The objectives of this project were twofold: First, a comprehensive land use inventory was undertaken to assist Maine DEP in developing an Phosphorus Control Action Plan (PCAP) and Total Maximum Daily Load (TMDL) report for the Highland Lake watershed. Simply stated, a TMDL is the total amount of phosphorus that a lake can receive without harming water quality. Maine DEP, with the assistance of the MACD Project Team and the Cumberland County Soil and Water Conservation District, will address and incorporate all public comments before final submission to the US EPA. Secondly, watershed survey work, including a shoreline and septic survey evaluation, were conducted by the Maine DEPMACD project team to help identify the need for phosphorus reduction techniques that would be beneficial for the Highland Lake watershed. Watershed survey work included assessing direct drainage nonpoint source (NPS) pollution sites that were not identified during the Highland Lake Nonpoint Source Pollution Survey conducted in 1997. The Action Plan portion of this report is intended to complement the Watershed Management Plan (1999), recently developed by the Cumberland County Soil and Water Conservation District (CCSWCD) and the Highland Lake Association (HLA). The results of this report includes recommendations for future conservation work in the watershed to help citizens, organizations, and agencies restore and protect Highland Lake. In order to protect the confidentiality of landowners in the watershed, site-specific information is not provided as part of this report.
