Traditional lake now.........go to Squaw.
It's actually nothing like a traditional lake....in fact it may be the only lake like it in the State of Texas. I say this because the plant runs full time (mostly) during the warmer months of the year resulting in water temps that average 100-104 on the North end for most of the Summer. Even way up in Blundell, the water temp in those pads was 95-99. Then once the peak energy demand cycle is over and the plant goes off-line the water temps plummet and become "normal" over the late Fall and Winter months before going back in line in late Spring to early Summer.
I've had conversations with the TPWD Biologist that oversees Monti (Tim Bister) and when I asked him what the short and long term affects of the new plant set up would be on the bass, his answer was he really had no idea because there is no other similar scenario to compare it to. I was personally hoping with the water being cooler more of the year, that the fish's metabolism may slow down enough to allow more of them to get to double digit status. Right now, DD bass are more of a unicorn on that lake.
Anyways, enough blab. To address the OP, if you are coming expecting the Monti of several years ago where you are throwing top waters the week of Thanksgiving, then take the other's advice and head to Squaw. Monti could still be great this weekend and I personally plan to check for myself, but with the hard freezes the last 2 mornings, my expectations are very low.
