White Lake Natural Resource Area - Warren County, NJ

The White Lake Natural Resource Area is a beautiful 396-acre preserve located in Hardwick Township. Owned by the County of Warren, the area is managed in partnership with the Ridge and Valley Conservancy for public use and enjoyment. The park's most notable feature, White Lake, is a deep 69-acre spring-fed water body. The lake is named after the white chalky marl bottom which is composed of freshwater mollusk shells and clay.

A variety of habitats surround the pristine lake, including fertile meadows, karst limestone exposures, sinkhole ponds, and stands of mature hemlock and hardwood forests. The shoreline is also home to various endangered or threatened plant species. In addition, the preserve is dotted with several cultural and historical points of interest, including a lime kiln and the stone wall remnants of an ice house/marl processing facility.

Ridge and Valley conservancy use this place as thier own private country club, even if you follow all of the rules above someone always shows up when you are there to let you know what the rules are, they drive you crazy, we pay for this open space in our warren county taxes but we are so restricted on using it. It was a great place at one time it’s a shame
