The values for the wet year may be an overestimate in some winters if seeding suspension criteria <br />suspends operations. <br />Table 4.3 does not take into account the varying opportunity across year type to conduct cloud seeding; <br />namely, the possibly differing cloud numbers and level of favorable seeding circumstances in available <br />4 <br />Figure 4.1. - Sample seeding device placement in the Headwaters Region for 240 degree winds <br />(adapted from Holroyd's unpublished Reclamation memorandum, 2000). <br />clouds. The table values assume uniform opportunity across normal, dry and wet years. The design <br />phase of the project will look into this issue. It may be that dry years offer more inefficient natural clouds <br />than normal and wet years, thus presenting more treatment opportunities (or fewer opportunities). <br />26 <br />
