Check out the gauge at the dam.

They have been letting water out for over a week… that's those little dips in the graph… about a foot in a little over 24 hours… so it's going to take a while to get it back down to the level they want it.
Haven't heard… is the lake muddy?
Here are some before and after pictures from a rain we had last year…
this should give you an idea of how much the water level can rise overnight with a big rain.
