Detention Pond In Floodplain
Detention Pond In Floodplain
(OP)
Hello all-
New to the forum. While I am an engineer by training and in trade, my question is not in my area of expertise. We recently purchased some acreage adjacent to our home. Most of it is in the floodplain with a semi-dry creek running through it. When we have regular rain, as we have this year, the creek flows more or less continually. It's usually a couple of feet wide and a few inches deep. We've been fairly dry for the last several weeks and it's still flowing.
The pasture on the north side of the creek is dry. Across the creek to the south is the lowest spot on the property and it is still quite wet. I'm wondering if I can dig out a 3-5 acre pond in the lowest area. The water table in this area is very high. When we have heavy rains, water will stand back there for days and weeks on end. I know for sure that the pond would overrun in the heaviest rains.
If someone could point me to some resources or existing threads, I would greatly appreciate it.
Thanks-
Chris

Thanks for the info. So I went to the Wetlands Inventory Map and found some info. I overlaid the WIM data along with our county 100 year floodplain map over an aerial photograph of the property. I also have a contour map if that would be helpful. My main question is, is this 5 acre pond project doable strictly from a feasibility standpoint? The area between the two creeks is very wet most of the time. The area south of the smaller creek is also very wet. My guess is that the water table is pretty high and that I would be excavating in water and mud. I think I can keep the excavator on dry ground and reach where I would need to. I'm just curious if it's even a thing that can be done. Appreciate your help!

When your title said detention pond, I thought you meant a pond to reduce runoff from new impervious area. Those are not allowed in flood plains.
Maybe you can spin it as creating habitat for waterfowl or something like that.
