Mazonia State Fish and Wildlife Area consists of 1,017 acres and is located in Grundy County 3 miles southeast of Braidwood on Illinois Route 53 and Huston Road.


Braidwood Lake, owned by Commonwealth Edison, is a partially perched, cooling lake. Constructed in the late 1970s Braidwood Lake was impounded in 1980-81 with water pumped from the Kankakee River. Several surface mined pits were flooded within the lake, so fisheries management actually began in 1978 before the lake existed. The lake was considered a semi-private area used by employees of Com Ed till the fall of 1981 when the Department of Conservation (now the Department of Natural Resources) acquired a long term lease agreement from Com Ed allowing for general public access. Braidwood Lake currently is used for fishing, waterfowl hunting, fossil hunting by permit and as a waterfowl refuge.

Existing Resources

The area contains more than 200 water impoundments ranging from 3/4 to 30 acres in size. Anglers may try their luck catching largemouth bass, smallmouth bass, bluegill, green sunfish, crappie, channel catfish and bullhead. Additional species will be stocked as the site is developed. Good wildlife habitat can be found on the site in the 700 acres of grassland, brushy draws and limited woodland cover.

Area Objectives

Mazonia is managed primarily for sport fish and waterfowl. Its purpose is to provide a quality sport fishery within the surface-mined lakes through habitat enhancement and supplemental stockings which, in turn, will provide the public quality bank and boat sport fishing opportunities. The site also will provide quality mid-migration and resident waterfowl habitat, including food, water and sanctuary components, and resultant quality waterfowl hunting opportunities.

The area also is managed for other resident or migratory game and non-game fish and wildlife species, particularly those listed as threatened or endangered.

Although Mazonia features sport fishing and waterfowl hunting, a variety of other outdoor recreational opportunities are provided throughout the year. Upland game hunting, furbearer trapping, limited picnicking, nature study/birding, fossil hunting and water dog training also are available.


While minimal facilities are available, future development will include a paved access road to the main lakes, boat launches, ramps, parking lots and toilets.

Hunting and Fishing

Fishing and hunting are permitted on a seasonal basis and are subject to site regulations. Fishing closes 10 days prior to the central waterfowl zone season and reopens at the conclusion of the upland game season, or as the ice becomes safe.

Mazonia South Unit

The Mazonia South Unit was purchased by DNR from Commonwealth Edison in 1999. This was the first acquisition under the landmark Open Land Trust, a program that sets aside dollars to be used to purchase acreage for multiple purpose recreation and to protect open space for future generations.

The land making up the south unit was formerly surface mined, resulting in rugged terrain, four large lakes and 10 smaller water impoundments that contain excellent fish populations. Access to most of the water will be available via boat launches, while some of the smaller lakes will be walk-in only. The area will be used for fishing, wildlife habitat, hunting and other recreational activities.

Braidwood Lake Site Locations

Braidwood Lake Fish and Wildlife Area consists of 2,640 acres and is located in Will County south of Braidwood off Illinois Route 53.


Braidwood Lake can become very dangerous and special precautions should be utilized. A wind warning system is in place by a flagpole located at the Cemetery Boat Ramp and the Kankakee Boat Ramp. The flag system displays predicted weather conditions for that day. Different colored flags will be raised to depict the weather conditions. The lake will be closed with 25 MPH winds.

Boats with a minimum length of 14 feet are recommended. Motor size is unlimited but a 40 MPH speed limit is strictly enforced.

Fossil Collecting

Mazonia is well known for Pennsylvanian age fossils. A day permit is required to collect fossils and may be obtained from the park office or Web site. A reporting form also is available for reporting what was found. Excavations and collecting for commercial purposes are prohibited. In addition, fossil collecting is restricted to March 1 to September 30.

  • While groups of 25 or more are welcome and encouraged to use the park's facilities, they are required to register in advance with the site office to avoid crowding or scheduling conflicts.
  • At least one responsible adult must accompany each group of 15 minors.
  • Pets must be kept on leashes at all times and clean up after them.
  • Actions by nature can result in closed roads and other facilities. Please call ahead to the park office before you make your trip.
  • We hope you enjoy your stay. Remember, take only memories, leave only footprints.
