From The Pueblo Chieftain (Chris Woodka):
Brown and Caldwell engineers, consultants for the project, are conducting interviews and using surveys to determine the feasibility of developing a support system for the Arkansas River Basin. The project is coordinated by the Colorado Water Conservation Board.
The Rio Grande and Colorado River basins already have these models in place, and they have been used to help shape state and federal water policy. A decision support system is being completed for the South Platte River Basin as well. Although the process of developing the models began more than 20 years ago, the Arkansas River project was delayed because of the ongoing Kansas v. Colorado case in the U.S. Supreme Court. The case was settled last year. The model would provide a common baseline for historic water use that could be applied to future proposals, explained Lindsay Griffith, project manager for Brown and Caldwell.
