This is the final report on the preparation of a design program to apply results from experimental programs for augmenting orographic precipitation to a Pilot Project that would have the goal of providing "...sound scientific and engineering evaluation of precipitation creases over a large area by operational-type application of cloud seeding techniques...", (Kahan, 1969). The report describes: (1) the purpose of the project; (2) the scientific and technological basis; (3) the design constraints; and, (4) the details of the design. The design itself includes descriptions of: (1) the experimental hypothesis; (2) the site selection; (3) the experimental procedures (randomization. etc.); (4) the data collection requirements; (5) the operations procedures; and, (6) the evaluation techniques to be employed.
