Phosphorus Control Action Plan and Total Maximum Daily (Annual Phosphorus) Load Report: Threecornered Pond, Kennebec County, Maine. Threecornered Pond PCAP-TMDL Report, Maine DEPLW 2002-0562.

摘要

The objectives of this project were twofold: First, a comprehensive land use inventory was undertaken to assist Maine DEP in developing a Phosphorus Control Action Plan (PCAP) and a Total Maximum Daily Load (TMDL) report for the Threecornered Pond watershed. Simply stated, a TMDL is the total amount of phosphorus that a lake can receive without harming water quality. The Maine DEP, with the assistance of the MACD project team, will address and incorporate public comments before final submission to the US-EPA New England regional offices. Secondly, watershed survey work, including a shoreline, septic and town roads survey evaluation, was conducted by the MACD project team to help assess direct drainage nonpoint source (NPS) pollution sites and total phosphorus reduction techniques that would be beneficial for the Threecornered Pond watershed. The MACD Project Team did not attempt to conduct a full-scale watershed survey for Threecornered Pond since the China Region Lakes Alliance (CRLA) intends to conduct an extended watershed survey later in 2003. Instead, a limited survey focused on the state and town roadways and numerous camp/private roads as well as the shoreline of Threecornered Pond. The results of this limited survey are intended to be a source of additional information on NPS pollution sites for the CRLA, the Threecornered Pond Improvement Association (TPIA), and the watershed municipalities of Augusta, Vassalboro and Windsor. It is anticipated that the mitigation of these sites can be addressed using available programs and resources through the CRLA, the TPIA, the Kennebec County Soil and Water Conservation District and Maine DEP.
