Quantifying the Impacts of Sustainable Groundwater Management: Modeling Financial Losses from Groundwater Reductions in the Lower Santa Clara River Valley

by Burns, Beau

Abstract

This paper presents results from an economic-groundwater model developed for the Oxnard, Las Posas, and Pleasant Valley groundwater subbasins. Located in Ventura County, California, these subbasins are experiencing issues relating to groundwater overdraft. Due to the Sustainable Groundwater Management Act (SGMA), each subbasin must create strategies to address groundwater overdraft. This model informs potential strategies by simulating three scenarios: (1) a baseline scenario using current water allocations, (2) a scenario where groundwater allocations are restricted 20% and farmers have the ability to import surface water to replace their groundwater, and (3) a scenario where groundwater is restricted 20% and farmers cannot import water. This study finds that scenario 2 generates the least financial losses, although the difference between the scenarios 2 and 3 is unsubstantial. The total financial losses for agricultural producers under scenario two are: $9,450,269 (a 31% decrease) in Oxnard, $637,499 (a 29% decrease) in Pleasant Valley, and $19,932,643 (a 45% decrease) in Las Posas.
