What L. Huron lacks in Salmon it makes up for in Steelhead. Just need to wait later in the Fall then the Salmon for them to come in. I have a long time friend who runs a charter on Huron out of Harbor Beach. They've been stacking 'Steel' like cord wood this year. If that's any indication, it oughta be a good year for Steel on the Huron tributaries asuming we get the right weather to trigger a concentrated run. He also tells me the bait fish (smelt) populations on Huron are recovering and the Salmon fishery is slowly recovering as a result. It's just the food chain finding it's own balance, I guess. Hopefully Huron Salmon will be back to consistantly fishable levels in just few years.
As far as Salmon on L. Michigan tributaries go, they are right on time. The early fish usually show up in the lower portions of the rivers at the end of August. By mid-to-late September, the action will be hottest with fish all through-out length of the rivers. Salmon are usually done by October, but hold tight because hungry Fall Steelhead will be right behind them.
