What is the Sustainable Groundwater Management Act?

The Sustainable Groundwater Management Act (SGMA) requires that California groundwater basins identified as high or medium priority establish a Groundwater Sustainability Agency by June 30, 2017, and develop a plan for sustainable management by January 31, 2022. If the local GSAs fail to follow the timeline, then the State Water Resources Control Board will step in and intervene in local groundwater management. SGMA defines sustainable management as:

“Management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results.”

The Petaluma Valley GSA will be tracking six main sustainability indicators:

Lowering Groundwater Levels

 

Seawater Intrusion

 

Reduction of Storage

 

Land Subsidence

 

Degraded Groundwater Quality

 

Surface Water Depletion
