DWR groundwater levels report shows mixed results

Although Spring 2017 groundwater levels have mostly recovered from last year, most have not yet recovered to pre-drought conditions

Although Water Year 2017 was one of the wettest on record, it’s impact on groundwater levels across the state is varied, according to a report issued by the Department of Water Resources on Friday.  While spring groundwater levels have mostly recovered from the last year, most groundwater levels have not yet recovered to pre-drought conditions; the deeper, more severely depleted groundwater basins will take years to recharge.

The data shows that as of spring 2017, most groundwater levels across the state had recovered to Spring 2016 levels, with a little over half (56.7%) showing less than 5 feet of change in groundwater levels.  About 5% of wells measured had an increase of 25 feet or more; only 1% had significantly lower groundwater levels (25 feet or more) as compared to spring of 2016.

When comparing spring 2017 measurements to spring 2011 measurements, only 1.2% had significantly higher groundwater levels; 16.3% had significantly lower groundwater levels.  Approximately 47.6% of wells had less than 5 feet of change.

BROWN BAG SEMINAR: Developing Tiered Environmental Flow Criteria Using a Functional Flows Approach for California Streams

Establishing environmental flow targets to protect aquatic communities is a priority for numerous programs in California including in the Delta. In this first of three brown bag seminars focusing on flow targets and ecology, Dr. Yarnell discusses her recent work using a functional-flows approach to develop statewide environmental flow recommendations. The approach allows for the rapid development of flow regimes that consider ecosystem and human needs and can be applied in an adaptive management framework, allowing for changing conditions and needs.

Dr. Sarah Yarnell is a research hydrologist with the Center for Watershed Sciences at the University of California Davis.  Her research focuses on integrating the traditional fields of hydrology, ecology, and geomorphology in the river environment.  She is currently working with a broad coalition of academics, researchers, and resource managers to develop the California Environmental Flows Framework, which has been in process over the past year.
