<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 />succeeds 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, 1996 to September <br />30, 1997 <br />• Compare the hydrology data collected during this reporting period with the data from the <br />' baseline hydrology inventory <br />2.1 Descrlptlon oT the Deserado Mlne Hydrologlc 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 fulfill the regulatory requirements <br />under tha Federal Surface Mining Control and Reclamation Act (SMCRA) and the Colorado Surface <br />' Coal Mining Reclamation Act. <br />' 2.1.1 Surface Water Mo Itoringprogram <br />The original surface water monitoring program consisted of monitoring surface water at the following <br />' nine (9) stations: <br />' SWi -1 (crest gage for flood events) -Discontinued as of 8/11/97 <br />SW11-1 (crest gage for flood events) -Discontinued as of 8/11/97 <br />SW12-1 (White River-grab sample) -Sampling discontinued due to inundation by Kenney Reservoir <br />' SW11-2 (White River-grab sample) -Sampling discontinued due to inundation by Kenney Reservoir <br />SW6-1 (Stock pond-grab sample) -Discontinued as of 8/11/97 <br />SW31-1 (crest gage for flood events) -Discontinued as of 8/1i/97 <br />' SW33-1 (stock pond grab sample) -Discontinued as of 8/11/97 <br />SW23-1 (crest gage for RP-1 discharge) -Discontinued as of 8/11/97 <br />' SW24-1 (crest gage Red Wash) -Discontinued as of 8/11/97 <br />However, during the 1996-1997 water year only seven (7) surface monitoring stations were required <br />to be monitored: SWi-1, SW6-1, SW11-1, SW23-1, SW24-1, SW31-1 and SW33-1. <br /> <br /> 2 <br />' <br />1 <br />
