3 Grou nd ater is an important soure of ater for. The Northern Distrit of the Department of Water Resoures has olleted data on ground ater levels from more than 7 ells in the ounty. Foreord This report summaries ground ater leval data olleted by the Department through April 992. The report presents loations of ells, information related to the monitoring program, and hydrographs depiting ground ater levels over time. This information ill provide the basis for a better understanding of ground ater leval trends in Butte County. Understanding these trends ill aid in management of this important resoure.

9 Introdution Sine the 94s, DWR has measured ground ater Javels in more than 7 ells. Currently, 5 ells are monitored semiannuaijy. ln addition, DWR measures 6 ells on a monthly basis. This report is a ompilation of information related to the monitoring program in and inludes ground ater hydrographs for the monitored ells.

10 State Weil Numbering System Eah eil in the monitoring program is assigned an offiial State Weil Number. DWR has sole responsibility for assigning State Weil Numbers to ater ells in California, and eah number uniquely identifies a eil based on its loation. Eah State Weil Number inludes tonship, range and setion number, and eah setion is further subdivided into sixteen 4-are trats, hih are assigned a letter designation as shan belo. Within eah 4-are trat, ells are numbered sequentially in the arder they are inventoried. The final letter of the identifiation signifies the base line and meridian to hih the eil loation refers. ln, ali ells are referened to the Mount Diablo base line and meridian.

11 Measurement Frequeny and Period of Reord Table shos the period of reord and frequeny of measurement for ells monitored historially by the Ground Water Setion of the Northern Distrit. The ells urrently measured are labeled as ACTIVE. Most ells are measured semiannually: one in spring, usually during Marh, and one in fall, during Otober. Dates of the measurements are timed to obtain the approximate highest stati ater level in the spring and approximate loest stati ater level in the fall. Currently, six ells are measured monthly to provide a reord of ho levels hange throughout the year. Over ti me, the measurement frequeny for many ells in the monitoring program has alternated beteen semiannually and monthly. The Measurement Frequeny'' olumn in Table reflets only the most reent measurement frequeny for the ells.

13 Weil Loations Loations of monitoring ells are shon in Appendix B. They are monitored by DWR. and the U.S. Bureau of Relamation are not urrently measuring ater levels in, but have historially. Approximate latitude, longitude, and Zone UTM (Universal Transverse Merator) oordinates, in meters, for eah eil are given in Table 2. The oordinates ere determined by plotting the loation of eah eil on USGS 7.5-minute quadrangles, using information on file ith DWR. The UTM oordinates of the plotted loations ere digitied from these quadrangles. Latitude and longitude oordinates for eah eil ere alulated from the digitied UTM oordinate data using softare developed by the U.S. Geologial Survey. Loations shan in Table 2 and on Appendix B are approximate, but are estimated ta be ithin 5 feet. If you detet an error in loation, please notify the Department of Water Resoures, Northern Distrit, Ground Water Setion, 244 Main Street, Red Bluff, California

15 Ground Water Level Data Management The data presented in this report are maintained on IBM-ompatible persona! omputer systems using a olletion of data proessing appliations developed by DWR's Central and Northern Distrit Ground Water Setions. The data management appliation, knon as.. ex-terra,.. onsists of five main data tables that ontain: Ground ater levet data Generalied geographie data Weil onstrution data Weil qualifiation data Coordinate data Ex-terrais onfigured to produe both printed reports and ASCII (Amerian Standard Code for Information lnterhange) files for use in ether omputer programs. Among the printed reports are: Ground ater levels for single ells or groups of ells, based on State Weil Number, ground ater basin, or ounty Weil onstrution and monitoring history Weil oordinate and geographie data The ASCII output files are formatted for diret input to severa! idely available graphies programs to reate ground ater levet ontour maps or hydrographs, suh as those presented in Appendix A. The ground ater levet and oordinate data presented in this report an be purhased in eletroni form (see inside front aver for details). The files are provided in ASCII delimited format. An ASCII doumentation file explaining the ontents of the data files is inluded ith eah response to a data request. Information about the IBM-ompatible appliations that omprise the ex-terra ground ater levet data management system and their implementation is also available. 7

16 Ground Water Level Measurements Water levels in ali ells are measured using a steel tape or eletri probe. Ali measurements of ater levels should be aurate ta the nearest tenth of a foot. The ater surfae elevations presented in this report are alulated using the ater levet measurements and ground surfae elevations at eah eil. Most of the ground surfae elevations ere estimated from USGS 7.5 quadrangles. Auray of these elevations is dependent on the ontour intervals of the maps, hih range from 5 ta 4 feet. Ground ater levet data for eah eil are depited on the hydrographs in Appendix A. The hydrographs represent ater levet data through April 992 and are organied by tonship from south ta north and by range from east ta est. On the hydrographs, solid irles (dots) depit atual measured ground ater elevations. When an individual measurement is identified by a hollo irle enlosing a smaller solid irle, the measurement is questionable. Solid lines onneting individual measurements are interpolations of the hange in ground ater elevation beteen measurements. Disontinuities on the graphs indiate an expeted measurement is missing. Ground surfae elevations at the ells are represented as long, solid horiontal tines. Hydrographs representing monthly monitoring ells have a higher onentration of data points ompared ta hydrographs representing semi-annual measurement ells. Data points that appear.. unusual.. ere heked against field reords and retained, ta preserve the objetivity of the ground ater levet reords. 8

17 Ground Water Level Trends an be divided into to general ground ater resoure areas: the Saramento Valley, hih is the major ground ater basin, and the foothills and mountains to the east-northeast, hih have limited ground ater resoures. The Department's monitoring program foused on ells loated only in the Saramento Valley basin. Ground ater levels flutuate annually in response to pumpage, reharge from preipitation, stream perolation, infiltration of applied irrigation ater, and subsurfae inflo and outflo. Levels are usually highest in the spring and loest in the fall. Longer term flutuations our hen disharge exeeds or is less than reharge over several seasons. Changes in ground ater levels are determined from eil measurements. Hydrographs are graphial plots of the measurements and illustrate annual spring to fall hanges, long-term hanges linked to inreased or dereased ground ater extration, or variations assoiated ith et or dry limati onditions. Ground ater in is reharged by preipitation, applied ater, loal reeks, and the Thermalito Afterbay. The major reeks are Big Chiee, Uttle Chiee, and Butte Creeks. Ground ater generally flos from northeast to southest and disharges at the Saramento and Feather Rivers. ln general, the hydrographs in Appendix A sho: Ground ater levels have not hanged signifiantly sine the 95s. The seasonal flutuation (spring to fall hange) is about to 2 feet in the north and east portion of the ounty and less than five feet in the southest portion of the ounty. Ground ater level delines in most ells are assoiated ith the and urrent drought. Ali ground ater levels reovered from the to pre-drought levels during the et period in the early 98s. The deline is not just.. in the ells... Water levels in the ells indiate an apparent deline in general ground ater levais in the Chiee area. Near Chiee, an apparent ater level deline began about
