3 INTRODUCTION The Kings River Conservation District (KRCD) is a political subdivision of the State of California and was formed by the California Legislature with the passage of the Kings River Conservation Act in The KRCD covers an area of approximately 1,24, acres in the central San Joaquin Valley which includes portions of Fresno, Kings, and Tulare Counties. The KRCD s boundaries encompass the entire service area of the Kings River, which is the primary source of surface water for the area. The KRCD s boundaries and the study area of this report are shown in Figure 1. The study area is focused on the Kings River groundwater basin. The flow of water in the Kings River is variable from year to year. During normal (average natural flow at Pine Flat Dam assuming no interference by storage) and dry (when runoff is less than normal) years, the available surface supply does not meet the total water demand of the service area. When such a shortage of water exists, the deficiency is remedied by the pumping of groundwater which may result in a drop in the water table. During the years when runoff exceeds normal, commonly referred to as wet years, the water table may rise due a decrease in pumping and an increase in natural recharge. The conversion to high frequency irrigation systems has created a condition where some wells are in near constant (daily) operation during the irrigation season. The KRCD initiated a groundwater study in 1987 to monitor the trends within the Kings Basin. This report is a continuation in the series of groundwater reports which presents groundwater data and analysis pertinent to the KRCD on an annual basis. Prior to 199, reports were produced semiannually, one for each spring and fall measurement period. The KRCD has found that the Fall depth to groundwater data was too inconsistent in the number of wells reported to generate an accurate groundwater surface. As the Spring data is more comprehensive and generally collected in a narrower time window, the KRCD has elected to prepare Spring to Spring comparison reports for the basin.

4 OBJECTIVE The objective of this report is to present groundwater conditions within the Kings River groundwater basin (referred hereafter as study area ) as they existed during the Spring of 213, and to compare those conditions with previous years. It has been determined that a fixed point is necessary to establish long term trends in the groundwater supply, so the conditions present during the Spring of 23 will be the reference point for this and future reports, until such time as significant changes to the methodology used are made. The advent of the CASGEM (California Statewide Groundwater Elevation Monitoring) program in 211 along with the inclusion of data generated in accordance with the SB 1938 groundwater management plans for the Kings Basin will substantially alter the content of this report, allowing for the establishment of new baselines. Due to the low quality/quantity of the Fall data obtained, comparisons from Fall to Fall will not be analyzed in this report. A review of the Fall data available shows considerably less well data for the region when compared to the Spring data, and thus the quality of the maps would be degraded due to the increase in interpolation needed to generate water level contours. Actual recorded water depths used in this report are attached in Appendix One. Kings River Conservation District Annual Groundwater Report Page 2

5 GROUNDWATER STUDY The basis for the groundwater study is data derived from measurements of the depths to groundwater in wells throughout the Kings River groundwater basin. The measurements are taken by a variety of local, city, state, and federal agencies. The data is supplied to the KRCD by the California Department of Water Resources (DWR). Not all of the wells within a geographic area are sampled every year, for a variety of reasons. Those data points were eliminated from the database prior to analysis. Common reasons for exclusion include but are not limited to the following: pump in operation, pump recently in operation, pump not accessible, sounding not possible at time of sampling, and sampling not possible within sampling window. In order to perform a groundwater study that is focused on the Kings River service area, a roughly defined buffer is established around the known boundaries of the KRCD, and any wells outside of this buffer are excluded. A detailed explanation of the well selection and map creation process is listed in Appendix A. It is known from previous studies that groundwater anomalies exist south of the Kings River channel, and every effort to exclude these data points was made so as to insure that the contours presented are accurate. These anomalies have been determined to be multiple aquifers (one unconfined, two confined) present just south of the Kings River channel and the uncertainty of the well construction of the monitored wells in that region. The Tulare Lake basin, while inside the Kings River service area, is excluded from the current analysis due to the lack of wells, the depth of the construction of the wells within that region, and the general makeup of the soils (moderate to heavy clays). It is for these reasons that the study area of this report is defined as the region between the Kings River to the south, Westlands Irrigation District to the west, the San Joaquin River to the north, and the eastern boundary of Alta Irrigation District to the east. It should be noted that the data contained within this report is only comparable to data contained in similar reports from Fall 1989 on. Prior to that report, a 14, acre section of what is now the KRCD service area was not included within the groundwater storage calculations, as it resided outside of the then district boundaries. When analyzing the groundwater data that is compiled by the Bureau of Reclamation (Bureau) or other sources, it is important to realize that there are several factors which can lead to the lack of quality control of the data that has been collected. First, the complexity and size of the data collection program can lead to less than perfect results. Second, variations in measurement technology, expertise of personnel and date of measurements among the agencies, can contribute to the lack of quality control in data collection. A final factor that contributes to inaccurate data is the lack of information regarding well construction. Many wells are driven through several water bearing formations and are screened for long distances. Therefore, some data may represent a composite of depths to water for confined and unconfined aquifers and not the depth to water in a specific aquifer. Multiple formations are more common near the Kings River, Kings River Conservation District Annual Groundwater Report Page 3

