This lake is approx 30 miles NW of NYC, probably named as such because of the "Jackson Whites" who lived there since the 1800's. They are of African and Caucasian descent to varying degrees and also have lineage to the Ramapo, Munsee and Lenape Indians. Just before WW2 it was renamed Negro Pond, since the the 50's it's been known as Potake Lake.
