Management of California’s groundwater basins is fragmented, and many groundwater management plans are outdated and lacking important details, leaving significant room for improvement, according to a report released today by the California Water Foundation (CWF). The report, An Evaluation of California Groundwater Management Planning, assesses the current condition of groundwater management planning in the state and makes recommendations to support sustainable management.
“California’s limited approach to groundwater management has been a concern for a long time, but the drought has drawn renewed attention to this increasing problem,” said Lester Snow, executive director of CWF. “Developing effective plans for how we manage this valuable resource is a crucial step to ensure that California’s farms, cities, and environment have reliable water supplies today and in the future.”
Groundwater is a critical part of California’s water supply, used to meet approximately 40 percent of the state’s water demands in an average year and up to 60 percent or more during droughts. In some regions, groundwater provides 100 percent of the local water supply. Yet, California is the only state without comprehensive statewide groundwater management programs.
The report released today reviewed 120 groundwater management plans adopted by local water agencies to manage their groundwater basins and concludes that current state groundwater management laws are inadequate. While many districts are effectively managing their groundwater resources, the report found significant limitations to the overall quality of groundwater plans in all parts of the state. Many plans lack basic basin management objectives or an implementation strategy for ensuring that objectives will be met. Most of the plans did not include or describe stakeholder outreach and participation. Additionally, 28 percent of the plans examined were written in 2002 or earlier and have not been updated.
The report makes the following recommendations to advance the development and implementation of groundwater management plans:
Establish a statewide goal that groundwater plans must describe how they will achieve sustainability of each groundwater basin.
Organize and empower local groundwater agencies to manage groundwater sub-basins.
Require the development and enforcement of groundwater management plans by local groundwater agencies.
Provide local agencies with technical guidance and financial support from the state of California.
Empower the state of California to oversee program implementation.
The state’s growing groundwater overdraft problems have resulted in a number of adverse consequences, including saltwater intrusion, increased energy costs due to pumping from greater depths, environmental degradation, and land subsidence that results in costly damage to infrastructure.
The California Water Foundation’s (CWF) vision is to sustainably meet the water needs of California’s farms, cities, and environment today and into the future.CWF supports innovative projects and policies and brings together experts, stakeholders, and the public to achieve 21st century solutions.
