• Title: Weather Modification Reporting Program - 1973-1978
• Date: 6/1/1979
• Weather Modification - Doc Type: Report

"Snowpack accumulation will be monitored. Recent evaluations of
snowpack and snowmelt runoff in the springtime indicate that minor
flooding and stream flow problems can exist when snowpacks reach 150
percent of normal. More substantial flooding problems can be antic-
ipated when snowpacks in excess of 170 percent of normal me1toff in
the springtime. Since this program is designed for reasonable levels
of snowpack enhancement for an outlook of an adequately abundant
summertime water supply for storage and use, the contractor proposes
to suspend seeding operations in any major portion of a seeding area
when the average snowpack in that seeding are monitored at several
representative sites exceeds and remains about 135 percent of normal.
Seeding operations would continue in the remaining mountain regions
under normal operational procedures. This comparative normal for
these representative snow observation sites will be the latest fifteen-
year average as published by the Soil Conservation Service.

"The contractor further proposes to establish an advisory committee
of representatives from each major watershed involved in this program
and to coordinate with the representatives the aspects of the program
operations which have a bearing on and are of concern to the local in-
terests. This coordination could provide information for hazard and
dis-benefit evaluations and should produce substantial goodwill and
help to foster local acceptance of the weather modification program.
The Local Advisory Committee concept will also provide a modicum of
local control of the seeding operations, easing fears and uncertainties
throughout the duration of the program~"
