<br />fall as rain, not snow., Thus, the increased precipitation <br />would be used to augment winter flow into Roosevelt Reservoir. <br /> <br />Aerial seeding with silver iodide along Victor Airway 94 <br />produced good increases in the Salt River drainage. Similar <br />simulations with dry ice shifted the effects upwind into the <br />Gila River drainage. With light wind cases, dry ice seeding <br />near Cibecue (Victor Airway 190) resulted in increases on <br />the Mogollon Rim. Aerial seeding at other locations, such <br />as over Superior or Miami, would not be practical due to military <br />flight operations (see Section 3.1.3 and Figure 3.2). <br /> <br />3.2.3 Modeling Results for the Upper Salt River (BALDY) <br />Results of seeding simulations for the upper Salt River drainage <br />are listed in Table 3.3. Ground-based seeding was simulated <br />at Klondyke, atop a ridge 20 km northeast of Klondyke, at <br />Bylas (in the Gila River Valley), and 80 km northeast of Klondyke <br />(atop a rise separating the Gila and Black River drainages). <br />With stable flow, the simulated seeding plume from Klondyke <br />never reached the seeding target area due to time limitations <br />within the model. No such limitations exist in the wreal <br />world". However, targeting problems do exist, and they could <br />be substantial considering the distances involved. The other <br />simulations with stable flow resulted in slight increases <br />in the Baldy Peak area, as long as the ammonium perchlorate <br />additive was used. No increases were simulated without it. <br />Ground-based seeding under convective conditions produced <br />better results from all four seeding locations, although seeding <br />80 k~ northeast of Klondyke tended to produce most of the <br />effects downwind of Baldy Peak. <br /> <br />Aerial seeding with silver iodide near Klondyke (along <br />Victor Airway 94) produced good increases in the Salt River <br /> <br />3-21 <br /> <br />-~ <br />
