Republican congressional majorities weakened after the 1926 elections. The 70th Congress (1927–1929) tackled a number of natural resources initiatives: flood control along the Mississippi River; a survey of national forest reserves; and a dam project along the Colorado River. President Calvin Coolidge again vetoed the McNary—Haugen farm-subsidy bill and later pocket vetoed a bill to complete a major government power facility at Muscle Shoals, Alabama, in the Tennessee Valley.
