Part of the system's Croton Watershed, it lies within the towns of Bedford, Lewisboro, and Pound Ridge, about 1 mile (1.6 km) east of the village of Katonah, and over 25 mi (40 km) north of New York City. It was constructed around the start of the 20th century by impounding the Cross River, a tributary of the Croton River, which eventually flows into the Hudson River. The reservoir was finally put into service in 1908. The resulting body of water is one of 16 (12 reservoirs and 4 controlled lakes) in the Croton Watershed, the southernmost of New York City's watersheds. The reservoir is approximately 3.2 mi (5.1 km) long, has a drainage basin of 30 square miles (78 km²), and can hold 10.3 billion US gallons (39,000,000 m3) of water at full capacity, making it one of the city's smaller reservoirs. To reach the city, water flows through Cross River into the Muscoot Reservoir, then down that one into the New Croton Reservoir, where it enters the New Croton Aqueduct in Yorktown. Via the aqueduct, it flows into The Bronx, entering the Jerome Park Reservoir.

Brookwood Labor College (1921 to 1937) was a labor college located at 109 Cedar Road in Katonah, New York, United States. Founded as Brookwood School in 1919 and established as a college in 1921, it was the first residential labor college in the country. Its founding and longest-serving president was A. J. Muste. The school was supported by affiliate unions of the American Federation of Labor (AFL) until 1928. The Brookwood faculty's emphasis on trade union militancy and on advocacy of socialism was opposed by the AFL's Executive Council, which pressured the AFL's unions to withdraw support for the school. Brookwood was later riven by internal dissent over whether it should support militant unionism or remain strictly an educational organization. Suffering from financial difficulties, Brookwood closed in 1937. It is considered one of the most influential labor colleges in American history and was known as "labor's Harvard."
