Sunshine,
The water/electric sites are fairly shady. Most have plenty of shade to be comfortable and some have a covered table ( maybe 50% ). They are spaced fine, some low trees and bushes between each site ( some better than others). We have stayed in 13 and 10, both by the restroom. I have found that if you tell the person selecting your site what is important to you, they will fit you into the best vacant site available, they know their park best. Only once did I decide to change a site ( at Bastrop, in the "Y" of the camping loop, right out in the open).
As for fishing, the river is not super close to the campground. We chose to drive when going swiming or fishing. There are 4 main sections of river to use which have easy access. The first is just above the water crossing upon entering the park. Bass and cats would be there, also good swimming. Location #2, just past the water crossing. During February/March, this spot gets stocked with Rainbow trout. There is a deep pool with lots of current. The water is shallow in places here but the current 5 feet out is quite strong for little ones. The picnic tables in this location are far from the water, not good for supervising swimmers. This is also a great place to "put in" for tubes and canoes. (Tubes are $5 a day) the 3rd spot is further downstream. The picnic tables are high up on the bank ( which are caving in from the water ), in a pecan grove , lots of shade ( just not much beach front but plenty of shallow/protected water for kids. The last spot is the "Tube exit" point. There is "beach" accessable past here but its all river rock. The water here is mostly waist deep, a lone bench was on the bank under a shade tree. This spot is the furthest from a parking lot but closest to the campground. Check the map for how far. The first 3 locations had parking lots, #3 the biggest lot and most shaded picnic tables.
In addition to the catfish, bass and trout in the river, there is a small lake Buck lake about a 1/3 mile from the campground. We saw many anglers try for the bass, cats, and bluegills in there but never saw one caught. This lake is very pretty, like out of a romantic movie. We had hiked around it and startled a huge herd of deer. There are loads of turtles and we never saw a single snake.
