Swimming in Sand Hollow

Did a 6am swim with the St. George Tri Club (Rob, James and Jamie) in Sand Hollow Reservoir. The reservoir will be the site of the St. George Ironman swim. Apparently the reservoir currently has "swimmer's itch", a parasite that can causing rashing. Supposedly it was isolated to a shallow part of the lake, while we were swimming in the deeper area near the boat ramp. It was a nice mile-mile and a half swim...I dried off fast and I'm hoping that did the trick to avoid rashing.
