Mr. Otto said it will work until the corrugated pipe gives way. Then I will seal it and just use the emergency spillway. It's only ran over the emergency spillway once in 2 years and that was for about 6 hours. So hopefully that will be several years down the road.
2 acre pond only 1/3 of an acre over 4 feet deep when full so needed a way to retain more water. This will add about 3 feet of depth bringing the pond to 2.2 acres.
Trying to be optimistic and anticipating the forecasted 5 inches of rain over the next 10 days will fill the pond back to full pool.
Do you have enough freeboard in your dam to support this?
