The Marine Unit was established through a community partnership between the Tyngsborough Police Department and the Lake Mascuppic Association to promote boating safety and protect Tyngsborough’s waterways. Officers assigned to this unit patrol Lake Mascuppic, Long Pond, the Merrimack River, and other local waterways during boating season, enforcing marine-safety laws, conducting boater-safety education, and assisting in search-and-rescue operations.
Training for Marine Unit officers is provided through the Massachusetts Environmental Police, consisting of a 40-hour certification course in marine patrol operations, navigation, and boating-safety enforcement. The unit also collaborates closely with surrounding law enforcement partners as part of the Merrimack River Task Force, ensuring coordinated emergency response and public-safety coverage across regional waterways.
The Marine Unit’s mission is to enhance waterway safety through education, enforcement, and partnership—continuing Tyngsborough’s commitment to protecting life, property, and the natural resources of the community.
