It is understandingly frustrating for residents of the pond to see the ongoing impacts of nutrient loading and the <br /> algae blooms/cyanobacteria that have resulted over the years. My biggest suggestion at this point is to increase public <br /> awareness of the issues because the source of nutrient loading is coming from the pond's watershed, which extends <br /> into parts of sandwich and Barnstable as well. This public awareness includes inspections to find failed/outdated septic <br /> systems, potential road takings where stormwater improvements are needed. Increased enforcement of M,ashpee's <br /> Nitro en Control Bylaw and communicating/working with the towns of sandwich and Barnstable to assess their <br /> contributions to Santuit Pond's watershed. <br /> ""flat should we do moving forward? <br /> Further assessments of the feasibility of dredging and/or alum treatments Corps <br /> C'+MrM' r p f <br /> Engineers) <br /> Bring sandwich, and Barnstable to the table <br /> Assessment of potential road takings within the Santuit Pond watershed (all towns) <br /> Public education/outreach and increased warning signage re. cyanobacteria outbreaks <br /> Restoration of the town Banding at Santuit stormwater runoff improvements) <br /> y e wetland so it can be used as <br /> Restoration of abandoned �. acre cranbeMrr bog north of the fish ladder to native <br /> a nutrient sink. (Conservation Crept./Army Corps funds) <br /> Continue to work with and support the Friends of Santuit Pond stewardship group (information/education) <br /> Summary: Santuit Pond is the shallowest pond) in Mashpee,thus"it has little to no thermocline (turnover),which limits <br /> flushing. The pond has a large watershed which extends to areas 1 miles from the actual shoreline, Contributions of <br /> nutrients(nitrogen and phosphorous)within this watershed are the primary cause of degrading water quality at Santuit <br /> Pond. This issue is compounded by the limited depth of the pond (max of 9 feet in depth with an average depth of 6 <br /> feet) and limited flushing. If we can't control/reduce the nutrient contributions coming from the watershed, the <br /> problem will continue to persist. <br /> 'revs R.
