April 2018 Lake Levels and Flow Rates

Ah May. When a boater's thoughts turn to...boating! May is now here and with this weekend's Harbor Hop we ring in the "official" start to the 2018 boating season on the Lake of the Ozarks. There's only on tiny problem. We don't have a normal pool level yet (658.5-660)!  Take a look at April's chart leading up to today. May 7th Update - Ameren has raised lake levels over one and a half feet in the past week! Lake levels are currently holding at about 657.3'. Another foot would be nice.

Lake level's are rarely at full pool by May 1st but two feet below the five year average is a bit unusual. To be fair, there hasn't been a lot of rain and Ameren has not been generating much power, none at all in fact for the last week of the month. So why are lake levels staying low?

This is an interesting condition actually. With flow through the dam steady at about 3500 cfs, and a total average inflow of 10,000 cfs from various sources to the lake itself, we should be seeing a steady, if not small rise in lake levels. One would surmise that the usual water sources such as the Niangua River, Osage River and various springs must be in a low flow condition.
