As a headwaters state, Colorado has many interstate compacts that set rules for how the state must share the rivers that originate within its borders with downstream states. On several of these rivers, water users have had to modify their water use to meet compact requirements. That day may be coming for the Colorado River. A new report explores what Colorado River water users can learn from experiences with compact administration on other rivers.
The new report, “Lessons Learned from Colorado Experiences with Interstate Compact Administration,” utilizes interviews with water users and experts who experienced compact compliance measures in the Arkansas, Rio Grande and Republican River Basins to distill lessons that may be useful for Colorado Basin water users.
Interviewees warned against relying on courts to rule in Colorado’s favor in compact cases or on optimistic estimates of water availability. They also described how communities have developed their own, proactive measures to promote compact compliance and address other water supply challenges in ways that have fewer negative impacts than externally imposed mandates. Necessary conditions for doing so include an ability to work well together, precise water-use measurement and initiating action well in advance of a court order. On a more technical front, interviewees emphasized how accurate measurement of all water use was necessary for enhanced water management, as well as making the Colorado’s case for its own water use in discussions with other states.
This study was conducted by Kelsea MacIlroy, co-written by Hannah Holm and funded by The Nature Conservancy. MacIlroy is a PhD candidate in sociology from Colorado State University and the principal of MacIlroy Research and Consulting, LLC. Hannah Holm directs the Hutchins Water Center at Colorado Mesa University.
The report was presented at the Colorado Water Congress Summer Conference in Steamboat Springs on August 24, 2021, and will be presented at the September Colorado Water Conservation Board meeting.
“Across Colorado and the West, communities are experiencing greater frequency and extent of drought leading to increased variability in streamflows. As water managers grapple with the consequences of changing water supplies, there is great value in looking toward neighboring communities for lessons learned,” Heather Dutton, manager of the San Luis Valley Water Conservation District and the Rio Grande Basin’s representative to the Colorado Water Conservation Board said. “The report detailing “Lessons Learned from Colorado Experiences with Interstate Compact Administration” relies on voices of water users and administrators to detail personal and regional experiences including what has gone well and where they would do things differently if given the chance. While the focus of the report is on compact administration, the lessons learned touch on broader water management topics and highlight how communities are better off when stakeholders are working toward a common goal. Therefore, I feel this report is a must read for all Coloradoans that care about our collective water future.”
Alex Funk, agriculture and rural resiliency policy specialist for the Interstate, Federal, and Water Information Section at the Colorado Water Conservation Board also commented on the recent report.
“The stories shared in this report highlight the value of proactive dialogue and actions on water management challenges ranging from climate change to compact compliance.,” Funk said. “Collaborative, proactive actions and solutions give local communities and water users more agency and opportunities to adapt to changing conditions in ways that provide long-term benefits for all water users.”
On the question of water measurement, John McClow, general counsel for the Upper Gunnison River Water Conservancy District said, “A valuable takeaway from the report is recognizing the importance of accurate measurement. That is a good lesson for Colorado River water users as the State Engineer commences measurement rule making.”
