 SAN JUAN RIVER BASIN SPRING FLOOD POTENTIAL OUTLOOK

The 2018 spring runoff flood potential due to snow melt is lower
than normal at this time. Near record low snowpack exists in early
January throughout much of the San Jan Basin. 
 
As of early January snowpack in the San Juan Basin is near 25 percent of
median above Navajo Reservoir and also 25 percent of median in the Animas
River Basin. 

Seasonal April-July runoff volumes are between 40 and 65 percent of average.

The situation could still change with several months of snow accumulation
season ahead.  

High flows are possible in any year given the right conditions such
as rapidly melting snow or heavy rain that occurs during the snow
melt period.

Further assessment will be made regarding any snow melt flood threat as
the season progresses.
