Swartswood Lake provides tranquil surroundings and opportunities for recreation in a natural rural setting.
Purchased in 1914 for public enjoyment, Swartswood Lake has been attracting visitors long before it was established as a state park. This remote and rural area is off the beaten path and away from all major highways, but worth finding. Don’t expect jet skis or gas-powered motorboats racing across the 519-acre natural glacial lake as only electric motors are permitted. Instead, expect views of colorful sailboats, canoes and kayaks on the still waters of Swartswood Lake. As a bonus, Little Swartswood Lake offers all of the same on a smaller scale (except swimming), just minutes away by car or a short hike. Bring binoculars for a close view of the many resident bald eagles frequently seen flying over the lakes as well as other birds of prey and waterfowl. So, pack your gear for the day or weekend and take advantage of all the opportunities the natural landscape has to offer.
The lake became popular as a summer resort in the late 1800s for urban dwellers seeking respite in a tranquil rural environment. Visitors travelled by horse-drawn carriage, railroad and eventually by automobile to reach the shores of Swartswood Lake. Small cottages, tent platforms and boarding houses occupied the shoreline. Canoes, sailboats and even a steamboat provided leisurely transport on the pristine 519-acre lake. It later became the perfect location for New Jersey’s first state park. It all started with just 10 acres donated by George M. Emmons and his wish ” …that the people may have the use of the premises conveyed as a public park forever…” The lake was purchased in 1914 for $30,000 from Andrew Albright, a wealthy Newark manufacturer, who would not allow public access without payment of one dollar each day. Public outcry prompted the State to pursue the acquisition. Swartswood was established as New Jersey’s first state park in 1915 to ensure public access to the State’s third largest freshwater lake.
The formation of Swartswood Lake began more than 10 million years ago when the limestone and dolomite beneath the valley floor began to dissolve, causing the creation of sinkholes and caverns. Eventually, Swartswood Lake was created as retreating glaciers eroded and scoured the area over 10,000 years ago.

The lakes are an important ecological and recreational resource. Visitors come from all around for an opportunity to go swimming, boating or fishing in these lakes. Many just come to relax along the shores. The lakes are also home to a healthy bald eagle population. Daily sightings of a mature or immature bald eagle are common.
Protecting the health of these lakes requires managing their watershed area. Swartswood’s watershed is 11,218 acres/16.3 square miles. Through New Jersey’s Green Acres Program, thousands of acres have been acquired for the primary purpose of watershed protection.
Lakes go through a natural aging process. If left undisturbed, a lake can age and change naturally over thousands of years. However, our lakes are naturally productive, high in nutrients and greatly impacted by human activity within the watershed area that drains into the lake. This combination accelerates the aging process and requires a more aggressive approach to promote biodiversity and maintain a healthy ecosystem. With the help of our partners, the Swartswood Lakes and Watershed Association and other stake holders, we have been successful in adopting an effective integrated approach to lake management. This includes mechanical, biological and chemical methods to control the growth of invasive aquatic weeds while providing the opportunity for native plants to thrive.
Near the outlet of Swartswood Lake is Keen’s Gristmill, built in the 1930s on the site of several earlier mills. The earliest mill dates back to the Revolutionary War. The mill was used to grind locally grown corn into meal. The structure was acquired by the State in July 1976.
Another symbol of the area’s rich history in the grinding of locally-grown grain is the Stillwater Gristmill. Located along the Paulinskill River on Main Street, the mill was rebuilt in 1844 after a fire destroyed the previous structure built in 1776. The mill and surrounding property was purchased by the State and assigned to Swartswood State Park in 2006. Thanks to the Historical Society of Stillwater Township, the mill and surrounding property are now listed in the State and National Register of Historic Places.
In October 2000, the NJ Department of Environmental Protection added 444 acres of Swartswood State Park to the State’s Natural Area System, making it the 43rd designated Natural Area. The area was designated for the preservation of rare sinkhole ponds, pond shore vegetation communities and numerous known occurrences of rare plant and animal species.
