INTRODUCTION

The Desert Research Institute (DRI) has conducted a
snow sampling program in the Tushar Mountain Range, Utah,
for the State of Utah Water Resources Division (UWRD). The
UWRD coordinates the winter cloud seeding program for the
State of Utah.

During the 1983 winter season the UWRD, with funding
obtained from the National Oceanic and Atmospheric Admini-
stration (NOAA), sponsored a cooperative field research
program designed to evaluate the State operational cloud
seeding program in the Tushar Mountain Range. The research
goals of this program were to obtain information relating
to: (1) the distribution, temporal and spatial, of super-
cooled water in the target area; (2) the trajectories of
cloud and precipitation particles in the target area; and
(3) t:he delivery of seeding materials into the target area.
Research goals one and two are under study by other univer-
sity and private sector groups.

In order to evaluate the program's third objective a
new Bnowpack sampling program was designed. This program
was designed to determine if silver iodide released from the
ground-based generator network was reaching the intended
target.
