This report documents the findings of the Singletary Lake Management Plan. The goal was to identify the management needs for Singletary Lake, analyze alternatives, and then develop a recommended management plan tailored specifically for Singletary Lake.  
The primary objective was to observe the existing condition of the dam and address deficientcies identified during the inspection. 
This report provides a description of the watershed, and the physical characteristics of the lake. monitoring and sampling results. the current nutrient loading to the lake and the trophic state (level of eutrophication) of Singletary Lake.
The purpose of this study is to develop a 20-year, wastewater collection and management plan.  The goal is to develop a plan to help reduce contaminant loadings to Lake Singletary, while complying with Massachusetts Title 5 regulations.
This report documents the existing conditions and the development of management strategies focusing on the maintenance and improvement of the Stockwell Ponds nutrient reducing function and capabilities.
