From the Department of Water Resources – On a small scale, aquifers — subsurface natural basins — have been recharged with flood waters from extreme storms for decades. Now, a new Department of Water Resources (DWR) assessment shows how Flood Managed Aquifer Recharge, or Flood-MAR, can help reduce flood risk and boost groundwater supplies across large areas of land. A climate change problem solver, Flood-MAR collects high flow flood waters from heavy precipitation or snow melt and conveys it downstream. There, the flood waters are spread across the land, creating wetland habitat or irrigating fields while also percolating to aquifers underground. The capturing of flood waters during times of peak flows lessens the risk of major flooding during heavy storms. Some of the collected water is also later redirected back to waterways to support ecosystems and riverine habitat. (more)
