<br />was compounded by the fact that two of the three proj-
<br />ect years were drought years, limiting seeding periods,
<br />while the other year had record snowfall, suspending
<br />seeding operations. This severely restricted the number
<br />of randomized cases available for statistical analysis.
<br />Again, it would seem imperative that detailed transport
<br />and dispersion studies be performed prior to the onset
<br />of any long-term snowfall enhancement program in or-
<br />der to confirm that successful targeting is possible for
<br />a majority of storm periods when liquid water is ob-
<br />served.

<br />Acknowledgments. The LOREP was managed by the
<br />California Department of Water Resources and funded
<br />by the State Water Project. Technical direction was
<br />provided by the Bureau of Reclamation. A special
<br />thanks goes to the Water Resources staff at Beck-
<br />wourth, California, for their monumental effort in help-
<br />ing to conduct the 1993 field program. In addition, Mr.
<br />Jack McPartland of the Bureau and Mr. Bill Haas of
<br />North American Weather Consultants provided ex-
<br />traordinary efforts in collecting a portion of the data
<br />used in this study. Thanks also to the pilots and support
<br />crew of the NOAA research aircraft for their skill and
<br />professional attitude in conduting a very difficult flight
<br />profile in winter storms over complex terrain.
