Ahhh I see...couldn't see pictures before. Looks like you are right up to a creek...doubt you'll find a ton of glacial till there...probably a Colo or a Kennebeck soil type. 10 ft contour layers...so you're on a terrace of the creek-bed/valley. 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.
Good luck to you! Look forward to seeing the progress...

Hope it goes well for you and that your pond turns into a good little fishery.


An after thought, in Sarpy Co. that is most typically a Judson-Nodaway complex (not a Kennebeck or Colo)...Silty Clay loam with a high water holding capacity (both soil types). Depth to a restrictive layer or (clay) is greater than 60". Percolation rate around a 1/4" to 1/2" an hour. Depth to ground water probably in the 70-80" range. 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!
