I haven't been there, but 12ft over pool will get the lake murky to muddy & definitely "trashy" (but I bet there were still people out there fishing !! )
Two weeks ago, according to the COE chart ... surface temp at Dam was ~80deg ... thermocline at 15ft
I suspect the dirty water and 80deg days will keep the lake water warm. It's going to take them about a week and a half to get the level back down to pool, if they keep the current rate of discharge (2100cfs). Fast falling water should push the Crappie out to the secondary drops & just above the thermocline (if it still exists).
As always this time of year ... find the baitballs of small Shad & the Crappie will be close by.
