LAKE OF THE OZARKS, Mo. — Water flow through Bagnell Dam has dropped by nearly two-thirds, as Ameren has closed the dam's floodgates and the Lake of the Ozarks level reaches an elevation of 660 feet, which is considered full pool.
As of 1 p.m. on Dec. 31, the Lake level was 660.01, measured at the dam, with 38,932 cubic feet per second (cfs) flowing through the dam’s turbines.
Truman Lake, which feeds into Lake of the Ozarks, is a different story. The Army Corps of Engineers have shut off Truman Dam completely, and that lake is more than 16 feet above its normal level.
Bagnell Dam Director of Hydro Operations Warren Witt pointed out Truman Lake was built specifically for flood control, and is more capable of handling large fluctuations in water level, since there is significantly less shoreline development than at Lake of the Ozarks.

An Ameren spokesperson said the Bagnell Dam floodgates were closed because inflows had dropped as the rain ceased and Truman Dam was shut off; turbines were able to handle the remaining necessary drop in Lake level. No timetable has yet been communicated regarding when Truman Dam will begin releasing water again.
