Levels were reported to Drew McManus in Conservation. Drew emailed that he had removed a 6 inch board from the ladder by the Mill Pond. Conclusions: High precipitation continues to lead to high lake levels. [Agenda topic 2] Storms Drains Lakewood Melissa Ave. Discussion: One of the concerns of the Mashpee Municipal Vulnerability Program was storm water run- off issues. Lakewood Drive is a prime example where undersized storm drains cannot handle the rain and it funnels down the road directly into the lake, also washing the pathway dirt out into the lake. This is one of the prime causes of increased phosphorus in the lake and needs to be fixed with much larger drains. Melissa Avenue is another area with drains that are too small, although in this case, the water runs down Jones Road and floods South Sandwich Rd. Barbara spoke with Catherine Laurent several weeks ago regarding small drains on Melissa and a town truck came up and looked at it. It was unanimously voted to send a letter to the Selectmen about replacing these small drains to correct the storm water run-off. Barbara will write the letter Conclusions: Storm basins in the Lakewood and Melissa Ave area need to be replaced with larger ones to help protect the lake from storm water run- off and further degradation.
