SAN JUAN RIVER BASIN SPRING FLOOD POTENTIAL OUTLOOK
Flood related issues due to snowmelt are unlikely in the San Juan
Basin this spring. Precipitation in April was again below average
and snow has been melting over the past couple of weeks. The Snowpack
in the San Juan Basin is near 45 percent of average as of early
Some streams in the San Juan Basin have likely peaked. Exceptions
include the Animas Rvier and streams draining the higest elevations.
It`s quesitonable if they will reach levles much higher than what
has already been observed.
Snow melt peaks are expected to be much below average and possibly
less than last season.
Heavy rainfall during the period when stream channel
capacities are reduced due to snowmelt runoff can result in flood
related problems even in low snow years uch as this one.
