Bobbss,
We�ve got a bunch here near St Louis. Some with good runoff. Less than half that up at my pond, with no runoff.
Is your pond near a large lake? My pond sits about a mile and a half straight east of Mark Twain Lake. (17,000+ acre corps lake). I�m starting to think that the lake effects my weather. I�ll see big storms barreling in on my pond, but as the clouds go over the lake it seems to split north south, or just peter out.

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
