In order to increase the water resources of the state of Utah in the U.S.,?
In order to increase the water resources of the state of Utah in the U.S., a new cloud seeding programme has been undertaken to increase the amount of snowfall in the mountain areas.
Cloud seeding is done by planes equipped with silver iodised flares. As the flares burn when the aircraft passes through clouds, millions of crystals are released. Moisture in the clouds collects on the crystals until they are heavy enough to fall to earth as snow.
In the project's main target area, snowfall from some storms has been increased by over one-hundred per cent.
SYNOPSIS: Flying through the clouds over northern Utah, this aircraft is carrying four racks of silver iodised flares, which spread millions of small crystals as they burn. Moisture collects on the crystal until they are heavy enough to fall to earth -- as snow. The project is part of the Bureau of Reclamation's Project Skywater, designed to increase the water resources of Utah.
In the Water Resources Laboratory in Salt Lake City, forty-six remote controlled monitoring stations continually report snow depth and water content by radio. These mountain-top stations are spread throughout the state. In the project's main target area, snowfall from some storms has been increased by over one-hundred per cent, while overall snowfall in northern Utah has increased by thirty per cent.
There are some who question the environmental effects of artificially increasing the amount of snowfall. Ranchers and farmers in neighbouring states could claim that Utah is stealing their water, as the cloud seeding process would force the snow to fall before it reached their land.
