The lakes I had planned on attending are dominated by iowa darter (of the two). However, we can get least by the bucketfull in my thesis sites on the way home. I really don't think it's worth us going out of our way to get least at Riley. In fact, it's probably a better deal to get to Weir, conditions permitting, because there are oodles of tadpole madtom and other more desireable fishes there, including logperch and suckers.
As for calling off... Worst case scenario is that we fish marshes in Ohio and lakes in Michigan. We can also always go to the upper Huron where the river is more of a straight than a river, with all the lakes absorbing the surface volume and avoiding flash conditions. So I say it's a go regardless.
These are the gauges to watch. The pulse already went through the Blanchard, the Maumee is up, but at 6.0 above stage, it's actually EASIEST to work, believe it or not. The fish relate more to the sides, and you can catch some weird stuff this way.
(Look at that hydrograph! Why can't they all be like this!? Pulses are in 1/10ths of feet!)
(the water gets out of there fast, mainly influenced by the crapped up Clear and East Fork. West Fork is where we'd like to go)
