Try out Bailey Lake in Burleson. There are some in the main lake but I've had the best luck in the smaller adjoining tanks and Hidden Creek running through the golf course.
More people are fishing it now and it's starting to get trashy in places though, so I try to pack out more than I bring in.
Have fun and good luck.
There is also a new community pond at the new park on main street in Joshua. It was supposedly stocked and has fishing rules posted but I haven't fished it yet.
