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, 2000. 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: In many areas, peak forecasts have been raised from those issued last month. Overall, the snowpack increased 5% to 20% of average during March and, as of April 1, was near average in most of western Colorado except the San Juan Basin. A this time, the Yampa River around Steamboat Springs is expected to rise to near flood stage; no other points are expected to be near flood stage.

WYOMING: The snowmelt flood potential for streams in southwest Wyoming is not high at this time. The April 1 snowpack varies from slightly below to slightly above normal. As of April 1 no forecast points are expected to exceed flood stage due solely to snowmelt.

UTAH: Currently, the snowmelt flood potential for the Utah portion of the basin is not high with the snowpack varying from near normal to much below normal. As of April 1, no forecast points are expected to exceed flood stage due solely to snowmelt.

NEW MEXICO: The snowmelt flood potential over the New Mexico portion of the basin is low at this time. Snowpack for locations upstream of the Four Corners area is below average. Volume forecasts for southwest Colorado streams draining into New Mexico are much below average to average. No forecast points are projected to exceed flood stage due solely to snowmelt during the spring and summer season of 2000.
