This data represents the subsidence monitoring locations within the Central Valley used in the Fine-Grid California Central Valley Groundwater - Surface Water Stimulation Model (C2VSimFG) to calculate the groundwater storage loss due to compaction. The purpose of the dataset is to allow the Sustainable Groundwater Management Act (SGMA) interested parties and the public to use the C2VSimFG's output data to assist in the implementation of their groundwater sustainability plan. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The data set is used as the C2VSimFG observed subsidence data to compare with the simulated subsidence data to evaluate the impact on subsidence, groundwater budgets, and groundwater levels. The subsidence affects stream-aquifer interactions and the decline in groundwater storage due to compaction in the San Joaquin Valley and Tulare Lake Basin. The data contains observed subsidence data over time from the DWR and USGS stations, USGS InSAR RestoreSJR GPS stations, USGS Extensometers, and the Continuous UNAVCO PBO GPS dataset. Most of the observed subsidence data was monitored with almost daily intervals. The GPS Surveys by USGS InSAR RestoreSJR monitoring subsidence stations were monitored biannually. The DWR continuous effort in the subsidence monitoring is part of the Sacramento Valley Subsidence Network, consisting of over 300 monument locations with an average spacing of 4.3 miles, encompassing 11 counties.</SPAN></P></DIV></DIV></DIV> |
