FLOOD POTENTIAL IN THE UPPER COLORADO RIVER BASIN

The following are generalized discussions of the flood potential due to snowmelt in the Upper Colorado River drainage as of April 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.

COLORADO: The current potential for flooding due to snowmelt in western Colorado is no greater than normal. The snowpack varies from below to near average. Given conditions as of April 1, no forecast points are expected to exceed flood stage.

WYOMING: At this time, the snowmelt flood potential for streams draining the Northeastern Uintas is higher than normal with snowpack in this area much above normal. Elsewhere in this portion of the basin the snowmelt flood potential is currently not high, with the snowpack ranging from below to near normal. At this time no forecasts points are expected to exceed flood stage.

UTAH: Currently, the snowmelt flood potential for the Utah portion of the basin is higher than normal for streams draining the Northeastern Uintas with much above normal snowpack in this area. Elsewhere, the snowmelt flood potential is near normal with the snowpack varying from below normal to above normal, depending upon the subbasin. As of Apri1 1, no forecast points are expected to exceed flood stage.

NEW MEXICO: The snowmelt flood potential over the New Mexico portion of the basin remains below normal. Snowpack for locations upstream of the Four Corners area is below average. Volume forecasts for southwest Colorado streams draining into New Mexico are below average. No forecast points are projected to exceed flood stage due solely to snowmelt during the spring and summer season of 1998.
