Here's a little writeup for Del Valle including the hard to find link to the lake level page and a cool link to historic photos of the lake before the dam went in ;)

Cool write up and info, now that I got my boat almost complete I may have to take a trip over there and check it out.

Right on. There should be some frog mats forming up by now in the south end and in the backs of the coves on the main lake. They go for the fat ika at that lake too a little bit in the summer time.

With your little boat I'd try to get over there pretty early in the morning just because in the afternoon there's almost always a breeze coming down the lake from the dam in the summer time. It's hard to hide from the wind there.
