OutlineGroundwater basin managementSustainable Groundwater Management Act
(SGMA) provisionsWho is affected?What can Cities do?
Groundwater Basin Management
Considerations in Managing a Groundwater BasinLand Use; overall water demandWater rightsEnvironmental Considerations (water quality,
surface water interaction with groundwater, other)
Land SubsidenceStorm water capture and availability of
supplemental waterOther depending on local conditions
A brief history of Chino Basin (and many others?)
Land use has changed over time
Consider the changes from the perspective of water supply and demand
1978 JudgmentEstablished the Safe Yield of the BasinAllocated rights according to priority
Overlying land ownersAppropriators
Provided for orderly transfer of agricultural rights to appropriators
Created a Watermaster
2000 Optimum Basin Management ProgramCreated in the late 1990’s as a result of
growing dissatisfaction with results of basin management
Identified essential goals for management of the Basin:Enhancement of water suppliesProtection/enhancement of water qualityProtection against further land subsidenceEquitable financing
What is a groundwater basin adjudication?
How does a groundwater basin get managed without
an adjudication?
SGMA ProvisionsAdjudicated BasinsNon-adjudicated basins
SGMA ProvisionsAdjudicated Basins…Are required to submit the Court Order to the
State and annually provide information such as groundwater pumping, water levels, and change in storage.
SGMA ProvisionsNon-adjudicated basins…Are required to form a Groundwater
Sustainability Agency with authority to require registration of wells; measure and manage pumping; require reporting and assess fees;
The GSA must prepare a Groundwater Sustainability Plan, which includes maps and information about the basin; objectives with a timeline, monitoring, and relationship to other local government plans
SGMA ProvisionsNon-adjudicated basins…GSA must be formed within next 2-3 yearsGSA must adopt GSP by 2020GSP must achieve sustainability by ~2040Or else…
Who is affected
What Can Cities Do?The SGMA is addressing one part of a bigger
picture.What’s the big picture?
Borrowed from: Cooperative Institute For Meteorological Satellite Studies
In case the SGMA applies to your region, be sure to engage in the Groundwater Sustainability Agency and help with the Sustainability Plan; and
Help manage demand within your boundaries
How Can Cities Influence Demand?Can land development include Water Use
Efficiency requirements?Can land development enhance MS4
requirements and increase stormwater capture?
Are water conservation ordinances realistic, enforceable, and coordinated with neighboring Cities?
