Pond Boss Forums POND CONSTRUCTION Building a dam My new house

One rule, which I believe is standard everywhere, is that changes you make to your property cannot affect where water leaves the property. In other words, your pond discharge must exit your property the same place the water drained of before the pond was there.

If you are considering damming a permanent stream, it could be considered a "navigable waterway" by the Army Corps of Engineers, due to proximity to larger rivers. They can be pretty sticky if you want to put a dam on it. There was a thread a week or two ago which discussed the navigable waterway permission problem - you should do a search for it and read it.
