Gila River near Clifton (09442000) May 18, 1980
Raymond M. Turner Large floods in the 1970s scoured much of the floodplain, but most of the larger riparian plants remain and are larger. The largest flood, in 1979, had a discharge of 57,000 ft3/s, which is the flood of record at this station (record: 1911-1917, 1928-present). If the trees were not destroyed or damaged during the floods, they benefitted from the increased water infiltrating into the floodplain. The gaging station, which was moved from a site nearby, now appears on the upstream side of the bridge at far right.
