Kayak fisherman has never fished either lake. Any advice on best place to put in, areas to hit? I like crappie, white bass, lmb, striper/hybrid, cats...

The primitive launch at Granger is made for Yaks. Little bit of everything thing in there. The waster level is up in the lake and lots of newly submerged grasses.

Look at
austinbassfishing.com and make a post there for more info.
