Too cool?!? Our council runs the highest scout camp in the country (10,400 feet), which is also a few hundred miles further north from this one you mention in New Mexico. Camp Steiner offers 24 MBs this year, including Swimming, Lifesaving, Canoeing, Rowing, and Small-Boat Sailing. I believe they also offer the mile swim.
Many of the scout camps in the Utah mountains offer a polar bear event before sunrise, but that doesn't stop them doing other waterfront activities during the days.
I earned lifesaving as a youth in a mountain lake not far from Camp Steiner, and survived the temperatures fine.
I earned my BSA Lifeguard in Bear Lake - several miles further North, but lower altitude.
I think the coldest lake I ever swam was Emerald Lake on Mount Timpanogos. The lake is at about 11,000 feet at the bottom of a glacier, and regularly has icebergs floating in it. That was cold! I wouldn't recommend swiming in that water for any longer than you have too.
