Transect Data | Water Data

  Coventry Lake is a 373-acre waterbody located in Coventry, Connecticut first surveyed in 2008. The lake is used publicly for recreation and is heavily developed with summer and year round homes.

       The CAES IAPP 2014 survey found 24 species in Coventry Lake. This is an increase from the 19 species found in 2008. Similar to 2008, the 2014 survey identified two invasive species, Eurasian watermilfoil (Myriophyllum spicatum) and curlyleaf pondweed (Potamogeton crispus). Six new species were identified including slender watermilfoil (Myriophyllum tenellum), southern naiad (Najas guadalupensis), and large-leaf pondweed (Potamogeton amplifolius). Slender watermilfoil and southern naiad were both found mostly along the shoreline while large-leaf pondweedwas frequently found throughout the whole littoral zone.

       Eelgrass (Vallisneria americana), found in both the 2008 and 2014 survey, was the most commonly found native plant covering much of the littoral zone. Eurasian watermilfoil was also regularly found mainly located in large patches throughout the lake.Both plants have increased in acreage since the 2008 survey. Only a small quantity of the invasive species curlyleaf pondweedwas found in one location on the lake.
