I were boating/scouting above that bridge, we saw a number of barely submerged trees even though the water was 15-20 feet deep. Caution being the better part of valor, we decided to fish below the bridge. Last weekend, I was down to southern Iowa visiting family (I'm originally from Decatur County). On the way home as I was crossing the bridge, I saw several boats above the bridge zipping right along. Here is all I need to know. Is it safe boating above the 14 bridge? How far up can one go before losing a prop? It looks like there's a ton of good fishing up there and I'd love to check it out, I just don't want to have to spend an hour putting along through stumps to get there. Mike.
