not per their site-Buchanan (Buchanan) 5/25: No releases 0 0
Maybe they closed the gates. Buchanan was only coming up an inch or two per day until yesterday. Yesterday morning it was at 989.81. Now it's 990.49, up over 8 inches.
I don't know for sure, I am just guessing based on the water level. Whatever is going on, the silver lining to the floods is that lakes that have been way too low for way too long are coming up significantly.
