Antelope Subbasin Groundwater Sustainability Plan is Incomplete C: 0 .l,l . "' Many groundwater wells within the Antelope Groundwater Subbasin have gone dry apparently a:: :: as a result of the decommissioning of the Diversion Dam. The GSA appears not to have taken u.. into consideration public information regarding the effects the Diversion Dam had on ..;.,.; groundwater recharge in the Antelope Subbasin, both during and after its decommissioning, C: E when drafting the Antelope Subbasin Sustainability Plan. .c: " ! The District's Response to FG: The District partially disagrees with the finding. The drying of Lake Red Bluff had a clear and predicted effect on groundwater levels in the Antelope subbasin. Monitoring wells in the area indicate a drop of up to 14' in the water table locally. This is an unfortunate ramification of a Federal project which occurred prior to the adoption of SGMA by the California Legislature and would not be considered when drafting the GSPs. RG.a Research Dry Well Correlation to Diversion Dam Decommissioning The Grand Jury recommends the TCFC&WCD, in cooperation with the County Environmental Health, research the dry well areas in the Antelope Subbasin. The question should be answered whether there is a correlation between dry wells in the Antelope subbasin and decommissioning of the Diversion Dam. This research should cover an appropriate period of Packet Pg. 9 96 3.1.a time before and after the decommissioning, as well a representative radius of influence from the dam and Lake Red Bluff. The District's Response to R6a: The recommendation will not be implemented because it is not warranted. No research is necessary to clearly see the dam's decommissioning's effect on wells. The dam was decommissioned in 2013 and dry well reports in the area began in 2014. Many wells east of the East Sand Slough were shallow and quickly lost access to water. The radius of the lowering is indicated in our existing monitoring well system.
