Shirley Hall mentioned the state park showers for $3.00. I went to the Corp. of Eng. website for Lake Belton. There are 3 parks near us. 1) Rogers Park: This park is closest but has not facilities. 2) Temple City Park: This is a picnic park, (no camping) it has restrooms with showers but doesn't say anything about hot water. 3) Live Oak Ridge Park: This is a campground park and it does say it has showers with hot water. According to the Corp. website day use fee is $3.00. I have attached a map of the lake with park locations. http://www.swf-wc.usace.army.mil/belton/images/Belton_Lake_map9.2_2007.pdf
