 SAN JUAN RIVER BASIN SPRING FLOOD POTENTIAL OUTLOOK

The 2019 spring runoff flood potential due to snow melt is lower
than normal at this time. Near to below normal snowmpack exists throughout
the San Juan River Basin.

As of early February snowpack in the San Juan Basin is near 95 percent of
the historical median above Navajo Reservoir near the historical median in the Animas River Basin.

Seasonal April-July runoff volumes are between 55 and 85 percent of average,
but are likely to increase due to recent and future storms.

While flooding to solely to snowmelt isn`t a frequent occurence in much
of the San Juan Basin, high flows are possible in any year due to
heavy rainfall or rainfall combined with melting snow.

It is still early in the snow accumulation season and the outlook
may change. Further assessment will be made regarding any snow melt flood
threat as the season progresses.
