Below is the evaluation summary for the 15780 N. Clements Irrigation Well (APN 05319001) -well <br /> permit application. <br /> The evaluation, with assumptions as noted, indicates that the proposed Irrigation well is located in an <br /> area of low domestic/residential well density(1 well per section), General Plan designation AG-40 (0.0— <br /> 0.05 Dwelling units per acre) but is not likely to interfere significantly with existing off-site wells, create <br /> unreasonable groundwater level declines/reductions in aquifer storage or to create issues with <br /> infrastructure due to subsidence and it can be approved pending any other issues that you might have <br /> with the application. <br /> Summary: <br /> - The applicant proposes: well depth of 500 feet, a well grout seal of 50 feet with extraction rate— <br /> 600 GPM with anticipated pumping schedule 360,000 Gal/day in a 150 acre lot. <br /> - Proposed new well is in an area of low domestic/residential (0.0 —0.05 Dwelling units per acre) <br /> well density(6 wells in section T3N\R8E\11). At least one domestic well is located approximately <br /> 500 feet Southwest of the proposed Ag well <br /> - Based on the extraction rate of 600 GPM, The Theis drawdown chart predicts less than 5 feet of <br /> drawdown if the well is more than 200 feet away from proposed well. <br /> - Review of aerial imagery indicates an irrigation well is present approximately 650 feet Northwest <br /> of the proposed Ag well. <br /> - Groundwater levels estimated by DWR well data range between 130 (04/01/2011) to 159 <br /> (10/1/2020)foot below ground surface over the past fifty years.Water levels fluctuate <br /> approximately 3 to 9 feet between seasonal high and low levels. <br /> - The permit application proposes a minimum well casing/grout seal of 50 feet and appears to <br /> target the Turlock Lake aquifer with water-bearing zones anticipated to be under unconfined to <br /> locally confined conditions. <br /> - The annual total extracted volume is estimated to be approximately 146.6 million gallons, a <br /> peak pumping rate of 1746 GPM, and an annualized/seasonal pumping rate of approximately <br /> 485 GPM. <br /> - The aquifer volume below the 150-acre parcel contains an estimated 13,955 acre-feet of water <br /> storage.The proposed extraction volume of 450 acre-feet per year is approximately 3.2%of the <br /> estimated aquifer storage beneath the parcel without regard to recharge each season and is <br /> considered sustainable. <br /> - The proposed well is not located within the extents of the Corcoran Clay, subsurface water- <br /> bearing sediments are semi-consolidated to consolidated, and the proposed well is not located <br /> in an area where subsidence is currently indicated,therefore subsidence is unlikely to be of <br /> significance or to create issues. <br />
