The Central Arizona Project is pulling financial support for cloud-seeding efforts meant to boost snowfall in the Colorado River headwaters, the latest casualty of a widening Colorado River water war. CAP had provided some $447,000 to the program in Wyoming, Colorado and Utah last year, and would have provided up to $525,000 in the coming year, rising gradually to $750,000 by 2036. Instead, the CAP board’s majority rejected renewal at a time when states are fighting over the river and there’s no clear documentation of where the water ends up. The board on Nov. 5 decided not to renew a 10-year agreement that in the past used funds from water agencies in all seven Colorado River states to spray silver iodide molecules into advancing storms in the Rocky Mountains to squeeze more precipitation. The collaboration is meant to boost the flows that all seven states rely upon, though some of the detractors questioned whether any of the resulting water actually reaches Arizona.
