The site is included on the Illinois Natural Areas Inventory, (Fults Hill Prairie – Kidd Lake Marsh), and is contiguous to the Fults Hill Prairie Nature Preserve, a National Natural Landmark. The Illinois Department of Natural Resources owns and manages both sites. In 2011 HeartLands Conservancy acquired an additional 94.5 acres at this site. Kidd Lake Marsh is one of the most important wetlands within the State of Illinois for breeding species. This property has been deeded to the Illinois Department of Natural Resources for long-term ownership and management.

The original Kidd Lake was a shallow body of water which was then partly drained and is now being farmed. The remnants of the lake contain a thick stand of bulrush, cattail, and smartweed. Willows are found in the drier portions of the marsh and a few small ponds of open water occur in the area.

In the spring visitors will be able to listen to a number of different frogs looking for mates in early spring make a lot of noise on warm humid nights. In the winter dome-shaped mounds can be seen throughout the marsh are muskrat houses. Kidd Lake State Natural Area is a primitive area primarily devoted as a home to wildlife. There are no man-made improvements to provide visitors easy access to the area such as trails, parking lots, etc.
