LAKE OF THE OZARKS, Mo. (Lakeexpo.com) – Bagnell Dam operators have played it right this spring. When the Corp of Engineers called AmerenUE to request a minimal release of water into the Osage Basin from Lake of the Ozarks to take pressure off the flooding Missouri and Mississippi rivers, the lake was ready.
Already drawn down twice this spring to a level of 654, the water level could accommodate the Corp’s request while still having a couple feet left over to take on water currently held back by Truman Lake to be discharged in the coming weeks raising Lake of the Ozarks to full pool by Memorial Day Weekend. In a perfect world, the lake would rise at a rate of a tenth of a foot per day.
Bagnell Dam has not had to open flood gates in 2011 and Hogg sees little likelihood of it happening this spring – unless the watershed gets hit by a major rain event.
Currently, the Osage Basin and Missouri River are not in flood stage and it takes several weeks for discharge from Lake of the Ozarks to reach the Mississippi River.
“We’ve actually been very fortunate. We have had normal rainfall for spring, much of it has fallen south of us,” said Jerry Hogg, superintendant of operations of the Osage Plant at Bagnell Dam.
Bagnell Dam is scheduled to run turbines at heavy generation today, and medium generation Saturday and Sunday generating lake levels of 557.75, 657.85, 657.95 during the next three days, respectively.
