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, 2000. Discussions are segregated by state. It is important to understand that the potential for flooding may increase if significant rainfall events occur.

 

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

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

UTAH: The potential for snowmelt flooding along the Virgin and Santa Clara rivers is not high at this time. Snow water equivalent values as of May 1 were 40% of average. Runoff volumes for the April to July period are forecast to be much below average and no individual sites are expected to exceed flood stage.
