Allamuchy Mountain State Park provides excellent fishing opportunities year round. During the spring the Division of Fish and Wildlife stock the Musconetcong with brown, rainbow and brook trout. Cranberry Lake, Jefferson Lake, Allamuchy Pond and Deer Park Pond contain warm water species such as large mouth bass, sunfish, perch and pickerel.

In  May 17, 2014, the NJ Division of Fish and Wildlife began stocking landlocked salmon in Tilcon Lake to provide anglers with an opportunity to fish for this unique coldwater sport fish close to home. Only a handful of deep lakes in New Jersey have suitable year round habitat for coldwater fish like trout and salmon. Lake Wawayanda in Wawayanda State Park and Lake Aeroflex in Kittatinny Valley State Park are also stocked with salmon.

Tilcon lake can be accessed by parking at the entrance on Kinney Road (named Kennedy Rd. in Google Maps, and which intersects Rt. 604 south of I-80). From the entrance it is a short walk (300 yards over level ground) to the lake.
