Trustom Pond is a closed lagoon in South Kingstown, Washington County, Rhode Island, United States.[3] It is one of nine coastal lagoons (referred to as "salt ponds" by locals) in southern Rhode Island.[4][5] It has a surface area of 800 acres (320 ha), and is the only undeveloped salt pond in the state.[6][7] The pond averages 1.3 feet (0.40 m) deep, and has a salinity level of 5 parts per thousand. It is non-tidal, except when breached by storms.[1] The water directly receives about 219,844,022 US gallons (832,200,150 L) of precipitation per year, with an estimated 796,215 US gallons (3,014,000 L) in daily groundwater flow.[8] No streams flow into the pond, though a nearby stream "captures water that otherwise would have flowed to Trustom Pond".[9]

Trustom Pond National Wildlife Refuge is a National Wildlife Refuge, inhabited by over 300 species of birds, 40 species of mammals, and 20 species of reptiles and amphibians.[7] As such, it is a popular bird-watching destination.[10] In 1987, 365 acres (148 ha) of land were donated to the U.S. Fish and Wildlife Service; subsequent donations and purchases raised the protected area to 800 acres (320 ha), with current plans for expansion. The wildlife refuge receives approximately 50,000 visitors annually.[7] The Trustom Pond National Wildlife Refuge includes 3 miles (4.8 km) of foot trails, surrounded by fields, shrublands, woodlands and small freshwater ponds.[11] Wildlife managers create breachways to the Block Island Sound, lowering water levels and creating mudflats which become feeding areas for waders.[12]
