CA WATER COMMISSION: Using flood water for Managed Aquifer Recharge

Panel discusses research and strategies for using flood water with a focus on on-farm recharge

With the passage of the Sustainable Groundwater Management Act, many groundwater basins are looking towards groundwater recharge as a tool to help bring their basins into balance.  “Flood-MAR” is a resource management strategy that uses flood water for managed aquifer recharge (MAR) on agricultural lands, working landscapes, and managed natural landscapes.

At the March meeting of the California Water Commission, a panel discussed Flood MAR with a focus on using agricultural lands for groundwater recharge.  First, Kamyar Guivetchi from the Department of Water Resources discussed the Department’s efforts to advance the Flood MAR strategy; next, researcher Dr. Helen Dahlke discussed her research on crop suitability, soil suitability, and streamflow availability; then Don Cameron of Terra Nova Ranch discussed his experiences with on-farm groundwater recharge; and lastly, researcher Dr. Laura Foglia discussed a pilot project in the Cosumnes River basin.

ADAPTIVE MANAGEMENT FORUM, Part 2: How adaptive management is applied in other ecosystems

Presentations highlight structured decision making, collective action on invasive species, and a scoring system for restoration projects

Adaptive management is a strategy for making management decisions under uncertain conditions using the best available science rather than repeatedly delaying action until more information is available.  The adaptive management approach integrates learning into management decisions and providing an approach to revise projects to increase the likelihood of success, rather than implementing a project without regard for scientific feedback or monitoring. Adaptive management can be an economical and effective because it provides flexibility and feedback to manage natural resources in the face of often considerable uncertainty.

At the Adaptive Management Forum, hosted by the Delta Science Program in February of 2019, a series of presentations highlighted how the principles of adaptive management have been successfully applied in other ecosystems.  First, Sally Rudd discussed how Structured Decision Making and Adaptive Management can work together in addressing environmental and resource management problems, using two case studies to illustrate practical examples.  Next, Dr. Kurt Kowalski explained how adaptive management is being used to address invasive phragmites in the Great Lakes Basin.  Lastly, Dr. Ronald Thom spoke about a program in the Columbia River estuary that utilizes a scoring system to evaluate restoration projects.

DELTA STEWARDSHIP COUNCIL: Some good news for Delta smelt

Operation of Suisun Marsh salinity gates to benefit Delta smelt is successful; First experiments with captive-bred Delta smelt show promise

At the February meeting of the Delta Stewardship Council, some council members had questions about actions the state was taking to address the ever-declining population of Delta smelt, and particularly about the use of captive-bred Delta smelt.  At the March council meeting, Dr. John Callaway, Delta Lead Scientist, and Dr. Louise Conrad, Executive Officer of Science, updated the council members on the latest activities to help the smelt.
