• 2001 Annual Hydrologic Report Page 2 <br />graphically on data page SG-32. As usual, the flow in these Creeks is largely controlled <br />by the City of Palisade, depending upon their need for domestic water. Also, irrigation <br />water is diverted from the creeks by private water right holders at various locations. Table <br />S01-1 was prepared to show the average monthly flows during the primary irrigation <br />season when low flow in the creeks is critical, Gaps in information are due to problems <br />with the recorder or flows below the minimum recording level of the recorder. Minimum <br />recording levels of the flumes are listed at the bottom of Table S01-1. <br />Monitoring on Coal Creek and Jerry Creek was started in 1995. The crest stage gages <br />installed in Coal Canyon drainage and Jerry Creek in 1996 were destroyed by a storm in <br />the summer of 1998. Discussions with DMG have indicated there is no need to monitor <br />the upstream locations SWGS 07 and 09. The creeks will only be monitored at the lower <br />monitoring points. The ephemeral flow in Coal Creek is measured at culverts located <br />between the two refuse disposal areas, SWGS 06. These culverts provide a stable cross <br />section and are accessible throughout the year. The intermittent flow in Jerry Creek is <br />measured at the culvert near the Highline Canal, SWGS 08. Beginning July 1999, <br />instantaneous flows are to be monitored quarterly. Data taken during the Year are listed <br />on data pages SR-2 for Coal Canyon and SS-2 for Jerry Creek. <br />• There were three seeps included in the hydrologic monitoring in 1995. The location of the <br />seeps are shown on the Hydrologic Monitoring Map. They are located adjacent to Coal <br />Canyon drainage and Jerry Creek. They are primarily evident by the white staining on the <br />hillsides from evaporation of the seeps. None of them flow to the creek channel but <br />generally evaporate within a couple of hundred feet of the source. On April 28, 2001 the <br />springs were monitored. S-95-1 and S-95-2 were damp; S-95-3 was damp to dry and S-95- <br />4 was dry. The monitoring results to date are shown on data page ST-1. <br />There was no discharge from CDPS discharge points 004 thru 015 during the Year. These <br />outfalls cover sediment pond discharges. Discharge point 015 is permitted to allow <br />pumping water from the south end of the Roadside South Portal out the 2 West portals. <br />Piping to this point will not be installed. Discharge point 016 is permitted for gravity <br />discharge from the northwest intake pool. It will replace outfalls 001 and 002. <br />Discharge point 001 was primarily used as an overflow to a mine water system for the <br />preparation plant during mine operations. During March and April 2000, a discharge pipe <br />was installed from the No.2 South Mains sump to outfall 001. The routing of this 4-inch <br />• diameter pipe is presented on permit Figure 14-6. The capacity of this discharge pipe is <br />
