What is the Niantic River Watershed?  

The Niantic River watershed is all the land that drains to the Niantic River.  Local water features such as Fairy Lake, Horse Pond, Barnes Reservoir, Bogue Brook Reservoir, Lake Konomac, Darrow Pond, Latimer Brook, Oil Mill Brook, Stony Brook as well as the Niantic River itself, are all part of what is called the Niantic River Watershed.  The watershed covers 31.3 square miles, or approximately 20,000 acres and includes areas from the four towns of East Lyme, Waterford, Salem and Montville.  For more information on watersheds, visit the US EPA’s Watershed web page: http://water.epa.gov/type/watersheds/index.cfm.  

   

   

The Niantic River Estuary  

The Niantic River is an estuary.  Fresh water drains from a small coastal watershed to a tidal embayment where fresh water mixes with the salt water of Long Island Sound.  Many people relate to the Niantic River as a body of saltwater that provides access to the Sound and to a rich variety of marine resources.  Others make connections to local freshwater streams and ponds through recreational activities such as fishing and swimming.  For citizens of Waterford, including Quaker Hill, and New London, the freshwater resources in the watershed provide drinking water to 13,000 homes and businesses.   

The shallow marine estuary of the Niantic River was formed when sea level was at an elevation high enough to flood the low lying coastal valley.  The river has historically supported healthy populations of shellfish, crustaceans, and finfish and also provides excellent bird habitat as ospreys, herons, kingfishers, and cormorants may be observed at various times throughout the year.  A fish ladder installed in Latimer Brook just north of I-95, allows the passage of species such as alewives and sea-run trout to spawning areas upstream.  Visit http://www.ctriversalmon.org/runs.html for information, fish counts and video clips of the fish ladder and fish runs.

 Migratory Birds  

 According to Min Huang, CT DEEP Migratory Game Bird Program Leader, the Niantic River harbors relatively large concentrations of resident mallards, Canada geese, and feral mute swans throughout the year.  The largest concentrations of resident waterfowl are typically found in the upper reaches of the river.   

These birds will stay in the upper reaches of the river until ice forces them further downstream.  In the fall, winter, and early spring the lower river holds large numbers of wintering diving ducks such as hood mergansers, bufflehead, and red-breasted mergansers.  The bay, south of RT 156, attracts large flocks of Atlantic brant and, to a lesser extent, common goldeneye during the winter months.   

    

Oswegatchie Hills  

In East Lyme, the area known as Oswegatchie Hills consists of over 700 acres of valuable land that offers great recreational potential because of its interesting terrain and diverse wildlife.  It is also one of the largest stretches of undeveloped waterfront land in Connecticut.  The Waterford shoreline along this reach consists mainly of sandy beaches and gradual wooded slopes with moderate density residential development.
