Blood, Trauma, and Biohazard Cleanup in Lake Mohawk, NJ

Lake Mohawk is an unincorporated residential development and census-designated place (CDP) in Sussex County, New Jersey, split between Byram Township and Sparta Township, with the community located largely within Sparta.

The community was created in the 1920s by the Arthur D. Crane Company, which bought thousands of acres of farmland at Brogden Meadow and dammed the headwaters of the Wallkill River; the dam was completed in August 1926 and the lake had filled by 1928.

The 800-acre Lake Mohawk reservoir is the largest privately owned lake in New Jersey and is the source of the Wallkill River, which flows north into New York.

The 2020 United States census counted 9,759 residents in the Lake Mohawk CDP, down slightly from 9,916 in 2010.

Census Bureau QuickFacts counts about 3,839 households in Lake Mohawk, averaging 2.47 persons per household, based on 2020-2024 survey data.

The community is administered not by a municipal government but by the Lake Mohawk Country Club, which is governed by a board of trustees.

White Deer Plaza, the community's storybook town center of castle-like Tudor Revival buildings along a tiered lakeside boardwalk, was added to the National Register of Historic Places in 1988 as the White Deer Plaza and Boardwalk District.

An alpine architectural motif runs throughout Lake Mohawk — in its town center, its many homes, and even its spring-fed Alpine Pool, which sits on a higher peak above the main lake.

The community's Marine Pool was built to resemble the deck of an ocean liner like the SS Normandie, and its 1937 filter system made it the first pool in the United States to use corona-discharge ozone to treat its water.

The Lake Mohawk Golf Club set aside 125 acres in the 1920s, opened its first nine holes on August 30, 1929, and today operates as a private par-70, 18-hole course.
