Dave,

It certainly could be, since some of the springs enter the pond below water level. Guess I didn't think of that.

We gained another inch and a half over the last three days, which is pretty close to what we have been averaging since I started monitoring it two weeks ago.

Seems to me that is pretty good considering the area we are currently filling. Guess I could do the math on the volume that we are gaining, but I already have a headache.

I'll continue to update if you continue to keep your fingers crossed.
