My wife live in that area and I have been poking around looking for some fish. Only managed to pick up two tiny white bass so far. We're very new to it all and enjoy the learning.
The water being so high makes the 2499 parking lot a short trip, although it is a bit of a precarious one. I've seen a few kayaks dump up the hill right next to the parking lot (yes, that includes mine).
We had been thinking about going in at the Pilot Knoll park but I didn't think it would be open yet.
Christian says there's catfish in Lake Lewisville but I don't believe it yet.
