In our newest paper on "Navigating the Growing Prospects and Growing Pains of Managed Aquifer Recharge" we not only discuss benefits but "how can we integrate recharge into the broader legal-economic-institutional system and ensure equitable outcomes."

Navigating the Growing Prospects and Growing Pains of Managed Aquifer Recharge
Increasing water demands and declining groundwater levels have led to rising interest in managed aquifer recharge. That interest is growing in the United States—the focus of this article—and elsewher...

Big Colorado River news: “Arizona will again go without 18% of its total Colorado River allocation, while Mexico loses 5%. The reduction for Nevada will stay at 7%. California won’t face any cuts because it has senior water rights and is last to lose in times of shortage.” apnews.com/article/colo...
Arizona, Nevada and Mexico get less Colorado River water for a third year
Federal officials say Arizona, Nevada and Mexico must again live with less Colorado River water as drought lingers in the West.

Flood managed aquifer recharge paired with forecast-informed reservoir operations led to a 40-60% reduction in aquifer overdraft. That’s pretty significant! But still need to reduce withdrawals.
Screenshot of article text that reads: “Essentially, Flood-MAR uses the aquifer as an underground reservoir that increases the total storage capacity of the watershed. While this practice alone cannot solve the water crisis, the study found that combining it with Forecast-Informed Reservoir Operations (FIRO) and strategic infrastructure investment can achieve a 40% to 60% reduction in groundwater overdraft”

Our latest publication is out estimating the transport of pesticide residue under on-farm recharge in a deep (70 m) vadose zone using #towTEM data. Thiamethoxam is most mobile (rain or recharge), while Methoxyfenozide is mostly mobilized during flood recharge.

Governor Newsom is issuing again the capture of flood water for groundwater recharge and storage! www.gov.ca.gov/2025/01/31/g... If you want to recharge water on your land take a look at our Soil suitability index casoilresource.lawr.ucdavis.edu/sagbi/ and consult floodmar.org to learn how to!

If you wondered what flooding farm fields for groundwater recharge looks like, here are a few pictures. It often also called on-farm recharge, agricultural managed aquifer recharge (Ag-MAR) or flood-managed aquifer recharge (Flood-MAR).

How to start new on a new platform? My group is researching intentional groundwater recharge, specifically how to capture millions of gallons of water from atmospheric rivers by flooding farm fields with flood water using existing, gravity fed water conveyance.
