There is a little of what I think is considered terracing so that helps but I think more can be done. I definitely see the soil wash out on really heavy rain events.

My property is a 3/4 acre wedge, like a triangle if you lifted two corners such that the slope was around 1ft over 10ft average then tipped one of those corners up a little higher than the other.

I'm afraid to dive into a pond just yet and it would have to be very small.

I'm actively working on building up the lowest point to at least slow the water down and hold onto more of the water. My plan is a little hugelkultur bed with a bunch of deadfall and 2 cu yd topsoil.
