it actually gets pretty cold there in the winter months. its down into the low 30s at times.
not to mention this is the colorado river....which is technically melted snow. 
if you guys wanna feel cold. go to willow beach, just south of the hoover dam. its ass cold year round because it comes out from the bottom of lake mead.
Yeah, that water temperature sucks, I think there's a Trout hatchery in W.B.
Water temp coming out of Davis Dam is perty nipple-ey all the time also, but Willow Beach is insane cold.
