Today, KWUA received a letter from the Bureau of Reclamation, supplementing its April 9, 2025, communication regarding water availability from Upper Klamath Lake and the Klamath River. While Reclamation states in its letter that forecasted hydrology on June 1st was not as favorable as previous forecasts, it maintains that Project supply “for the 2025 irrigation season continues to be expected to meet anticipated Project demands as based on current hydrology and historical use patterns. Read the entire letter below.
Dear Ms. Nielson
This letter supplements the Bureau of Reclamation’s (Reclamation) letter dated April 9,2025 regarding availability of Klamath Project (Project) water from UKL and the Klamath River.
The forecasted hydrology on I June, 2025 was not as favorable as previous forecasts. Project Supply for the 2025 inigation season continues to be expected to meet anticipated Project demands as based on curren hydrology and historical use pattems. The Project Supply determinations for inigation have been determined to comply with the relevant Biological Opinions for the Klamath Project. Project supply continues to be made available at previous levels. This determination is based on results from the Keno Release Model and a predicted availability from a combination of other Project sources. Ongoing monitoring of hydrology and diversions will continue with updates as new data otherwise becomes available throughout the season. Reclamation will continue to collaborate with contractors in light of updated supply calculations and also consider the need for any necessary operational changes to account for deviations from expected demand.
For contractors that divert Project water directly from Upper Klamath Lake or the Klamath River, to the extent provided by contract, Reclamation personnel will be reaching out to contractors frequently during the season to verify measurement of diversions.
This information will be updated as conditions warrant.
Please direct any questions or comments regarding this letter to Heather Casillas at hcasillas@usbr.gov.
