Jakes Pond

Jakes Pond is located to the south of Fathom Road, east of Mooring Circle and north of Wall Pond. It appears to be a “true” kettlehole pond with no surface water inflows or outflows; its water level will be determined by groundwater and precipitation. Residential development with fairly large lots (>1 ac) occurs on the eastern and western shorelines, while the southern shoreline is undeveloped and the northern shoreline has a town beach area. Public access is informal via the beach area. There are no records of MassDFW management or fish stocking. Water quality samples were collected during the 2014 PPALS Snapshot appear to be the first water quality samples ever collected from the pond. WATER QUALITY Jakes Pond is relatively shallow with some loss of clarity at the time of the 2014 PPALS Snapshot. Temperatures and dissolved oxygen readings show a well-mixed water column with DO readings generally close to atmospheric equilibrium (i.e., ~100% saturation). Comparison of shallow and deep chlorophyll-a and total phosphorus readings show similar readings, reinforcing likely regular mixing of the water column. Available readings do not indicate that there was significant sediment nutrient regeneration or sediment oxygen demand at the time of the Snapshot. Based on the single set of 2014 PPALS Snapshot readings, Jakes Pond is not impaired. This assessment is generally based on TP and chlorophyll-a concentrations below their ecoregion thresholds, similar surface and bottom TP concentrations indicating insignificant sediment regeneration and DO concentrations throughout the water column close to 100%. Additional monitoring would be required to confirm this assessment. Available monitoring is insufficient to resolve the need for or extent of management options.
