SAN JUAN RIVER BASIN SPRING FLOOD POTENTIAL OUTLOOK
The flood potential due to snowmelt is considered lower than normal in the
San Juan Basin as of early April. Snowpack conditions are less than 50 percent
of the historical median in much of the San Juan Basin. Some SNOTEL sites are
reporting snowpack conditions less than 30 percent of median as of early
April. Snowpack conditions typically peak by mid April and significant
additional snow accumulation is unlikely beyond that time
Peak flow forecasts in the San Juan Basin call for mean daily peaks
that are less than half of the average spring peak flow. These forecasts
are also less than half of what was observed last spring.
Flood relates issues due to heavy rainfall are possible in any year,
however flood issues due solely to snowmelt runoff are not anticipated for
this runoff season.
Specific peak flow forecasts can be found on the Colorado Basin River
Forecast Center website at: https://www.cbrfc.noaa.gov/rmap/peak/peaklist.php.
These forecasts are updated the first of each month and more frequently if needed.
