Good call, Jamie. I find that fall trout fishing on the smallest streams in MD is not worth the effort most years. It tends to be on the dry side. Even if it rains, fish stay huddled up in summer refuge pools until the spawn, at which point they should be left alone anyway. Beaver and the Gunpowder are basically the only options this time of year unless you feel like driving to Garrett County.
I don't believe this drought is long enough in duration to have any lasting impact. We're getting good rain today and more is on the way early next week.
I haven't fished a whole lot lately, but I experienced mixed results from the dry conditions. On some ponds, it meant the water I could reach by casting with fly gear was too shallow and weedy to produce much. On another pond though, it meant the bank was dried out and firm enough to walk on, which is not possible other times of year. As a result I was able to access new parts of the pond and had great bass fishing.
