Bowie Mine, Terror Creek Reservoir Area PROJECT NO. 27-218 <br />Pre-Subsidence Inspection <br />Area 1 is located at the northern end of the reservoir and includes the inflow <br />ditch, three existing cabins, a Parshall flume at the inlet to the reservoir, as well <br />as the saddle dam and spillway area. Construction at the spillway area and along <br />the north side of the dam had occurred recently. Re-grading of some areas was <br />evident and the vegetation had not yet returned. It appeared that the grade of the <br />stream bed in the inflow ditch may have been steepened to allow installation or <br />repair of the flume. The channel sides of the creek are steep and may be subject <br />to erosion until they stabilize themselves by flattening and vegetating. Very steep <br />slopes exist along the spillway outflow some 200 feet to the north of the dam. <br />The slopes are around 30 feet in height and appear to be over steepened and <br />unstable in their current conditions. <br />' w. <br /> <br />4F <br />1 <br />*,./. <br />Y" <br />Photo #1, North saddle dam looking east from west abutment
