The "Organic Act" of August 25, 1916, states that "the Service thus established shall promote and regulate the use of Federal areas known as national parks, monuments and reservations . . . by such means and measures as conform to the fundamental purpose of the said parks, monuments and reservations, which purpose is to conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations." 
Yosemite's Merced River was designated Wild and Scenic in 1987. The supervising agencies were, by law, required to produce a protective management plan within three years. A plan for the lower river was produced on time by the U.S. Forest Service and the Bureau of Land Management. The National Park Service (NPS) has yet to do its part for the 81 miles of the Merced River that flows through Yosemite National Park. While the Yosemite flood of 1997 was a natural process, it caused widespread damage to park infrastructure, including segments of Highway 140. Under the guise of emergency repairs, the NPS decided to widen the canyon road to accommodate larger RVs and commercial buses. The public was horrified by the blasting of 18,000-year-old naturally-formed rock walls, the cutting of oaks, and the filling in of the riparian river bank with rocks and concrete. As a result, in 1999, The Sierra Club and Mariposans for the Environment and Responsible Government (MERG) brought suit against NPS to stop the destruction in the canyon. A portion of the canyon road remains untouched by this road-widening project only because it was stopped by the court. In July 1999, the court found NPS negligent in failing to have a Merced River Comprehensive Management Plan.
