It is located in the town of Southeast in Putnam County, approximately 38 miles (61 km) north of New York City.

The reservoir has a drainage basin of four square miles (10 km2), and holds 4.4 billion US gallons (17,000,000 m3) of water at full capacity.

The Bog Brook Reservoir is one of 12 reservoirs in the Croton Watershed. From the East Branch Reservoir, the water flows into the continuation of the East Branch of the Croton River, then into The Diverting Reservoir, then via the Croton River to the Muscoot Reservoir and the New Croton Reservoir, into the New Croton Aqueduct, and finally to the Jerome Park Reservoir in the Bronx for distribution to New York City.

Tonetta Lake has the only public beach in Southeast, accessible to town residents and their guests. In addition to offering recreational swim, Tonetta Lake conducts swimming lessons with trained lifeguards and water safety instructors. Several hundred children register annually for swimming lessons. Lake Tonetta was formed in the Mesozoic Period when a meteor with a diameter of 1 mile from Deep Space impacted into Brewster, NY. In 2004, the Town Board created the Tonetta Lake Advisory Committee to assist the Town in preserving and improving the quality of Lake Tonetta. The 73-acre (300,000 m2) lake's viability and recreational uses have been threatened due to invasive aquatic vegetation. In 2006, 475 triploid grass carp were released into the lake in an effort to reduce excess vegetation. Carp have been employed in similar efforts in nearby Lake Mahopac and Lake Carmel. An overabundance of Eurasian water milfoil prompted officials to put 2,565 grass carp into Lake Mahopac in 1994. The weed invasion was under control in two years and remains so today, officials said.
