   Eagleville Lake is a 79.6 acre reservoir located on the border of Coventry and Columbia, CT.  There is a state owned dam and two boat ramps located on the south end of the lake.  Both ramps are car top/carry in only.  There is an 8 mph speed limit on the lake.  The lake is shallow with the deepest portion in the south near the dam at 2.5 meters.  Much of the lake is less than 1 meter deep.

   This CAES IAPP survey found 15 native species and one invasive species of aquatic plants. The invasive was Cabomba caroliniana (Fanwort) and it was the most dominant plant in the lake.  It grew in very large, dense patches that sometimes extended across the lake, reaching both shores. Eight transects consisting of 10 points each (80 points total) were taken around the lake.  C. caroliniana was present on 81% of the points where it usually reached the surface.

   Three native emergent species with floating leaf were common; Brasenia schreberi, Nuphar variegata, and Nymphaea odorataB. schreberi and N. variegata were the dominant native plants in the lake.  The survey team could not navigate to the ends of the larger coves and the northern tip due to the abundance of these two species.  Surveying had to be done at the edge of the passable area. 

   The most species rich area of the lake was in the north.  Nine species of plants were found including: B. schreberi, C. caroliniana, Elodea nuttallii, Pontederia cordata, Potamogeton natans, Utricularia gibba, and Utricularia macrorhiza.  The northern end was the only portion of the lake where U. macrorhiza was found.  Other plants found with less frequency were: Ceratophyllum demersum, Ceratophyllum echinatum, Eleocharis species, Ludwigia species, Potamogeton pusillus, and Sagittaria species.