6 thus leading to the exclusion of data to the south of the channel. The CASGEM (California Statewide Groundwater Elevation Monitoring) program is designed to eliminate many of these factors. Figure 1 shows the two management areas that the KRCD established when these areas were annexed into the district. As the District is now working on a whole basin approach under the requirements of SB 1938 and CASGEM and its parallel Integrated Water Management Plans for the Upper Kings Basin, these areas will be merged into a single special study area with additional monitoring done by KRCD staff. Future improvements to this report will include a description of the establishment of a subsidence monitoring grid (along with data when available), an expansion of the area covered to include the Tulare Lake Basin, and the identification of representative wells and hydrographs showing long term trends. Incorporation of longer term historical data is also planned to improve the evaluation of the groundwater trends within the basin as a whole. Volume changes within the study area will be based upon readings taken at the same well on a year to year basis, so that the same sampling points exist during the report period (i.e. well A is to be sampled in both Spring sampling events to generate a change in depth, not the current practice of averaging the available well soundings across the basin to estimate the volume change). This change in methodology will make this report comparable to other reports produced within the State. As time permits, a review of previous reports may be attempted. Additional improvements include a more complete estimation of specific yield within the basin. Specific yield varies from one portion of the basin to another, and data now exists (not yet processed) so that well data within specific polygons can be correctly interpreted as to exactly how much water was extracted. The yearly consumption within the basin would then be a sum of these various polygons. Given enough time, this method could be applied backwards to previous reports and generate an improved estimate of groundwater consumption over longer periods. Funding sources are being identified for the construction of dedicated monitoring wells within the basin, thus insuring that comparable data points will exist in future reports. The integration of CASGEM data into this report will allow for the evaluation of Fall to Spring recovery rates, plus a more detailed analysis of the rate of depletion from Spring to Fall. We should also see the impacts of flood operations on the Basin much sooner and in greater detail. To date, we have updated the local surface elevations for the selected monitoring locations, plus we have established the control grid for the subsidence work and are currently selecting appropriate benchmarks within that grid to periodically measure.

7 RESULTS As stated above, this report does a comparison of the conditions present in the Spring of 214 to those in the Spring of 213. For this timeframe, there was a net decrease in storage of approximately 896,33 AF. The drier than normal winters following the flood releases in 211 has forced the consumption of the 211 recharge and increased the depletion of the available groundwater basin wide. This figure is down considerably from the estimate of 1,19,112 AF. The groundwater depression in the western basin has expanded its deepest contour lines (22 ft.) between 213 and 214 (Figures 2 and 4). The zones of shallower water between Raisin City, Caruthers, and Easton have remained static, as has the general location of the 2 ft. contour. The groundwater mound that exists around the Fresno Waste Water Treatment Plant has reappeared in 214, after disappearing in 213. Groundwater levels are also falling around Tranquility and San Joaquin in response to reduced deliveries from the Delta-Mendota Canal. Depth to water is increasing near Biola as the region that once showed 6 ft. to groundwater is now a uniform 8 ft. Further east, the area covered by 4 ft. depth to groundwater near Reedley has receded, with much of the area from Reedley to Dinuba now showing 6 ft. to groundwater The map shown in Figure 6 shows that for the time period, the majority of the groundwater basin shows very few areas with no change, large tracts with a 2 or 4 ft. increases in depth to groundwater, and smaller areas showing a 6, 8 and even 1 ft. depth to groundwater increase. Some areas show increases in groundwater storage over this period, but they are widely scattered and generally only 2 feet over the 1 year study period. The estimated change in storage for the 23 to 214 time period is a decrease of 3,166,439 AF, or 287,858 AF per year. It should be noted that in Figures 6 and 7 that a disturbingly large drop in groundwater levels is being reported in the southwestern part of the basin. The KRCD has low confidence levels of this region due to the lack of reporting wells in the area. Kings River Conservation District Annual Groundwater Report Page 5

