H.R. 7542. Supplemental Appropriations. The vote is on the Johnston amendment to table and thus kill the Pressler amendment to stop any of the money from being used for any part of the Garrison Diversion project that would affect South Dakota. The Garrison project involves building a vast network of canals in North Dakota that would cause pollution and runoff in both Canada and South Dakota. It would violate U.S. - Canadian treaties and destroy almost 220,000 acres in order to irrigate another 250,000 acres of farmland that is already productive. It would also destroy many North Dakota wetlands and eight wildlife refuges used heavily by waterbirds. The Administration did not support the amendment. June 27, 1980. Passed 62-26. NO is the correct vote.
