Long Meadow Pond has a surface area of 100 acres. It has a maximum depth of 7 feet and an average depth of 4.2 feet. At the northern end of the lake is an earthen dam. With the exception of the northern half of the eastern shore that is forested, the area around Long Meadow Pond is mostly developed. Public boat access is controlled by the Long Meadow Pond Association.

The 2012 survey of Long Meadow Pond was a resurvey from 2005. The 2012 survey found the presence of 19 species of plants with one invasive, minor naiad (Najas minor).  It was found in two locations in the north end of the lake along the earthen dam. The 2005 survey did not find minor naiad but did find another invasive not found in the 2012 survey, curlyleaf pondweed (Potamogeton crispus). Long Meadow Pond was treated for nuisance plants, including curlyleaf pondweed, this summer only a few weeks prior to our survey. This could be why it was not found during the survey.

Three floating leaf plants were found to be the most dominant plants in the lake: watershield (Brasenia schreberi), yellow water lily (Nuphar variegata), and white water lily (Nymphaea odorata). They covered the surface of the water near the shore. They grew most densely north of the island. This coincides to where the treatment area starts and ends. The most species dense area of the lake was north near the dam. All species except water plantain (Alisma species) and eelgrass (Vallisneria americana) were found there. Most of the species rich areas were north of the island, where treatment did not occur and also the portion of the lake not developed. South, where there is a town beach and development of houses, the plants did not seem to be growing at a level that impeded recreational activities.
