I have noticed that as of late, the lake level has become very cyclical. It is peaking around 6am to 10am and bottoming out in the late evening everyday. Anybody know valid reasoning behind the generation cycle. Not looking for a "Cliff from Cheers" kind of answer (the older guys will understand). What's the logic?

Go to the lake level site and check it out. Look at that sawtooth for the last month.

typical summer pump cycle..... drain during the day to generate and the pump-back from Leesville at night (off peak when demand if not as high - using electricity from other AEP assets that have a more constant generation profile - thus spare electricity ) to have water back up in SML to do it all again the next day...... In Fall/Spring and much of winter there is not as much of a demand for generation so its more of a weekly cycle

If you've not had a chance to go to the AEP visitors center at the dam (accessed via the Leesville side), you should - its an interesting time - self guided tour through the visitor center - not sure if they have scheduled organized tours of the dam / generation mechanisms or not, but still an interesting way to spend a few hours one day

ahhh, Bach. This explains some of what I experienced on Leesville this weekend.

If you anchor in a backwater or cove for a while, you can watch the water rise and fall, and you can see the current changing directions several times over the course of a few hours.

Lately it seems that the lake is regularly kept below normal level. Fluctuating between 1 1/2 and 2 feet below normal. Why is that? Is that normal for the end of august?

fairly typical for late summer - you can look back at the historics using the web-site above and see there is often a gradual decline over the summer - likely driven by lower rain-falls and increased down-stream demands.

Looking at the lake level chart for 1 year it seems that the "Normal Level should be 793 not 794.

What they mean by normal lake level is the height after leesville has been pumped back. The 794 is their goal and after pump back during normal flows, yes it's 794 typically.
Mean lake level over the course of a year is something else completely and mostly out of their control.
It was only a few years ago that they introduced new regulations to keep lake levels closer to nominally full. Prior to that, 3-5' low in the fall and winter was pretty common.

Thanks Johnr, This morning it's down more. When does the State Park ramp become a problem to launch and retrieve? I was there that year it was down 4-5' and had to ho over to Parkway to get the boat out. Gary

Well, it certinly looks like something is going on. Were down to 792 ft. Can't be a water shortage. Looks like it was 2015 the last time it was this low.

Look back at 2012 The 2015 one was about the exact same time - think they were doing ramp work on some of the public ramps that year - could be something tied to dam work too. Doubt it's due to the new Hardy Bridge work, but I guess it's possible it's in preparation to set some coffer dams or something.
