Do we have measurement of that? How worse does it get on overdraw?
- dylan604 3y agothere have been articles/posts with showing just how much the ground has compacted or sunk. "overpumping caused land in the state's San Joaquin Valley to sink almost 3 feet (85 centimeters) during a recent drought from 2007 to 2010."

Since the 1920s, sections of the San Joaquin Valley have sunk by as much as 8.5 meters (28 feet). Groundwater pumping becomes even more problematic during droughts, exacerbating subsidence problems. Data from 2015 showed some spots subsided at rates as high as 600 millimeters (2 feet) per year." https://www.washingtonpost.com/climate-environment/2023/05/30/land-sinking-us-subsidence-sea-level/ https://www.washingtonpost.com/climate-environment/2023/05/3...
