The water level at Lake of the Ozarks should slowly start creeping up. Both Truman and Bagnell dams have reduced their discharge levels to approximately 50,000 cubic feet per second. Ameren says they’ll once again begin storing reserves as water makes its way down from Truman. That means the lake level will be going up slightly. The lake level at Truman stood at just over 735 as of early Wednesday morning.
