Not bad at all. We just spent 4 days out there and the mosquitoes and black flies were very tolerable. I don't think I put on bug spray twice in that time Got home last nite to our house 15 miles away and were immediately attacked by hordes of them... I think the water level around the TFF is pretty constant so you don't see the variation year to year.

There is a small mayfly hatch going on that the fish are rising for. Wish I had had the fly rod.
