 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
February throughout much of the San Jan Basin. 
 
As of mid February snowpack is generally below 30 percent of median
for this time of year. Most SNOTEL sites rank in the bottom 2 or
3 of record for this time of year.

Snowmelt peak flow forecasts this spring are expected to be below average at 
this time. April-July streamflow volumes are also likely to be much
below average with recent forecasts ranging between 30 and 50 percent
of average.

While flood related problems are not anticipated at this time due soley to
snowmelt, heavy rainfall can cause flood related issues in any year.

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