Water Supply Conditions as of Nov. 8, 2019
Fall weather returned to the Green River watershed mid-October, with a significant rainfall.
Conditions have been dry since around Oct. 26.
This summer, flows into the upper Green River hovered near the 3rd lowest on record since 1963. Above-normal rain in September improved our water supply and we finished the water year (Oct. 1 to Sept. 30) with close to average total rain.
