Welcome to Sunset Lake Association

Do you have questions about weeds or vegetation in or around Sunset Lake? If so, please contact our Weed Watch Coordinator.


Sunset Lake, also known as Wash Pond is about 151 acres in area and is a mile long and a half mile wide. The center of the lake is about 30 to 35 feet. The town of Hampstead maintains a beach on Sunset Lake which is open to all town residents. There is no public boat launch.


Who are we?

The Sunset Lake Association (SLA) was formed in 1982 to help protect our natural resource, promote education and work with local agencies who want to keep the lake beautiful and healthy for all future generations. We are a membership based organization dedicated to serving the best interests of the people owning property on the shores of, or having legal deeded access to, Sunset Lake (a.k.a. Wash Pond) in Hampstead, NH. As an association we bring together the energies, talents, and funds of individuals for common efforts.


What do we do?

The SLA assists in the annual Loon population count, does periodic water testing in conjunction with UNH, boater safety education with the NH Marine Patrol and other fun events such as a decorated Boat Parade and paddle events. SLA is also responsible for maintaining the lake water level through monitoring the dam and weather conditions. 


How can you help?

All of you who enjoy Sunset Lake are encouraged and invited to join the Sunset Lake Association. The annual dues of $25 are small in comparison with the good work of this volunteer organization. We also are offering a new lifetime membership of $200 for anyone who might be interested. Your contributions will go to maintaining this beautiful lake and events like the annual boat parade.

Note regarding RETAINING WALLS from NHDES Wetlands Bureau:

Generally, the repair of a retaining wall structure on a non-tidal water body requires a permit from DES. Depending on the scope and nature of the repairs, one can file a Permit by Notification (PBN) #12 (Repair or replacement of an existing retaining wall.) if one meets all the required criteria outlined in the application packet. If the repair exceeds the criteria outlined in the PBN forms, one should file a Minimum Impact Expedited Application. Should you have additional questions please visit the DES website or contact the Inspector of the day at (603) 271-2147.


Thinking about working on your shoreline and/or retaining wall?


If so, please read more to familiarize yourself with the Shoreland Protection Act.
