Therefore, <br />all recorded monitoring events are considered operational. <br />The upper monitoring point for the Fire Mountain Canal is located where the ditch crosses Hubbard Creek. <br />Flow data is received from Fire Mountain Canal records (Trey Dennison 970-527-5166 or cell 970-589-2857). <br />* Data not provided <br />**Average flow values from last five years <br />There is no baseline collection possible for points initiated after the influence of mining. <br />Figure 73 <br />
