Last week the temp was around 73-74 as far as I could tell. Felt great. As far as the level, I really can't compare it to much, other than it was about 20 feet lower than the same week last year. Definately down, but plenty of nice water. No floating debris as far as I could tell.
Check this link from our trip. You can see the water level in most the pics.
