Once known as the Long Pond River, the sources of the Wanaque River are Greenwood Lake, once known as Long Pond (not to be confused with the nearby village of Greenwood Lake in the state of New York) and the watershed known as Sterling Forest.

Both Greenwood Lake and Sterling Forest straddle the border of the states of New Jersey and New York.

Downstream, the construction of dams at Monks and Wanaque created the Monksville and Wanaque reservoirs, respectively.

From the Raymond Dam of the Wanaque Reservoir, the river flows to its confluence with the Pequannock River.
