A watershed-related issue examined by the ENVS 560/L Watershed Systems class at CSUMB.

Summary

Over 524 thousand acre-feet of groundwater was extracted during the 2014 water year, 91.55% of which went to agricultural use and 8.45% for urban use.[1] The high dependence on groundwater for agricultural water needs in the Salinas Valley has led to critical overdraft conditions[2] that have resulted in abandonment of agricultural and urban supply wells due to rising salinity levels[3]. Groundwater overdraft can lead to numerous problems such as seawater intrusion, aquifer storage reduction, loss in groundwater quality, and lowering of water levels.[4] The concern over these adverse effects has led to the development of a statewide groundwater management plan[5] and new supplemental water supplies from the Salinas Valley Water Project.
