Surface <br />water and ground water discussions are presented separately in the following sections. <br />2.2.1 Ground Water Monitoring Data Groundwater monitoring data consists of water <br />levels measurements. Tabulation of the data is included in Appendix C. Hydrographs for <br />the 19 stations (monitor holes) from which water level data were collected are included in <br />Appendix D. <br />2.2.1.1 Alluvial Water Level Data Water level data is still collected from the one <br />remaining original alluvial aquifer monitoring hole (Qal -5). Kenney Reservoir inundated five <br />other alluvial monitoring holes. A hydrograph of the water level data for Qal -5 is contained <br />in Appendix E. The location of Qal -5 is shown on Plate 1 in the pocket of this report.
