We were camped in Warm Creek last weekend (mid Oct) and at least 6 people in 4 different families came home reporting swimmers itch. The itch ranged from mild general itchiness all over the body, to a mild itchy rash with red dots. We've never had swimmers itch in all the years we've gone to Powell so I thought I'd post about it to see if others have come across it. We weren't swimming in scummy water. Water temps were 73-75 degrees.
