Water Year 2019 (WY 2019) included a wet spring and a dry late summer and early fall. Precipitation patterns are a factor in CCR’s water quality.
Precipitation measured at the KAPA site was much lower than average during the 2019 Water Year. The historical data from the National Ocean and Atmospheric Administration (NOAA) at the Centennial Airport Station (KAPA), received 79% of the average precipitation based on the previous 12 years of data.
However, the watershed as a whole appears to have received above average precipitation, based on the 30 year (1981-2010) PRISM average precipitation data generated by NOAA/National Weather Service.
