In recent years, the State of California has experienced historically low rain fall and hot summers leading to a four year or longer drought. These drought impacts have become acute across many areas of the state as water stored in reservoirs was depleted and water levels in groundwater basins declined.

In early 2014, the Governor declared a state of emergency. As a result, the California Legislature enacted the Sustainable Groundwater Management Act of 2014 in September 2014. This act established statewide framework for the sustainable management of groundwater resources, which focuses on granting new authorities and responsibilities to local agencies. Ensuring water supply reliability and long-term groundwater sustainability has become even more important as a result of the long-term drought and the reduced availability of State Project Water from Northern California.

In 2015, local water agencies began meeting to identify and develop a Groundwater Sustainability Council for the San Bernardino Basin Area, now known as the San Bernardino Basin Groundwater Council. The goals of the Groundwater Council are to prepare for and coordinate the management of groundwater supply resources throughout the Basin, and to coordinate maintenance of conveyance and recharge facilities to expedite such management.
