Media Contact: Pete Lucero, 916-978-5100

For Release: November 12, 2010

The Bureau of Reclamation has released for public review a Draft Environmental Assessment for award of a grant for the Walker River Basin Cloud Seeding Project. The project is intended to increase precipitation in the Walker River Basin through cloud seeding to enhance snowpack and streamflow. Cloud seeding activities would occur in Lyon, Douglas and Mineral counties in Nevada and in Mono and Tuolumne counties in California. Reclamation's Desert Terminal Lakes Program would grant more than $1.3 million to the Desert Research Institute (DRI) to extend the cloud seeding program for a five-year period, using five ground-based seeding generators and supplemental airborne cloud seeding each winter. The DRI would use a modeling system to estimate changes in Walker River flows as a result of the cloud seeding.

The Draft Environmental Assessment (EA) was prepared in accordance with the National Environmental Policy Act and is available online at If you encounter problems accessing the document online, please call 916-978-5100 or e-mail
