This will bring in the first major run of steelhead to all the tributaries entering the Great Lakes. Every ditch, ephemeral channel, road side drainage swale, you name it will have steelhead/browns/salmon in it come tomorrow. If I had nothing to do this weekend I def. know where I'd be.
The steelhead in Erie area haven't been able to make it up hardly any of their rivers because of the drought. All those fish that usually run in September and early October have been waiting for this moment. The rain should stop sometime tomorrow and the creeks will be fishable ~12 to 24 hours after the rain stops. The fishing is silly good just when the water starts to drop and the visibility is only 12" or so. I don't think the pressure will be too bad because people have been waiting for this moment from MI to NY and will be spread out all over the place. Once the water lowers and clears, the crowds will be horrible in the popular larger rivers when everyone can see just how many fish are there but it's that magic time when the river just starts to clear and when most people think it's unfishable is when you want to be there. Pretty much from here on out until the ice sets in will be decent but nothing like what tomorrow might be.
Only the larger, dam controlled rivers have seen many fish so far this season. All the other places will explode with fish with this rain. Too bad I went to Mexico last week.
