According to the Bureau of Reclamation, water supplies for irrigation remain tight, and for junior districts, not much improvement. The latest August report for what's called the Yakima Basin, which also includes SE WA and Tri-Cities, remains a little grim. On Aug. 1, the amount of water in the snowpack, known as snow water equivalent, was 0% of average." Senior water rights holders, such as Columbia Irrigation in Tri-Cities will still get 100 percent of their allocated water. The Pasco Irrigation District, serving the city, does not qualify, they pull their water from the Columbia.
