Abstract |
In order to evaluate Toothaker Pond remediation options, current and potential phosphorus sources were estimated under different scenarios. This report contains the following updated information: (1) data on estimated flows and total phosphorus concentrations from the existing trout hatchery; (2) an analysis of the flushing rates of the pond based on pre and post-diversion scenarios; (3) land use phosphorus load estimates; and (4) modeling to determine the effects of various flow and loading scenarios. A preliminary evaluation of pond restoration options is also provided. This TMDL report includes evaluation work done for Toothaker Pond during 2003-2004, including field checking earlier Maine DEP field work, a re-estimation of road lengths and conditions, lake and stream data, and phosphorus loading estimates from land use, hatchery and other nutrient sources in the Toothaker Pond and Meadow Brook watersheds, as well as results of a lake response modeling exercise. |
