Billy Carter is a longtime guide on the lake. He and his wife Dottie grew up in the area. They have some cabins in Uncertain for rent. Several of them have access to docks when you are not on the lake. The link will be below, that is where I stay. They also own Johnson Ranch Marina. Billy and his guides are a wealth of knowledge which they will share. Chaz one of the guides also grew up on the lake and is a great young man.
I usually fish for crappie/yellow bass, bream and catfish...but if I were fishing for bass in the summer I would start with Texas rigged worms in watermelon or grass. Frogs worked slow around the grass and pads. I am sure one of the guys can help you more.
Getting lost - can't speak to that, I have fished Caddo since I could hold a rod growing up in Cass County. If you let get dark it can be daunting. Mark your launch point on your GPS. Stay close to the boat lanes as it gets dark at least until your comfortable with the lake.
Gators - they are there, but no biggie.
Maps are available at Johnson Ranch.
Depending on where you fish the water can be shallow and instant death on a prop. There are a lot of places a go-devil type is needed.
If you want to see some big gators get Chez to take you way up in the backwater in a Go Devil.
