This year’s spring and summer drought outlook may be tough to predict, but currently the state’s northern mountains and Front Range look strong. There are increasing concerns of dry conditions along the Eastern Plains, in the southwest and San Juans where we are seeing slightly below average snowpacks and reservoir levels. There are reports of extremely dry subsoils on the Eastern Plains. Precipitation averages statewide have slipped from 95 to 90% of average statewide since mid-February. Statewide snowpack has decreased from 110% to 104% since mid-February. Streamflow forecasts are already showing the implications of dry autumn precipitation with forecasts ranging from 54% (Surface Creek near Cedaredge) to 132% (Spinney Reservoir Inflow) of median streamflow values.
● The 90-day Standardized Precipitation Index (SPI) (from Dec 18 to Mar 17) shows below average moisture for the SW and NE and distributed average or slightly above for the central and north mountain regions.
● The U.S. Drought Monitor, released March 19, shows worsening conditions in NE Colorado. D0 (abnormally dry) conditions cover 25% of the state; D1 (moderate) covers 42%; D2 (severe) drought covers 3% of the SE and SW corners; and 30% of the state (north-central) remains drought free.
● ENSO forecasts are still trending toward neutral conditions for spring and summer 2020.
Colorado Drought Monitor March 17, 2020.
● NOAA’s Climate Prediction Center three month outlook maps show increased probability for warmer than average temperatures March through May for much of the state, and equal chances of near, above, or below average precipitation outlooks.
● Reservoir storage remains near to above normal: 84% to 123% of average in all major basins and 107% of average statewide. Last March 2019, statewide reservoirs were at 83% of average.
● SNOTEL Snow Water Equivalent (SWE) sites show statewide snowpack at 104% of record median (as of Mar 19).
● Water providers and water users did not report any unusual impacts or concerns at this time.

These days the Arkansas River doesn’t seem threatening as it ripples past Pueblo’s historic district. But in early June of 1921, it was a very different story. That’s when days of heavy rains combined with mountain snowmelt to catastrophic results…
Locomotives and train cars were responsible for a lot of damage; more than 1,200 were washed away, smashing through buildings. There were fires and vast amounts of mud. Telephone lines were out, leaving Pueblo cut off from the rest of the world. And the city was littered with the corpses of livestock, adding to public health concerns.
When the floodwaters receded, Puebloans got to work to make sure it wouldn’t happen again. The engineers literally moved the Arkansas River about a half-mile to the southwest and built a massive levee to protect the city.
The former river channel through downtown languished for decades, becoming an eyesore for the city…
More than fifty years after the flood, a group of locals started working to change that, with the goal of making the old riverbed into a new attraction, something to help draw people downtown. Residents inspired by San Antonio’s River Walk worked with the conservancy district that controlled the river on an effort that took decades and resulted in the HARP, the Historic Arkansas Riverwalk of Pueblo.
