Therefore, <br />all recorded monitoring events are considered operational. <br />The lower monitoring point for the Fire Mountain Canal is located at a point just south of its crossing under old State Hwy 133. <br />Flow data is received from Fire Mountain Canal records (Merritt Dennison 970-527-4385). <br />There is no baseline collection possible for points initiated after the influence of mining. <br />Figure No. 112
