Looks like your watershed is pretty big. Is this a Dam with a tube, or a dug-out? Just looks like you might be plugging the little "cut" into the creek. Id bet there's some springs by the looks of it. That soil type is probably a silty clay, moderately well-drained, water holding capacity for a Kennebeck or Colo soil isn't that great when compared to clay, but you might hit some better stuff the deeper you go.

I think I need an interpreter.
Haha. I think the watershed is plenty big, especially considering the nice hill to the east and the smallish size of the pond. It's a dug out and I don't think I know what you mean by "plugging the cut of the creek".
I certainly hope to hit some good clay. There is very good clay around the creek banks and bottoms, but as you can see from the diagram, the elevation is pretty different. But this shouldn't be a problem either way as we have a source of good (free
) clay just up the road. And it's stuff that's proven successful in hold pond water.

Looks like a lot of farmground around it...thought of planting a filter strip around it? I like these kind of projects if you can't tell!

There will be an adequate filter strip between the cropland and the pond. Planning on starting with a rye, then letting natural foliage to take over, as long as it's thick and low. And it's my dad's property and I'm going to try to convince him to make the surrounding fields into alfalfa instead of the rotating bean and corn.
