July was characterized by warm and wet conditions. The first half of August has been cool, particularly east of the Continental Divide with near normal precipitation. Reservoir storage remains high, and municipal water providers have no immediate concerns with levels of supply and demand in their systems.
Reservoir storage statewide remains high at 116% of average. After receiving 130% percent of statewide average precipitation in July at SNOTEL stations, August precipitation through August 16 was 110% of average in the mountain areas. Much of eastern Colorado was exceptionally wet in early August. Reference evapotranspiration (ET), an indicator of how much water that can be consumed by crops, has been below normal for the first half of August.
Colorado water and climate professionals are bidding a sad farewell to our longtime State Climatologist, Nolan Doesken. Nolan is retiring after 40 years of service to Colorado. In his presentation to the August Water Availability Task Force meeting, Nolan provided some long-term graphs relevant to Colorado climate and water supply.
