As Colorado River Negotiations Near a Critical Deadline, a New Way of Looking at Risk is Revealing Hard Choices Gwendolyn Miller Tue, 11/25/2025 - 11:45

A new article “As Colorado River Negotiations Near a Critical Deadline, a New Way of Looking at Risk is Revealing Hard Choices” highlights CADSWES and Reclamation’s new perspectives on river management.
The piece, recently published by the Water Education Foundation in Western Water, explores how a shift in understanding risk is driving new decisions for the future of the river.

The article takes readers through past and present efforts in modeling and managing the Colorado River, with a particular focus on insights gained from the �鶹��Ѱ��’s Center for Advanced Decision Support for Water and Environmental Systems (CADSWES). The author had the opportunity to interview key players on the Bureau of Reclamation’s modeling team, who are based at CADSWES, and the conversation also involved experts like Professors Edie Zagona and Joseph Kasprzyk, both of whom have contributed significantly to the development of tools used to evaluate river management strategies.

The article highlights the growing importance of these modeling tools, which are increasingly relied upon in this era of great uncertainty to explore a wide range of possible future conditions - including water usage and climate variability - to provide fresh perspectives on how to balance the competing needs of agricultural, urban and environmental stakeholders.

New framework and Web App for finding robust policies for the Colorado River Basin

New framework and Web App for finding robust policies for the Colorado River Basin Anonymous (not verified) Mon, 01/29/2024 - 16:11

A recent publication, “Interactive and Multimetric Robustness Tradeoffs in the Colorado River Basin” introduces a novel, interactive framework for stakeholders to identify policies robust to challenging climate futures.

Published in the ASCE Journal of Water Resources Planning and Management, December 30, 2023, the paper demonstrates the framework with a case study on reservoir operations in the Colorado River Basin using an open-access web tool created by authors Nathan Bonham, Joseph Kasprzyk, Edith Zagona, & Rebecca Smith.

This paper is one product of an enduring collaboration between CU’s Center for Advanced Decision Support for Water and Environmental Systems (CADSWES), and the Bureau of Reclamation to produce novel methods and tools for Decision Making Under Deep Uncertainty. The framework, case study, and web tool presented in this research catalyzed many aspects of another web tool Reclamation has since developed in partnership with Virga Labs and �鶹��Ѱ��Boulder, which is being used by stakeholders, Reclamation, and other governmental and nongovernmental agencies for early-stage exploration of operational strategies for the post-2026 NEPA process.

“We are excited about the positive impacts this research and ongoing efforts are having in the Colorado River Basin, and we are hopeful this research will be impactful far beyond the Basin’s boundaries,” says lead author and App inventor, Nathan Bonham.
