<br />years of recovery were simulated to the end of year 2024 (Figures l0a and <br />lOb). <br />The maximum depletion in all affected streams equals 129e (or 13.7 ac- <br />• <br />ft/yr) of the total pumpage for both wells and occurs at the end of <br />mining, simulation year 15, when both wells have been pumping (Figures 9a <br />and 9b). The highest individual stream depletion during this time occurs <br />in Grassy Creek and is projected to be 6.3% of the total pumpage or 7.09 <br />ac-ft/yr (Table 3). Most of the stream depletions are caused by long-term <br />pumpage from the Yoast well. This is due to the location of the Yoast <br />well which is closely surrounded on three sides by the Trout Creek <br />outcrop/recharge area and, consequently, to areas where streams cross the <br />Trout Creek outcrop. Most of the ground water withdrawn is derived from <br />aquifer storage. <br />Drawdown <br />Maximum drawdown of about 216 feet occurs in the Yoast well when both <br />n <br />wells are pumping at the end of mining, simulation year 15 (Figures 8a and <br />8b). When only the Yoast well is pumped, the maximum drawdown is 215 feet <br />suggesting that the influence of the Seneca IIW well at the Yoast well <br />when both wells are active is only 1 foot. Maximum drawdown for the IIW <br />well at the end of simulation year 15 is 172 feet when modeled both alone <br />(Figures 4a and b) or together with the Yoast well (Figures Sa and 8b). <br />Thus, the wells are not expected to interfere with each other. <br />8333003.004 <br />7 <br />GeoTrans, inc. <br />
