Monitoring Sites; and the Table of Contents of Appendices C through E have all been revised to correlate the old site (and map) name to the new (Paradox) computer name. The new computer name will be used throughout the following text. Meteorological Data Precipitation data is collected from a Belfort Weighing Bucket Rain Gage situated adjacent to Surface Water Site SW-S2W-FG1. Data for this year may be found in Table 1. Total monthly precipitation data collected at this site since Water Year 1990 are presented in Table 2. The Seneca II- W precipitation gage measured 18.53 inches this year. This value is 0.99 inches (6%) above the 1990-2008 average of 17.84 inches. The months of October, December, January, February, March and may were above average. Temperature, wind speed, and direction data from the Seneca II-W Meteorologic Station are presented in Appendix B. Data from NOAA's Hayden Station are also provided in Appendix A.

Snowpack runoff, estimated using the Seneca II-W precipitation gage, was 9.79 inches (November-March total), which is 2.75 inches (39%) above the Seneca II-W 1990-2008 average, 7.04 inches. Ground Water Water Levels. Water levels for all wells that are in the current monitoring program are presented in Appendix C. Hydrographs of all historic data for each well are presented prior to the water level reports (for all data since 2000) for each respective well in the same 11 • • 2
