Facilities & Activities:


Nine miles in length and covered by 2,500 acres of freshwater, Lake Hopatcong is the focal point of the park. Hopatcong State Park is at the southwest end of the lake and is a popular spot for fishing, boating, and swimming.

Lake Hopatcong was originally created as part of the Morris Canal, a 90-mile waterway that ran from Newark to Phillipsburg and was the chief means of transporting coal, iron and zinc across New Jersey in the 1860s. The lake was the canal’s major source of water. In 1866, over 880,000 tons of freight was transported on the canal.

However, as the more efficient Morris and Essex Railroad was established, the canal was abandoned. The historical museum is located in the old Morris Canal locktender’s house and offers exhibits on local American Indian history, the Morris Canal and the history of the lake.

Per the Water Level management plan we will begin the annual drawdown of Lake Hopatcong on December 7, 2016. This year we will drop the lake to 22 inches as part of a pilot project effort to assist in lake refill in the Spring.  Also note that after reaching 22 inches, due to the drought warning that we are in, that the outflow will be reduced from 12 c.f.s to 8 c.f.s. As always, State Park personnel will carefully monitor this drawdown.

Lake Hopatcong Water Level Management NJDEP Proposal

LAKE HOPATCONG DOCK SURVEY - In the Fall of 2014 Professor Lisa Jordan of Drew University and two of her students, Maxwell Dolphin and Daniel Ratyniak, completed a survey of all docks and associated parcels on Lake Hopatcong.  The survey includes such information as dock lengths, parcel lots and blocks, street address, property owner names, etc.  The survey was performed in conjunction with the State Park Service (SPS), and the Lake Hopatcong Foundation. 

The survey is important to the SPS in that it provides baseline data as SPS reviews dock construction permit applications, and for the current dock regulation committee, which is reviewing SPS regulation of dock lengths on the Lake.  Having this baseline data may also prove useful for future applications.

The full report, "A Summary of Docks on Lake Hopatcong", can be accessed at  Full access to dock study results is available via website links found on page 11 of the study, though a review of the full report is very valuable.

The SPS thanks Dr. Jordan and her students for such a thorough study, as well as the Lake Hopatcong  Foundation for coordinating the effort.

Fish and Wildlife Stream Classification

The Morris Canal

Bergen, Essex, Morris, Sussex, Warren Counties

Completed in 1837, the Morris Canal was an engineering landmark that relied on canals, locks and inclined planes to lift and carry canal boats from Phillipsburg on the Delaware River to Jersey City, the Hudson River and New York Harbor. The boats transported coal, iron ore, manufactured goods and agricultural produce. Sections of the canal are administered by Hopatcong State Park.

Lake Musconetcong

During the mid-1800s, the Morris Canal and Banking Company created Lake Musconetcong as an additional water source for the Morris Canal. This lake, which is located four miles west of Lake Hopatcong, was deeded over to the State of New Jersey with the other parts of the Morris Canal System in 1924. Today boating, fishing and ice fishing are popular recreational activities on this lake.


Both Lake Hopatcong and Lake Musconetcong offer excellent year-round fishing. During the spring the New Jersey Division of Fish and Wildlife stocks both lakes with brown, rainbow and brook trout. Warm water species commonly caught are large mouth bass, sunfish, catfish, perch and pickerel. During the winter months, both lakes provide excellent ice fishing for perch and pickerel. Fishing is subject to New Jersey Division of Fish and Wildlife regulations.
