Never found a water hydrant
Nice Park, for free in the off-season.
4 RV sites on Lake Henryetta, a few miles east of town on New Lake Rd. 30 amp electric and potable water. Shade trees and a small beach. Friday night and no one else is here. Very quiet. Nice!
Used the area marked Campsites near the SW entrance. No electric at these sites. It looks like the park is being renovated as there are piles of gravel around and some heavy equipment/construction trailers. This is a large lake and will be beautiful when the work is done. It was fine for a one night stay - no noise, very peaceful.
