       Bashan Lake is a 273 acre water body located in East Haddam CT.  The lake is moderately developed with residential homes along the shoreline and public access through a state boat launch.

       CAES IAPP has been monitoring Bashan Lake almost every year since 2004 using visual and underwater camera surveys to spot treat for Myriophyllum heterophyllum (variable leaf watermilfoil).  In 2012, IAPP found a population of the invasive species Cabomba caroliniana (fanwort) and preformed suction and hand harvesting methods to reduce the population.  Our 2014 survey only found Myriophyllum heterophyllum in small bunches sporadically throughout the lake and found only a few small patches of Cabomba caroliniana in the southwest corner of the lake

       Our 2014 survey found 19 native species with bladderworts; Utricularia gibba and Utricularia purpurea as the most commonly found species throughout the lake.  Sparganium species, Sagittaria species, Elatine species, and Vallisneria americana were also commonly found along the shoreline.

       In the fall of 2014 Bashan Lake was drawn down approximately 5 m for dam repair and is not expected to be refilled until 2016.
