Streamflow Tracker

September 15th, 2022: The Streamflow Tracker table has been updated for August 2022 (scroll down to see April – July 2022). This table shows recent and Water Year streamflow conditions across 14 of the largest basins within Colorado. The Tracker shows the following data:

  • Observed value (units: thousands of acre-feet)
  • Normal or Average value (units: thousands of acre-feet)
  • Percentage of Normal Value
  • The Observed value’s percentile given the location’s period of record. Note all the sites below were intentionally chosen due to their long duration, giving the percentile more meaning.
