Eagan Neighborhood Lakes TMDL and Management Plans Report

In 2014, the Minnesota Pollution Control Agency listed Carlson (MNDNR ID# 19-0066-00), Fitz (MNDNR ID# 19-0077-00), Holz (MNDNR ID# 19-0064-00), and LeMay (MNDNR ID# 19-0055-00) Lakes as impaired for aquatic recreation under Section 303(d) of the Clean Water Act. In addition to the impaired lakes, the City of Eagan requested that this report include management strategies for lakes that are not currently listed as impaired for aquatic recreation to ensure that lakes with high water resource value are protected. These unimpaired lakes include Bald (MNDNR ID# 19-0061-00), Bur Oaks (MNDNR ID# 19-0259-00), Cliff (MNDNR ID# 19-0068-00), Hay (MNDNR ID# 19-0062-00), LP-30 (MNDNR ID# 19-0053-00), North (MNDNR ID# 19-0136-00), O'Leary (MNDNR ID# 19-0056-00) and Quigley (MNDNR ID# 19-0155-00). The watersheds of these lakes fall primarily within the city's boundaries, however, some watersheds do fall within the boundaries of Inver Grove Heights (LP-30 and Hay Lake) and Apple Valley (Cliff Lake). The land use within the impaired and protection lake watersheds primarily includes residential, industrial and commercial land use. The purpose of this report is to develop total maximum daily load allocations for lakes that were classified as impaired for aquatic recreation due to excessive nutrient loading. In addition to providing allocations for impaired lakes, watershed nutrient reduction strategies have been developed for protection lakes (lakes not currently listed as impaired).
