<br />' 2.0 SUMMARY OF HYDROLOGY MONITORING DATA <br />The Deserado Mine hydrology monitoring program was initiated during the first quarter of 1981 and <br />suxeeds the baseline hydrologic monitoring and inventory program that was initiated in 1978. The <br />' purpose of this section of this report is to: <br />• Describe the Deserado Mine hydrology monitoring program <br />' • Summarize the hydrology monitoring data collected from October 1, 1995 to September <br />30, 1996 <br />' • Compare the hydrology data collected during this reporting period with the data from the <br />baseline hydrology inventory <br />' 2.1 Descrlptlon of the Deserado Mlne Hydrologic Monltoring Program <br />An ongoing hydrologic monitoring program for the Deserado Mine was initiated during the first <br />' quarter of 1981. This program was designed based on the results of the hydrologic baseline studies <br />which were initiated in 1978. The program was implemented to tulfill the regulatory requirements <br />under the Federal Surface Mining Control and Reclamation Act (SMCRA) and the Colorado Surface <br />Coal Mining Reclamation Act. <br /> 2.1.1 Surface Water Monltoring Program <br /> The original surface water monitoring program consisted of monitoring surface water at the following <br /> nine (9) stations: <br />' SW1-1 (crest gage for flood events) SW31-1 (crest gage for flood events) <br /> SW11-1 (crest gage for flood events) SW33-1 (stock pond grab sample) <br /> SW12-1 (White River-grab sample) SW23-1 (nest gage for RP-1 discharge) <br />' SW11-2 (White River-grab sample) SW24-1 (nest gage Red Wash) <br /> SW6-1 (Stock pond-grab sample) <br />' The location of each of these stations is shown on Plate 1 in the pocket of this report. Stations <br />SWi-1, SW11-1, SW31-1, SW23-1, and SW24-1 are crest stage gages with single stage <br />' samplers and are designed to measure the crest of flow events and Dolled samples as the result <br />of those events. Stations SW6-1 and SW33-1 aze the locations of stock watering ponds where grab <br />' samples are to be collected. SW12-1 and SW11-2 are stations where grab samples from the White <br />River were collected. At stations SW6-1, SW33-1, SW12-1 and SW11-2 only water samples are <br />collected for analysis. Crest gage and water sample station SW23-1 is to be monitored only 'rf there <br />' is discharge from the sediment pond (RP-1) located below the refuse disposal area.
