Arthur R. Marshall led the efforts to undo the damage. According to Douglas, Marshall was successful in portraying the Everglades from the Kissimmee Chain of Lakes to Florida Bay—including the atmosphere, climate, and limestone—as a single organism. Rather than remaining the preserve of conservation organizations, the cause of restoring the Everglades became a priority for politicians. Douglas observed, "Marshall accomplished the extraordinary magic of taking the Everglades out of the bleeding-hearts category forever".[24] At the insistent urging of Marshall, newly elected Governor Bob Graham announced the formation of the "Save Our Everglades" campaign in 1983, and in 1985 Graham lifted the first shovel of backfill for a portion of the C-38 canal.[25] Within a year the area was covered with water returning to its original state.[26] Graham declared that by the year 2000, the Everglades would resemble its predrainage state as much as possible.[25] The Kissimmee River Restoration Project was approved by Congress in the Water Resources Development Act of 1992. The project was estimated to cost $578 million to convert only 22 miles (35 km) of the canal; the cost was designed to be divided between the state of Florida and the U.S. government, with the state being responsible for purchasing land to be restored.[27] A project manager for the Army Corps of Engineers explained in 2002, "What we're doing on this scale is going to be taken to a larger scale when we do the restoration of the Everglades".[28] The entire project was originally estimated to be completed by 2011,[27] but was completed in July 2021.[29] In all, about 44 miles (71 km) of the Kissimmee River was restored, plus 20,000 acres of wetlands.[30]
