Just went out myself, and I have to say it was cold as all getup at depth... We dove Mansfield Dam, Jailhouse 1. The surface has a LOT of debris floating around, but once you get close to the dam, its fairly clear. Surface viz was actually fairly amazing (15ish) as we dropped onto the top of the jailhouse, and as we went down the front face viz stayed around 20 until we hit 130, then the muck layer made itself present. By 90' it was at a solid 53 degrees, and there wasn't a true strong thermocline noticeable except for a slight haze at 45'. Today was also the first day I've found the cow, pinguin, and Flamingo, so I consider it a fairly good night!
