Salt River Near Roosevelt (09498500), November 25, 2000
Dominic Oldershaw, Stake 955
Flood frequency on the Salt River didn't change significantly
in the 20th century, as it did on other rivers in the region, although four
100-year floods did occur in a 15-year period. The 1993 flood, which had a
peak discharge of 143,000 ft3/s at the gaging station on the bridge
visible in the distance, did little to slow the advance of riparian vegetation---particularly
tamarisk---at this site. Native species, notably phragmites, have also increased,
although they are difficult to distinguish from the tamarisk at this location.
