How to Get a Dam Permit

If you want to create a pond on your property by damming a creek or river that runs through it, you might need to obtain a dam permit. Small dams that create only a minor barrier to water flow are generally not subject to regulation. If you're building the dam on your property, anything that has a distinct impact downstream needs a permit.

Instructions

1. Obtain a copy of the United States Geological Survey (USGS) quadrangle map for your project site, if your dam will likely affect a large area. You can find maps for sale on the USGS website.

2. Check for wetlands or other sensitive areas in your planned project site. You can research sensitive areas through your state environmental agency. You can find a list of all state environmental agencies at the U.S. Environmental Protection Agency website.

3. Draw accurate plans of your project, using the quadrangle map if you have it. Be sure to define your project fully in writing so there can be no misunderstanding about

4. Contact your state environmental agency to find out state policies about dams. All states have different policies depending on their particular waterways and water access.

5. Share your plans with the state agency so they can review whether you need a permit. An inspector may also need to visit the proposed dam site.

6. Contact your district office of the Army Corps of Engineers if the state determines that you need a federal permit, which is likely if your project affects navigable waterways. Submit the required information to them.

7. Get any decisions and comments in writing in case there is any problem with your permit. Keeping good records can help you avoid problems in the future.
