Any stocked ponds in the hill country?

I want to introduce my 5 year old to fishing. Like most young kids she has the attention span of a goldfish, and she would probably be complaining if she did not catch anything within the first 10 minutes of fishing. I am looking for a pond stocked with bluegill so I guarantee a positive experience for her first trip. Are there any stocked ponds around the hill country where I could pay a fee and take my kid fishing?
