What’s the Potential for Increased Groundwater Replenishment in California?

Panel at ACWA highlights state efforts to scale up Flood Managed Aquifer Recharge, survey on groundwater recharge in the Central Valley, and ACWA’s groundwater replenishment initiative

With implementation of the Sustainable Groundwater Management Act (SGMA) fully underway, the newly formed Groundwater Sustainability Agencies (GSAs) now turn their attention to developing Groundwater Sustainability Plans (GSPs) for their basins.  For basins that are critically overdrafted and many others, bringing groundwater basins under sustainable management while maintaining current acreage in production means finding a way to recharge their basins.

At the the recent ACWA conference, a panel of groundwater experts discussed the potential for increasing groundwater recharge across the state.

On the panel:

  • Kamyar Guivetchi, manager of Statewide Integrated Water Management from the Department of Resources;
  • Sarge Green, a member of the Research Network with the Public Policy Institute of California and the Water Policy Center;
  • Timothy Parker, Executive Director of the Groundwater Resources Association; and
  • Eric Averett, General Manager of the Rio Bravo Water Storage District and vice-chair of ACWA’s groundwater replenishment initiative.

California floodplains and the fish that use them

How restoring functional flows to floodplains could help restore native fish

Two centuries ago, the floor of the Central Valley was largely a marshy wetland.  In the springtime, the snowpack would melt, swelling the rivers beyond their banks and casting the young fish out onto the floodplains.  There they would stay for months, fattening up on the abundant zooplankton and invertebrates until the floodplains drained, signalling the time to migrate to the ocean.  However, the construction of levees to control flooding of cities and farmland also separated the rivers from their floodplains, denying access to native fish who have evolved to take advantage of the habitat.

In this brown bag seminar, Dr. Carson Jeffres discusses how historically California’s native fish have evolved to take advantage of floodplain habitats in the Central Valley, and how restoring the connection of the rivers to the floodplains can help restore struggling fish populations.
