This draw down will severely y unpact <br /> recreational use of the pond as well as on the biota. Boat ramp use was severely limited this <br /> past year due to low water levels. Any further draw down of the pond would render the ramp <br /> next to useless and severely limit public access to the pond. The Fishermen's Cove area is a <br /> shallow bay heavily used by shore anglers. Reduced water depths in this section would cause <br /> severe negative impacts to anglers and other recreational users of the pond. <br /> d. Johns Pond. Reduced groundwater flow to thisond would have impacts, similar to <br /> P P � . <br /> those on Ashumet Pond,to the trout population and fishery. A person fishing caught the state <br /> record rainbow trout(13 lbs-5 oz)on Johns Pond in 1993. Large reductions in groundwater <br /> flow to Johns Pond could severely impact the holdover trout fishery. Reduced water levels in <br /> Johns Pond could also impair the alewife run which travels up the Quashnet River(and <br /> sometimes the Childs River)to spawn in Johns Pond. <br /> e. Coonamesset Pond.and Coonamesset River. Coonamesset Pond currently experiences <br /> low water level problems in relation to the herring runs up the Coonamesset River. They must <br /> mitigate potential draw downs or reductions in groundwater supply from the plume <br /> containment project to this pond. Long term reductions in water levels to this system could <br /> harm the herring run while groundwater reductions could impact the stocked sea run brown <br /> trout fishery of the river. <br /> f. Groundwater Supplied Streams. Changes in groundwater levels and flow patterns <br /> may impact some groundwater fed streams on the Upper Cape. These cold clean streams <br /> support wild brook trout populations. Wild brook trout populations are a scarce commodity in <br /> eastern Massachusetts due to 375 years of man made changes to water flow. <br /> Coldwater streams that groundwater mounding could impact include the Pocasset <br /> Rivera the Quashnet River and the Mashpee River. Increased discharge of treated groundwater <br /> to the river may negatively impact the fishery if it increases the temperature of the <br /> groundwater or if it decreases the dissolved oxygen concentration of the groundwater from <br /> ambient conditions at the discharge site. System designers should ensure the system raises the <br /> dissolved oxygen levels of any treated groundwater discharged to a groundwater fed stream to <br /> saturation conditions. <br /> The Mashpee River is a major natural resource,supporting a herring run.,the best wild <br /> brook trout population in southeastern Massachusetts and a state listed.threatened fish,the <br /> American brook lamprey. The Quashnet River supports a wild brook and brown trout fishery <br /> due to groundwater flow. The river's trout population supports a catch and release fishery <br /> between Route 151 and Route 28. This area contains the primary spawning areas for the trout <br /> r <br /> population of the river. Brook trout in particular requires cold, clean upwelling groundwater <br /> to select their spawning sites. <br /> g. Rare Species Habitats. Changes in the Upper Cape Aquifer could impact the <br /> abundant habitats for rare wetlands species in the area surrounding the Massachusetts Military <br /> Reservation. They should consult the Natural Heritage Program of the Massachusetts Division <br /> 6 <br />
