The National Oceanic and Atmospheric Administration (NOAA) National Integrated Drought Information System (NIDIS) reports that 100 percent of the county is experiencing drought. Although June 2022 was the second wettest June in 128 years, with 2.48 more inches of precipitation than normal, 2022 to date is the 33rd driest year in the last 128 years, with 2.84 inches of precipitation less than normal, according to the NIDIS.

The NIDIS places the entire county in a severe drought, which the
website notes may cause farmers to reduce planting, producers to sell cattle and the wildfire season to be extended, among other impacts. The NIDIS also notes that a severe drought is associated with low surface water levels and reduced river flows.

The NIDIS provides an evaporative demand (EDDI) forecast…The forecast for the area indicates that in the next two weeks, the majority of Archuleta County will be experiencing a mix of severe wet and extreme wet conditions while the four-week forecast shows the county will be experiencing a mix of severe wet and moderate wet conditions.
