Docks, Sand, and Swim Lines

Here are NH department contacts concerning:


Dock Regulations: NH Marine Patrol  (603) 293-0091

A permit is required.  Docks must conform to size and position requirements.  

In a lake the size of Spofford, NH mandates that a property with fewer than 75' of water frontage may have a dock that is no more than 4' X 24' (seasonal only). Frontage greater than 75' may have a dock no greater than 6' X 30' (seasonal only).

For the most current and complete information, visit NH DES. 


NH Dept of Environmental Services  (603) 271-2147

A permit from DES to add sand to the shoreline is required. It is prohibited to add sand into the Lake. A project involving beach sand replenishment must qualify for PBN approval.
