Turkey Hill Brook starts at Turkey Hill Pond, works its way down to Eames Pond (Moore State Park) and eventually joins Caruth Brook to form Thompson Pond. Turkey Hill Brook flows into the Seven Mile River. At one time, this creek had seven dams on it.[2] Thompson Pond comprises approximately 116 acres (0.47 km2). An earthen dam, approximately 150 ft (46 m) in length with a 50 ft (15 m) long concrete spillway, forms the pond.[3]
Caruth Brook drains huge wetlands to the north and west of Thompson Pond.
The Worcester County4-H Club maintains a summer camp, Camp Marshall, on its shores.[4] Camp Marshall was originally built as a Civilian Conservation Corps Camp in the 1930s. In 1948 the state provided a lease for a residential camp program.
