The water resources of the Snake River Basin (both surface and ground) are being stressed by drought, population growth , and increasing demands by agriculture, cities, and recreational activities.  Therefore, the High Country Resource Conservation and Development Council conducted a winter cloud seeding program to augment snow packs.  The target areas were Upper Snake River Basin and those watersheds draining into Water Basin 31.  The program ran from November 1, 2007 to April 1, 2008 and was contracted out to Clark County and Let it Snow Inc.

  Results of Snake River Basin Cloud Seeding 08-09:

  IDWR perspective on weather modification said there is conceptually

  defensible and documented success.  It is difficult to quantify  the

  effectiveness because so many variables exist.  Success of the program

  relies on the quality of the program as well as it's operators.  Current SNOTEL 

  data shows reported areas have experienced more than 100 percent

  precipitation during this winter season. 

 

  The North American Weather Consultants, Inc.  prepared results from regression

  equations developed for the operational uppers snake river cloud seeding

  program. The results showed the northern region ranged from 3-4%

  additional snow pack. While the eastern region ranged from 6- 9% of additional 

  water content.

  Future Goals for the Snake River Basin Cloud Seeding:

  • $150,000 to be raised for next year's cloud seeding project
  • Continue partnership with Idaho Power
  • Hire intern to help with fundraising
  • more SNOTEL research sites

  What is cloud seeding?

Cloud seeding is a proven tool to increase precipitation

and numerous evaluations have indicated that cloud seeding , when properly applied, can produce precipitation increases up to 10% or greater.  Cloud seeding is a form of weather modification. It can be used to disperse fog, suppress hail, or control winds, but is most often used to increase precipitation. It introduces other particles into a cloud to serve as cloud condensation nuclei and aid in the formation of precipitation.
