Lassig, I have a similar situation at my pond. I run my well and I'm at full pool within a day or two, depending on how far down it was when I started. I shut it off for a week and my level dropped two feet. It was similar to the thread titled Ice Bowl. Looked like one of those skateboard parks.

Here in Nebraska, we also have the low winter precipitation problem and because the water I'm adding to the pond is not coming down my banks, but slowly rising from the bottom up, the upper banks are not getting saturated. It makes sense to me why the level drops like it does right now, however I don't like it much either.

I'm taking Scott's suggestion of wait/see.