8 Future Reports The Report will begin the process of incorporating an analysis of subsidence within the groundwater basin, as well as bringing back the Spring and Fall water level analyses to this report. A change in groundwater storage methodologies will also be implemented. GIS analysis allows for the use of more accurate specific yield estimates as polygonal sections within the basin. The current report uses an average value of 11.6% for specific yield, where future reports will allow for the consideration of zones with both higher and lower specific yield values. The report may also contain the return of changes in groundwater levels by KRCD Director district. This analysis can provide a more detailed look at water consumption by region within the Kings Basin. The static water table will be determined using identical sampling points on a year to year basis, rather than interpolated results from multiple wells that may or may not correspond to each other. The potential installation of additional dedicated monitoring wells will insure that representative points throughout the groundwater basin will be included, with the initial focus being on zones with poor existing coverage. The use of agricultural production wells will continue as they represent the only source of groundwater data available. Increased security measures by the owners of these wells (locked enclosures) and the increased use of high efficiency irrigation systems (pumps in daily operation rather than periodic) has caused the loss of some wells as sampling points over the past few years. We hope the future installation of dedicated monitoring wells will address these issues. Additional efforts in groundwater monitoring are mandated in the General Order of Waste Discharge for the Tulare Lake Basin (Order number R ) issued by the Central Valley Regional Water Quality Control Board in September 213. How this will impact the quality of these groundwater reports is currently unknown. Additional monitoring in the eastern portions of the groundwater basin is likely, as well as additional measurements throughout the basin from both agricultural production wells as well as some domestic water wells. Groundwater quality results may be included in future reports where plots of EC, ph, and nitrate content of the groundwater may be published. The KRCD has completed the process of physically locating existing benchmarks to infill the survey grid created by the known reference stations for the land subsidence studies. This study is mandated by the requirements of SB 1938 for groundwater management plans. The specific methodology for the survey and data analysis will be included with that report. With the development of the CASGEM program, KRCD acts as the reporting agency for groundwater data in the Kings, Tulare Lake, and portions of the Tule River and Delta-Mendota (Tranquility ID) sub-basins. The KRCD coordinates the sampling times, collects and formats the data, and reports the results to DWR twice yearly. Since Kings River Conservation District Annual Groundwater Report Page 6

9 the KRCD can guarantee that the data is collected and that the windows of collection are as narrow as possible, the quality of the data collected will be improved. Kings River Conservation District Annual Groundwater Report Page 7

10 CONCLUSION The overdraft of the Kings Basin continues to be a major long term problem. The effects of the and the water years slowed the decline, but they no longer impact the observed data. The cutoff of State and Federal water to the Westside appears to have accelerated the decline in the western portions of the basin. The continuing drop in groundwater storage is highly indicative of the increasing demands upon the groundwater resources of the basin and the need to improve groundwater recharge capacity throughout the basin. Additional structures need to be built to contain and distribute flood releases (conjunctive use, in lieu recharge) from the Kings when available, thus promoting recharge of the aquifer. Additional conveyances should also be considered to move water from known areas of artificially high water tables to those areas where overdraft is having a severe impact.
