Knowles Pond Dam
Northfield, New Hampshire
This project entailed design improvements to the Knowles Pond Dam (NHDES Dam #180.02) for the Knowles Pond Conservation Area. This project involved the removal and replacement of an existing, badly deteriorated, corrugated metal outlet pipe with polyethylene pipe and reconstruction of incidental stone headwalls. The embankment dam was stabilized with the reconstruction of slopes and the installation of a toe drain to address dam stability and seepage concerns.
Additionally, QCC prepared a Dam Operations Plan for the Town of Northfield and provided design and NHDES wetland permitting services. Other tasks included construction cost estimates and assistance in fund raising and grant applications. The project was successful in obtaining grant money for repairs.
