Planned and Inadvertent Weather Modification/Weather Modification Association


The role of weather modification in the Colorado River Basin States process

Thomas J. Ryan, Metropolitan Water District of Southern California, Los Angeles, CA

In coordination with the Secretary of the Interior as part of a process to develop and implement improved management and operation of the Colorado River, the seven Colorado River Basin States have identified winter weather modification as an option to potentially increase snowpack and augment the flow of the Colorado River. Beginning in Water Year 2006, the Basin States in cooperation with local agencies have implemented actions for their mutual and overall system benefit. Three multi-state agreements have been executed to provide funds from the Lower Basin to extend or improve weather modification operations in the Upper Basin. Any water generated is considered water of the Colorado River System. The Basin States are currently preparing a long-term Action Plan to guide their future cooperative weather modification activities.
