Coordinates: 41°16′51.3″N 72°35′50″W / 41.280917°N 72.59722°W Tuxis Pond, occasionally spelled Tunxis, is a small pond located in the town of Madison in New Haven County, Connecticut. The pond is 3.58 acres (1.45 ha) in area. Three small streams run into it, and one runs out to sea. Tuxis Pond is about three feet (0.9 m) above sea level. The shores are mostly rocky with little sand or soil. Many nearby businesses have taken the name of the pond, including a lumber company, bookseller, grill, highway, golf club, art show, and assisted living facility.
The pond was previously known to Native Americans as Tuxisshoag or Tuckshishoag.
The pond is bordered on its western edge by the Tuxis Pond Walkway, an elevated boardwalk that permits viewing of the pond's wetland habitats. The walkway was contentiously approved in 1994 at an initial cost of $350,000, and an additional $400,000 in state funds were secured for the walkway's refurbishment in 2016.
The pond is home to a vast array of fish, amphibians, and reptiles, as well as semi-aquatic mammals and birds. Other native birds and mammals use the pond as well. The most common bird seen there is the piping plover.
The pond is surrounded by trees on most parts, as well as grass and shrubs. The pond itself is host to several varieties of water plants. The areas surrounded by trees are a small, typical New England forest, mainly deciduous trees with some evergreens. The underbrush, too, consists of all the expected grasses, mosses, ferns, and shrubs. The canopy provides adequate shade for some cooler climate lichens. There are many fungi, as well. There are often algal blooms in the warmer months.
