Plan 3: Moultonborough Bay Inlet Watershed Restoration Plan

 

The development of a watershed restoration plan is currently under way to address water quality impairments in Moultonborough Bay Inlet (MBI), the northernmost feature of Lake Winnipesaukee.

Moultonborough Bay Inlet has historically exhibited excessive levels of in-lake total phosphorus (TP) when compared to the other seven sub-basins which comprise Lake Winnipesaukee.  In addition to Lake Winnipesaukee’s current impairment for cyanobacteria, several waterbodies within the MBI sub-watershed are listed on the State’s 305(b)/303(d) list for failure to fully support aquatic life use due to elevated concentrations of chlorophyll-a, insufficient dissolved oxygen, excessive total phosphorus (TP), and non-native aquatic plants (milfoil).

The Moultonborough community has made water quality protection a high priority, investing considerable resources (both financial and voluntary labor) over the past five years.  To assist the community in focusing their efforts, the Lake Winnipesaukee Association (LWA) has been awarded a NHDES Watershed Assistance grant to begin the development and implementation of a restoration plan that will identify sources of pollutants within the Moultonborough Inlet sub-watershed that have led to the impairments and propose measures to address those sources.
