Greetings. I am sure someone has discussed this, but I can not locate it.
I am planning a 7 to 8 acre lake. The watershed is about 250 acres. Location is west central part of Indiana.
I am trying to locate the formula for determining the emergency spillway size when the above is given. The watershed is about one third tillable and the rest in woods and pasture land. I would like during the worse rain the water would not be more than 2-3 inches deep on the spillway.
Would someone direct me to the thread or to the formula?
Thank you. Blessings
