Upper Moodus Reservoir, East Haddam - 2016
Upper Moodus Reservoir is a 440-acre waterbody located in East Haddam, CT. It is a public lake with access on the northwestern portion of the reservoir. The reservoir has an impoundment separating Upper and Lower Moodus on the north end. There is a 35 MPH speed limit during the day and an 8 MPH speed limit between 9 p.m. and 8 a.m. The reservoir is highly developed on the western half with little development on the eastern half.
The CAES IAPP 2016 survey of Upper Moodus Reservoir was a resurvey, and year to year comparisons were provided to stakeholders in a formal report. The first survey was conducted in 2012. The 2016 survey found 37 aquatic species, three were invasive: fanwort (Cabomba caroliniana), variable-leaf watermilfoil (Myriophyllum heterophyllum), and curlyleaf pondweed (Potamogeton crispus). The abundance of fanwort and variable-leaf watermilfoil decreased dramatically since 2012, probably because of a targeted herbicide application. Curlyleaf pondweed maintained a small abundance in three different areas throughout the reservoir, similar to 2012.
