The preserve was renamed in 2023 to honor G. Thomas Donch, a long-serving local official and advocate for the property.
The lake within the preserve was formerly a private water source before being acquired by the municipality.
The site acts as a critical watershed area for the local Franklin Lakes ecosystem.
The trail system connects to various points of interest around the perimeter of the lake, providing a full loop option.
The land supports a variety of local flora including native hardwood trees and wetland vegetation.
The G. Thomas Donch Nature Preserve, formerly the Franklin Lakes Nature Preserve, is a 120-acre municipal park centered around a 75-acre lake. The property features a network of hiking trails that wind through woodlands and circle the water. It serves as a sanctuary for diverse bird species, making it a local hub for birdwatching. The preserve permits non-motorized boating, such as kayaking and canoeing, on the lake during warmer months. Fishing is permitted in designated areas with a valid New Jersey state fishing license. The terrain is primarily flat, providing accessible walking paths for casual hikers. The preserve is managed by the Borough of Franklin Lakes to maintain local ecological health. It functions as a multipurpose recreational space for walking, jogging, and passive nature observation.
