Well, here's one coming an entire month after your post as well. Guess this section hasn't gotten off the ground so well yet. I had been in Michigan, where the fishing for both smallmouth and trout was excellent. Since getting back, I've gone looking for smallmouth in some areas local to me (Hopewell) on three occassions. Each time, I've gotten a few very small ones (6-8 inches only) along with many, many sunnies.
I've not fished the Millstone, though I stopped right at Blackwell Mills on the way home from work the other day. I had thought I'd take a few casts below the waterfall, but to my amazement another fly fisherman was already there. I watched for about 10 minutes, and he didn't catch anything. Was it you, by chance???
Another place that I think might be interesting right around there is the pond on the Educational Testing Service (ETS) property, which was recently opened up as public green space. It's a catch & release only pond that, thanks to some big fountains, has not gotten all mucked up. Again, I've only caught sunnies and small, smallmouth there, but I think it has potential.
My next trip is going to be to the Delaware near Lambertville, if you'd like to meet up.
I've been wondering about the small size of the bass. Having not fly-rodded for smallmouth before, nor fished any of these areas, I'm a bit perplexed. I've not caught or seen anything of size. My bet is one of two things: either the places I'm fishing, especially the small streams, got hit very hard by last year's draught, which may have killed off bigger fish. Or, the rain has washed so much bait into the water that the bass just aren't interested in anything else (spiders, hoppers, or even woolly buggers). Any thoughts there?
