Groundwater levels are measured in the YCFCWCD's 150 well network each spring and fall. The graph above shows the average groundwater level of the wells with long periods-of-record. This spring's 2021 levels showed minimal recovery, as expected, after a dry winter and spring. 

Groundwater levels are measured in the YCFCWCD 150 well network each spring and fall. The graph above show the average groundwater level of all the wells. This fall's 2020 levels dropped, as expected, after a long summer with no rain. 

As expected, not much recharge. A typical scenario for a dry winter with below average precipitation.
