This bill establishes the Benjamin Harrison National Recreation Area and Wilderness as a new protected area within Indiana's Hoosier National Forest, consisting of approximately 29,382 acres designated for recreation and 15,300 acres added to the existing Charles C. Deam Wilderness. The legislation affects Indiana residents, outdoor enthusiasts, and local communities by protecting water quality in Monroe Reservoir while maintaining hunting, fishing, camping, hiking, mountain biking, and other recreational uses in the areas. The Forest Service must develop a comprehensive management plan within five years in consultation with an advisory committee composed of local officials, conservationists, recreation experts, and tribal representatives. The bill contains no new federal funding requirements, instead directing the Forest Service to use existing appropriations, and it preserves existing rights for private property owners, utilities, and emergency services operating within the designated areas.
