Sebago Lake Protection Office

Located in Standish at the intersection of routes 237 and 35 (address: 1 White Rock Road, if using Google Maps, use “Sebago Lake Protection Office” for accurate location), our Sebago Lake Protection Office houses our year-round water resources, education, and security staff. The office is open 8:00 a.m.-4:30 p.m., Monday through Friday, excluding holidays. Rarely, the office is closed during these hours if all staff are in the field. The Office provides the following resources.

LakeScaping Demonstrations

Our office is surrounded by beautiful demonstration gardens that feature native plants as well as installed practices (called Best Management Practices) designed to keep water and pollution on the land and out of our lakes and rivers; practices installed on our property are listed below.

We encourage homeowners to install these lake-friendly landscaping and development practices and to visit to see what they look like and how they work. Homeowner instructions are available electronically  (search “Environmental Fact Sheets, Brochures, and Posters”) and at the Sebago Lake Protection Office. For more information or to set up a group tour, email us. (Please note: We require a minimum of one month’s notice for tours.)
