If you have a private property owners approval a valid Texas fishing license and you stay within the game wardens rules and regulations you should be fine.
That is up to the city the park is in. Texas Parks and Wildlife set the minimum lengths for all game fish in order to keep them and the limits of each species per day can be regulated by whoever oversees the body of water. Some ponds are catch and release only. You must have a valid Texas fishing license everywhere except State parks. Better check with Watauga Parks Dept. To get the right facts.
