SPRING FLOOD POTENTIAL
FOR THE COLORADO RIVER BASIN WITHIN COLORADO
JANUARY 7, 2021
The 2021 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 45 and 80% 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.
