The Colorado River Research Group (CRRG) was formed in 2014 to bring scientific insights to Colorado River system management, inspired in part by the salient role played by the Wentworth Group of Concerned Scientists in the Murray-Darling Basin—a similar, drought-stricken region in Australia. It was established as an independent, knowledgeable voice insulated from political constraints, sectoral alliances, and other pressures that might impede the full consideration of relevant ideas and viewpoints. Originally, the CRRG was launched with ten members, all academics with long, well-established involvement in Colorado River scholarship. In 2021 the group was expanded to 14 active members, while four original CRRG members transitioned to emeritus status. CRRG members serve as individuals, rather than as representatives of their universities or other organizations. The administrative home of the CRRG is the Getches-Wilkinson Center at the University of Colorado.
