Center Harbor Bay Sub-watershed Management Plan

Our recent and ongoing activities have focused on promoting and developing a watershed wide management plan for the Lake Winnipesaukee watershed through a partnership and subwatershed approach. We have been working closely with the Lakes Region Planning Commission and other conservation and environmental organizations on this effort, and can proudly refer folks to the award winning on-line tool “Winnipesaukee Gateway”, developed to inform and involve the public, provide opportunities for individual action, and enhance coordination of activities and communication between and among communities throughout the watershed.

Work has begun in Center Harbor Bay to develop a subwatershed management plan. The Center Harbor Bay Subwatershed Advisory Committee has been formed and will be working on identifying issues of concern and sources of pollution. Lakes Region Planning Commission is working with the Lake Winnipesaukee Watershed Association to facilitate this process. Check back for updates as well as on the Winnipesaukee Gateway website. If you would like to be put on an email list, please contact Dari Sassan, LRPC, at 279-8171 or Pat Tarpey, LWWA at 581-6632.
