Moultonborough Bay Inlet Watershed Restoration Plan – Request for Qualifications

The Lake Winnipesaukee Watershed Association has been awarded funding from NHDES through a grant from Section 319 of the Clean Water Act, for development of a Watershed Restoration Plan for the Moultonborough Bay Inlet sub-watershed of Lake Winnipesaukee, NH.

Moultonborough Bay Inlet (MBI) comprises the northernmost area of Lake Winnipesaukee, and the sub-watershed extends from Moultonborough through Sandwich, covering an area of 31,556 acres.  The MBI has historically exhibited the highest levels of in-lake total phosphorus (TP) of the eight Lake Winnipesaukee sub-watersheds.

In addition to Lake Winnipesaukee’s current impairment for cyanobacteria, several water bodies within the MBI sub-watershed are listed on the State’s 305 (b)/303(d) list of impaired waters for failure to fully support aquatic life use due to elevated concentrations of chlorophyll-a, insufficient dissolved oxygen, excessive phosphorus and non-native aquatic plants.

The community of Moultonborough has made water quality protection a high priority, investing considerable resources over the past four years.  Development of a watershed restoration plan will assist the community in focusing and prioritizing their efforts by identifying the sources of pollutants that have led to the impairments.
