Phosphorus Control Action Plan and Total Maximum Daily (Annual Phosphorus) Load Report: Upper Narrows Pond, Kennebec County, Maine. Upper Narrows Pond PCAP-TMDL Report, Maine DEPLW 2004-0680.

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 Upper Narrows Pond 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, will address and incorporate public comments before final submission to the US EPA. Secondly, watershed survey work, including a shoreline survey, was conducted by the Cobbossee Watershed District to help assess total phosphorus reduction techniques that would be beneficial for the Upper Narrows Pond watershed. Watershed survey work included assessing direct drainage nonpoint source (NPS) pollution sites. This project involved identifying NPS pollution sites though field surveys, and BMPs were recommended to help mitigate potential phosphorus and sediment loading to Upper Narrows Pond.
