Lakes Management and Protection

Ensuring the vitality of lakes and ponds as biological, social and economic assets of the state.

The Lakes Management and Protection Program (LMPP) was created as a result of the recognition of competing uses of the state surface waters. The program, defined in RSA 483-A, promotes communication and coordinated action among the many stakeholders who use New Hampshire's lakes. Program staff provide technical assistance to the public on lake management issues.

Lakes Management Advisory Committee

The Lakes Management Advisory Committee (LMAC) advises NHDES on state-wide issues affecting lakes and ponds. The LMAC has 19 members representing lake-front municipalities, planning boards, conservation commissions, realtors, NH Lakes, the State Conservation Committee, the scientific community, tourism, business and industry, fishing, marine dealers, the Fish and Game Commission, conservation, and state agencies. The LMAC provides a forum for exchanging technical assistance and ideas among state and federal agencies, municipalities, private businesses, conservation interests, and the public regarding lake management issues. The LMAC provides input on state legislation related to lakes and ponds, making recommendations both to the NHDES Commissioner and to state legislators in support of healthy lakes and public access.
