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, 1997. 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: Snowpack no longer exists.

NEW MEXICO: Snowpack no longer exists..

UTAH: The potential for snowmelt flooding along the Virgin and Santa Clara rivers is low at this time. Snow water equivalent values were much below average as of May 1. Runoff volumes for April through July are forecast to be much below average and no individual sites are currently forecast to exceed flood stage.
