@USBR completes review of #ColoradoRiver operations for #LakePowell and #LakeMead #COriver #aridification #CRWUA2020

Here’s the release from Reclamation (Patti Aaron and Linda Friar):

The Bureau of Reclamation today released a report intended to bring partners, stakeholders and the public to a common understanding of the effectiveness of the 2007 Colorado River Interim Guidelines for Lower Basin Shortages and Coordinated Operations for Lake Powell and Lake Mead. The technical report documents conservation efforts and operations on the Colorado River since 2007 and provides an essential reference to inform future operations.

“The report presents a thorough review of operations and highlights that we have experienced historic collaboration among states, tribes, water users, non-governmental organizations and the international community in addressing issues affecting one of America’s most important rivers,” said Commissioner Brenda Burman. “Forty million people across seven states and Mexico depend on the Colorado River for life and livelihood, so it’s critical that our actions protect this resource now and into the future. Today’s report highlights both the historic steps taken in the basin, as well as the need for continued progress to meet the growing challenges in the years ahead.”

The report concluded:

– The 2007 Interim Guidelines were largely effective as measured against both their stated purpose and common themes as provided in the 2007 Record of Decision.

– Increasing severity of the drought necessitated additional action to reduce the risk of reaching critically low elevations in Lakes Powell and Mead.

Experience over the past 12 years provides important considerations:

– enhanced flexibilities and transparency for water users

– expanded participation in conservation and Basin-wide programs

– increased consideration of the linkage that occurs through coordinated reservoir operations, particularly with respect to the inherent uncertainties in model projections used to set operating conditions

– demonstrated need for more robust measures to protect reservoir levels

The report and additional information is posted at https://www.usbr.gov/ColoradoRiverBasin/.
