Western States Have Ideas for Water Use

Laramie, Wy – The Colorado River states are trying to think outside the box when it comes to stretching a supply already stressed by population growth and ongoing drought.
Wyoming and six other states have sent a letter to Interior Secretary Gale Norton - outlining proposals for dealing with or averting shortages.
The focus is on three areas, including augmenting the river's flow.
Among the possible sources of new water, the easiest and cheapest to try is cloud seeding. That's where silver iodide, or dry ice, particles are spewed into a storm to induce more rain or snow.
The technology is more than 60 years old and scientists say it works, as long there are clouds and moisture to tap.
