• The following is a listing of the average monthly flows in these creeks during the most critical irrigation months, July-October: SWGS-O1 Water Year October July August September 1987 - 2.70 2.31 1.27 1988 1.90 1.71 1.06 1.68 1989 1.80 0.88 0.80 <0.56 1990 0.71 <0.73 <0.72 <0.70 1991 <0.92 <1.24 <0.56 <0.60 SWGS-02 Water Year October July August September 1987 0.74 1.02 0.57 0.48 1988 0.53 0.44 0.32 0.39 1989 0.38 <0.26 <0.26 <0.26 1990 <0.26 <0.26 <0.26 <0.26 1991 - <0.26 <0.26 <0.26 SWGS-03 Water Year October July August September 1987 - 0.75 0.34 0.20 1988 0.40 0.92 0.31 0.37 • 1989 <0.16 <0.26 <0.17 <0.15 1990 <0.16 <0.15 <0.15 <0.15 1991 <0.24 <0.50 <0.29 <0.21 - indicates months when insufficient information was available. Powderhorn continued to operate on an extension of our old CDPS discharge permit. A renewal application was submitted to the Department of Health in January, 1990, but a new permit has not been granted. As usual, there were no discharges from the sediment ponds due to normal site runoff. Pond No. 6 did discharge in September, 1991, as a result of flooding in Coal Canyon which overflowed into the pond. Other than this emergency discharge, no discharge was reported for outfalls 005 through 014. Outfall 3 is an abandoned discharge point for dewatering the Old Cameo mine and had no reported discharge for the year. outfall 002 is a discharge point for dewatering the Roadside Mine. The permit renewal application proposes moving the location of this outfall to the Northwest Intake portal. Water formerly pumped from this point has been filling the abandoned portions of the Roadside Mine since last pumped in 1989. The water level is projected to reach the Northwest Intake portal . during late 1992 or early 1993, at which time discharge from outfall 002 will resume.
