2009 Aquatic Plant Survey Map of Fall Mountain Lake

Transect Data | Water Data

Fall Mountain Lake is a relatively shallow 30-acre private lake located in Terryville, CT. Its shoreline is highly developed with residences. There are two community beaches and a small dam located on the western side of the lake. Residents have access via a private ramp located along the southern shore. Motors are not permitted. 

Our September 2009 survey found nineteen plant species including the invasive species Eurasian watermilfoil (Myriophyllum spicatum) and minor naiad (Najas minor). Eurasian watermilfoil has been treated with an herbicide and was only found in small patches in the southern end. Minor naiad was the most abundant plant mostly located in the northern half of the lake and also around the lake’s perimeter. Most plant species were found growing along the shoreline with the exception of snailseed pondweed (Potamogeton bicupulatus) and minor naiad which were found growing towards the center. Three transects were examined during this survey. All the plants along these transects were found growing in less than two meters of water.
