have all been revised to correlate the old site (and map) name to the <br />new (Paradox) computer name. The new computer name will be used <br />throughout the following text. <br />After their review of Last year's Seneca II-W AHR, the CDMG made several <br />comments in a letter dated February 26, 2004. The CDMG's suggestions <br />regarding PHC projections have been incorporated into this AHR. <br />Meteorological Data <br />Precipitation data is collected from a Belfort Weighing Bucket Rain Gage <br />situated adjacent to Surface Water Site SW-S2W-FG1. Data for this year <br />may be found in Table 1. Total monthly precipitation data collected at <br />this site since Water Year 1990 are presented in Table 2. The Seneca II- <br />W precipitation gage measured 17.81 inches this year. This value is 0.10 <br />inches (1 $) above the 1990-2004 average of 17.71 inches. Temperature, <br />wind speed, and direction data from the Seneca II-W Meteorologic Station <br />are presented in Appendix B. <br />Data from the National Climatic Data Center's Hayden Station is used <br />here to evaluate the precipitation trend. For this year, 17,66 inches <br />of precipitation was measured, which is 0.32 inches (2$) above the 1971- <br />2000 average. November, December, February, April and September were <br />all above average. Snowpack runoff, as estimated by totaling November <br />through April precipitation values, was 9.45 inches, which was 0.70 <br />inches (8$) above the 1971-2000 average. <br />Snowpack runoff, estimated using the Seneca II-W precipitation gage, was <br />9.69 inches (November-April total), which is 0.60 inches (7$) above the <br />Seneca II-W 1990-2004 average, 9.09 inches. However, most of this snow <br />fell in November and December, which were above average months. Snowfall <br />totals in January through April were all below average. Especially <br />noteworthy is the March precipitation value, 0.57 inches, which is the <br />second lowest on record. It was also unusually warm that month, <br />resulting in an early snowpack runoff. These values are more relevant <br />2 <br />
