I'm a beach babe at heart and this is the closest I can get in Arizona without planning a longer journey. The lake is very calm. I like to hang out at Butcher Jones Recreation Area because it has a large beach and the water is shallow, good for hanging out with friends or family. We brought our dog last time, which I guess you're not supposed to do, but I kept him on the leash and there were no problems.
FYI- No campfires in the summertime! Bring a grill or sandwiches. :0) Also if you plan on drinking, make sure one person stays sober. There will be cops looking for you on the way out. Going to the lake and getting a DUI would definitely ruin a day at the lake.
