The original design assumed that liquid water would form along the crest of the <br />Sierra. allowing initial growth orthe crystals. The liquid cloud would then begin to dissipate <br />over the valley but reform along the second ridge. It was assumed that along and just over <br />the second ridge, most of the seeding effects would he observed. Thus, most of the <br />precipitation gauges were sited in this area. <br /> <br />The LOHEP precipitation gauge network cunsisted afoine project-installed gouges plus four <br />existing DWH (O<'partmcnt of Water He-sources) gauges. Table 2.3 is n list of the gauges <br />installed specifically for the LOREP, as well as the DWR existing gauges. Figure 2.6 shows <br /> <br />10 <br />
