Northeast Aquatic Research (NEAR) was contracted by the Lake Wononscopomuc Association (LWA) in 2025 to investigate the water quality, assess the aquatic plant community, and make recommendations for management and ongoing monitoring of Lake Wononscopomuc. In April, NEAR staff trained an LWA volunteer on how to conduct water quality monitoring. In May, August, and September, LWA volunteers performed the water quality sampling. In June, July, and October, NEAR staff performed the sampling. Each month, data and water samples were collected from the site of deepest water (~101 feet/~30 meters) labeled as Station 1 (Map 1). During each visit, water clarity was measured with a Secchi disk and view scope. Water temperature and dissolved oxygen profiles were measured with an in-situ probe at one-meter increments from top to bottom. Water samples were collected from the top (1m), middle (15m), and bottom (30m) depths for analysis of total phosphorus, total nitrogen, nitrate nitrogen, and ammonia. During NEAR sampling months, one phytoplankton sample and one zooplankton sample were collected. LWA volunteers additionally sampled Belgo Brook and Sucker Brook on eight occasions. Map 1 depicts the locations of Station 1 and the inlets. On five occasions, NEAR searched the entire littoral zone of the lake for Hydrilla (Hydrilla verticillata), an invasive plant present in nearby waterbodies. Additionally, NEAR conducted a rare plant survey on June 20th, specifically searching for plants listed as “protected” by the State of Connecticut. There are records of two State-listed protected species in Lake Wonononscopomuc.
