Recommendations
Implement recommendations in the DMF shellfish management plan for Area MB5.3.
Develop a monitoring plan and conduct bacteria sampling to evaluate effectiveness of point (Phase II stormwater permits) and non-point source pollution control activities and other actions and to assess the status of the Primary and Secondary Contact Recreational uses.
Support DMF efforts to improve availability/access (electronic or web site) to water quality and biological monitoring data collected from DMF shellfish sampling stations to assess the status of the Primary and Secondary Contact Recreational uses.
Continue to monitor and review whole effluent toxicity data for the Town of Scituate WWTP (MA0102695).
Work with NSRWA to implement a quality assurance component for their water quality monitoring program.
RECOMMENDATIONS CONTINUED
Support the following actions identified by DMF to study/protect/remediate smelt spawning habitat (Chase in preparation).
Work with the town of Scituate (DPW) to develop water supply management practices that would provide sufficient flows to protect anadromous fish spawning habitat in the Herring River.
Restoration of the riparian buffer zones along both banks of the Herring River adjacent to the smelt spawning habitat should be undertaken. This would include removing an area infested with the non-native Japanese bamboo. Improvements would result in bank stabilization and shading of smelt spawning habitat.
Water quality in the Old Stockbridge Grist Mill channel that drains into the Herring River directly into the smelt spawning habitat area appears to be compromised by unknown discharges and lack of flow. These conditions need to be investigated and corrected if necessary.
South River (Segment MA94-08)
L
ocation: Headwaters from the outlet of unnamed pond north of Congress Street, Duxbury to dam at Main Street (Route 3A), Marshfield.
Segment Length: 4.9 miles
Classification: Class B (It should be noted that the South River is currently listed in the SWQS as a Class SA/SFO/ORW for the entire length (which would make this a 0.007 square mile segment) but the corrected classification in the proposed revisions of the SWQS identifies this as a Class B, Warm Water Fishery, ORW.)
Land-use estimates (top 3, excluding water) for the 11.4 mi2 subwatershed (map inset, gray shaded area):
Forest 55%
Residential 27%
Open Land 8%
South River is listed on the 2002 Integrated List of Waters in Category 3. This segment had insufficient information to make assessments for any of the designated uses (MassDEP 2003a).
