Lake levels

Thought he might see this.

Ok, thanks!

Pomme conservation pool is 839.  The actual target elevation is a sliding scale.  Beginning I think around March 15 the target becomes 841 until June 15 then slides back to 839 for a target until fall where it goes back up some.  The spring "rise" is to benefit fish spawn, the fall one is for waterfowl.  I am a little fuzzy on exact dates as I am at home now.  Will see what I can find on line and post it though.  Whatever the target level it is still only a target, mother nature seems to enjoy driving the train, rain/drought etc.  There are several factors that go into determining the rate of release, Pomme and Stockton have a "tandem balance" with Truman based upon things like % of pool utilized at the time, plus benchmark elevations and flows on the Missouri River and all the way to the Gulf.  Compared to lakes like Truman Pomme is fairly stable with a relatively small drainage basin, however when we get a big rain event concentrated in the basin it can rise quickly.

Thank you MOPanfisher, knowed there was a date somewhere for 839 to 841 transitions but wasn’t sure. We have to deal with 60’ rises in the lakes in SE MO. Familiar with Mother Nature spurts, keeps you guessing for sure. 

THANK YOU AGAIN!

The Corps inspects the docks every year, they try to do it April 1st and want the lake at normal pool(839). They then give everyone 30 days to fix any problems, then reinspect 30 days later, again at normal pool. Occasionally they have to put of the inspections a few days/weeks if there is to much perception.

Sadly I can tell you that seldom are the inspections done at "normal".  Would be nice but just doesn't happen often.  Do try to avoid extremely high levels though. Realistically lake level and normal levels seldom have anything to do with each other come dock inspection time.

Agreed, having a dock there for the last twenty years, I can remember sometimes that it was as late as June before the reinspection's have been done. There is some good info on the following site that you can track the last few years.

Just curious, where is your dock at, almost certainly I have been on it at some point.

It's located in zone 22.
