Pompton Lakes is a borough in Passaic County, New Jersey, United States. As of the United States 2000 Census, the borough population was 10,640. Pompton Lakes was formed as a borough on February 26, 1895, from portions of Pompton Township, based on the results of a referendum held three days earlier. Pompton Lakes was the first borough to be formed in Passaic County, as the "borough fever" that had struck elsewhere hit the county. The newly-formed borough did not acquire territory from more than one township, which would have entitled Pompton Lakes to a seat on the Board of Chosen Freeholders. Three rivers, the Ramapo, Pequannock and Wanaque, run through the Borough, providing many relaxing year-round activities for Pompton residents.
