New Jersey's hydrology is characterized by a humid climate, with frequent precipitation and abundant water resources. Two major surface flows, the Delaware River and the Hudson River, comprise New Jersey's eastern and western borders respectively. The state has numerous reservoirs and dams that are used for water supply, flood control, and recreation. The largest reservoirs include Round Valley Reservoir and Wanaque Reservoir. The state's major rivers and tributaries include the Passaic River, Raritan River, and Hackensack River, which all flow into the Atlantic Ocean. The state's watershed data indicates that the state experiences variable rainfall and snowpack, with some areas experiencing drought conditions while others are prone to flooding. Overall, New Jersey's hydrology is complex and influenced by a range of factors, including climate variability and anthropogenic activities.
