<br />Since Emery WCD were participants in the project, it was decided that the APES <br />prototype would seed the mountains west of Joes Valley Reservoir (on Utah's <br />Wasatch Plateau), weD's principal water storage facility. This area is also <br />close to the Utah/NOAA research field site. On August 2, 1993, Arlin Super, <br />Jack McPartland, (D-3720) and Erick Faatz (UDWR) visited the Wasatch Plateau. <br />They fixed the sites for the three dispensers (see Table 1 and Figure 1). All <br />three sites listed below are well exposed to the prevailing winds during <br /> <br />storms; that is from south-southeast through northwest. <br /> <br />Table 1 <br /> <br />Locations for APES Dispensers <br /> <br />Name Latitude Longitude Elevation <br /> (deg-min) (deg-min) (feet-msl) <br />Bald Mountain 39-32.0 111-19.2 8770 <br />Freds Flat 39-21.0 111-28.7 9040 <br />Hell Hole Ridge 39-22.4 111-28.1 9135 <br /> <br />It was determined that the base unit would be located at Freds Flat because it <br /> <br />was centrally located and had commercial power nearby. The commercial power <br /> <br />will be used for some of the meteorological sensors, in particular to deice <br /> <br />the wind instruments. Should the prototype testing be successful, it is <br />believed that future systems would not need commercial power. For example, <br />the Rosemount icing rate meter could be powered by a battery continuously <br />recharged by a propane-powered thermoelectric generator. <br /> <br />5 <br />
