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 April 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: The potential for snowmelt flooding in Arizona is low at this time. Snow water equivalent values were much below median in the Salt, Verde, and Little Colorado river basins as of April 1. Runoff volumes for April through May are forecast to be much below median in all basins. No individual sites are forecast to exceed flood stage.

NEW MEXICO: The potential for snowmelt flooding on the upper Gila River and on the Little Colorado River drainage in New Mexico is also low at this time. On April 1 snow water equivalent was below median in the Gila River Basin. The April through May runoff volumes are forecast to be much below median with no individual sites forecast to exceed flood stage.

UTAH: The potential for snowmelt flooding along the Virgin and Santa Clara rivers is not high at this time. Snow water equivalent values were much below average as of April 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.
