to the new (Paradox) computer name. The new computer name will be used <br />throughout the following text. <br />Meteorological Data <br />Precipitation data was obtained at the Seneca II Mine using a Belfort <br />Weighing Bucket Rain Gage. Daily precipitation data for this year are <br />presented in Table 1. Total monthly precipitation data collected since <br />1981 are presented in Table 2. Where indicated, data from the U.S. <br />Weather Service - Hayden Station were used. Temperature, wind speed and <br />direction data are presented in Appendix B of the Seneca II-W AHR. The <br />Seneca II-W Mine Meteorological Station located approximately seven <br />miles southwest of the Seneca II Mine. Climatic conditions are similar <br />between the two mines. <br />Data from the National Climatic Data Center's Hayden Station is used <br />here to evaluate the precipitation trend. For this year, 19.68 inches <br />of precipitation was measured, which is 2.34 inches (13%) above the <br />1971-2000 average. The months of October, December, January, February, <br />March, May and September were above average. Snowpack runoff, as <br />estimated by totaling November through March precipitation values, was <br />10.98 inches, which was 3.80 inches (53%) above the 1971-2000 average. <br />The Seneca II precipitation gage measured 15.97 inches this year. This <br />value is 2.29 inches (13%) below the 1981-2008 average. Snowpack runoff, <br />estimated using the Seneca II precipitation gage, was 9.34 inches <br />(November-March total), which is 1.98 inches (23%) above the Seneca II <br />1981-2008 average. <br />Ground Water <br />Water Levels. Water level data are presented in Appendix B. Water <br />level reports for data collected since 2003 are presented immediately <br />after the water level hydrograph of all historic data for each <br />respective well. By presenting all historic data, trends related to <br />seasonal and annual variability and possible mining related impacts are <br />2
