                      SPRING FLOOD POTENTIAL 
             FOR THE COLORADO RIVER BASIN WITHIN COLORADO

                         JANUARY 7, 2022

The 2022 spring runoff flood potential due to snowmelt is not high at this time
for the San Juan River basin. It should be emphasized that it is early in the snow
accumulation season and conditions can change before runoff begins.

The current volume forecasts for the April through July runoff period are
below average, ranging between 80 and 100% of average. 

It is important to keep in mind that an extended period of much above normal 
temperatures or heavy rainfall during the melt period can cause or exacerbate 
flooding problems in any year.

The spring runoff potential will be evaluated in early February and an updated
product will be issued at that time.
