FLOOD POTENTIAL IN THE Lower Colorado River Basin

The following are generalized discussions of the flood potential due to snowmelt in the Lower Colorado River drainage as of May 1, 1998. Discussions are segregated by state. It is important to understand that the potential for flooding may increase dramatically if snowmelt accelerates rapidly due to above normal temperatures or if significant rain events occur.

ARIZONA: Due to depleted snowpacks, there is virtually no potential for flooding at this time solely due to snowmelt.

NEW MEXICO: Due to depleted snowpacks, there is virtually no potential for flooding at this time solely due to snowmelt.

UTAH:. A higher than usual snowmelt flood potential exists along the Virgin and Santa Clara rivers at this time. Snow water equivalent values were much above average as of May 1 but flooding due solely to snowmelt is not expected. Runoff volumes for April through July are forecast to be above average, with no individual sites currently forecast to exceed flood stage.
