We are building the pond so that we stay under the limit of impounding 50 ft acres of water. This avoids the dam safety act permit. This, however, is the Clean Water Act regulations. Permit 404.
Apparently, if you impound more than 300 ft of an intermittent or ephemeral stream, you must mitigate the stream. Mitigate is a payment you make to the government to use the stream. The engineer said that it is $3.50 per foot of stream to mitigate. This pond runs along 3000 ft of the stream, 8 acres total. This is the over $1million dollar permit!
