Fall 2024 Groundwater Levels in the Yolo Subbasin
The YSGA's 62 Representative Monitoring Wells throughout the Subbasin are each measured at least twice per year. The graph above shows the average water depth among all 62 wells and represents the general condition of the basin.
Fall 2024 water levels are similar to where they were last year around this time, however, this year's seasonal drawdown from spring to fall was much larger than that of 2023. While conditions have improved significantly from the historic 2020-2022 drought, it will take several years for the groundwater to fully recover from the drought. Average groundwater levels this fall are still around seven feet lower than that of Fall 2019.
