                      SPRING FLOOD POTENTIAL 
             FOR THE COLORADO RIVER BASIN WITHIN COLORADO

                        May 5, 2020

The 2020 spring runoff flood potential due to snowmelt is not high at
this time for San Juan River basin. Flooding due to solely snowmelt is
unlikely as the snow accumulation season has basically ended, snowpack
conditions are well below average for most areas in early May, and many 
locations within the San Juan River basin have already experienced
significant snow melt. 

Precipitation and snow conditions as of May 1st are listed below.

PRECIPITATION (% OF AVERAGE) AND SNOWPACK (% OF MEDIAN):

SUBBASIN                 APR PRECIP     OCT-APR PREC    MAY 1 SNOWPACK
----------------------   ----------     ------------    ---------------

While flooding due solely to snowmelt is not likely at this time,
flood related problems can result in any year if heavy rainfall
occurs during the melt period when channel capacities have been
reduced.
