Conservation Service, The Nature Conservancy, and U.S. Fish and Wildlife Service) is considering a restoration project that could repair the levee as part of its efforts to restore low water flow. To date, two reports on this subject, created by the Center for Watershed Science at the Illinois State Water Survey, are publicly available. Conservation efforts Since the 1970s, efforts have been made to restore the Cache to something more like its historic state. The Citizens Committee to Save the Cache River, a grassroots organization of hunters, fishermen, and nature lovers, enlisted the help of state and federal agencies as well as non-profit groups such as The Nature Conservancy to form the Cache River Wetlands Joint Venture Partnership. During the past 15 years, efforts have been made to control erosion, reduce siltation, stabilize water levels, restore game species habitat, and provide recreational opportunities to the public. One long-term goal of the joint venture is to restore the hydrologic continuity of the Upper and Lower Cache. Over the course of the restoration work, there have been tensions between the conservationists and some local landowners. Some of the region's farmers feared that restoration of the wetlands would cause flooding and loss of agricultural land, and many resented what they perceived as ‘outside influences’ meddling in their communities. Some local sportsmen feared that their favorite hunting and fishing grounds would either be put off limits or else overrun by visitors. State and Federal agencies have attempted at all times to reach compromise with local landowners and sportsmen, but tensions and resentment remain. The Cache offers ample recreation opportunities, such as canoeing, hiking, bird watching, fishing, and hunting. The Henry N. Barkhausen Cache River Wetlands Center interprets the unique natural and cultural history of the Cache River Wetlands. The center also forms the southern anchor to the Tunnel Hill State Trail, which is a favorite with bike enthusiasts. The trail provides an excellent look at the sloughs and bottomland forest as it follows the disused Norfolk Southern Railway grade (originally owned by the Cairo and Vincennes Railroad) from Karnak to Vienna, then continues north through the Shawnee National Forest to Harrisburg, Illinois. The wetland center also contains information about places to hike, canoe, fish, hunt, or watch birds in the Cache River region.
