• <br />the Third White Sandstone in this area must be lower since 1986. <br />These declines are thought to be natural. <br />Water levels for the Johnson and Flume Gulch alluvial wells, <br />J1 and Coy, are presented in Fig~.rres 9-.35 and 9-36. The plot of J1 <br />water levels show fairly ste.ad.v values. Mine discharge into <br />Johnson Gitlr_h has maintained water levels in this a11~,~via1 svstem <br />during dry climatir_ conditions.
