Three of the lakes in the FWA are excellent to paddle and explore. I'm generally out there 2-3 times per week and still find new scenery. My favorite time to go is at night when the critters are out. The 3 larger pits are about 1.5 miles long with fingers and coves to divert to.

I guess that I should mention that the Bluegill and Crappie fishing is very good, but I'm out there to paddle.
