Canoe Brook Lake, Trumbull - 2012
Canoe Brook Lake is a 63.7-acre waterbody located in Trumbull. It is a private lake with no public access and is maintained by the Canoe Brook Lake Association. The association maintains a water testing program and a website that provides information on ways to protect the environmental quality of the lake (Canoe Brook Lake Association). The lake association now maintains four beaches and a boat launch (all boat motors are prohibited) for members.
The CAES IAPP 2012 survey of Canoe Brook Lake was a resurvey from our initial survey in 2004.In 2004, ten species of aquatic plants were found with one species being invasive, minor naiad (Najas minor).The most dominant species in 2004 was a native, slender naiad (Najas flexilis). The 2012 survey of Canoe Brook Lake found 16 species of aquatic plants with the same invasive found in 2004, minor naiad. Minor naiad was found growing in a high to low abundance around the majority of the shoreline. Slender naiad was found frequently growing with minor naiad but at a lower abundance.It appears that minor naiad may be displacing slender naiad.
The most dominant species in the lake was the native eelgrass (Vallisneria americana). Eelgrass was found growing in medium to high abundance around most of the lake.The largest patch was found on the center of the eastern shore.This patch extended halfway across the lake and grew along approximately 1/3 of the coast.
Similar to 2004, the most species rich area of the lake remained in the northern portion. Seven species were found in 2004 while 11 species were found in 2012. Those found in 2012 but not in 2004 included water starwort (Callitriche species), primrose-willow (Ludwigia species), snailseed pondweed (Potamogeton bicupulatus), spikerush (Eleocharis species), arrowhead (Sagittaria species), and waterwort (Elatine species). Low watermilfoil (Myriophyllum humile) and western waterweed (Elodea nuttallii) were found in the 2004 survey but not in the 2012. In 2004, the most common growing plant in the northern tip was western waterweed. In 2012, all the species could be considered growing co-dominantly in that same area..
