California, Arizona and Nevada Unveil Colorado River Water-Saving Plan

California, Arizona, and Nevada want to try something new: voluntary, three-year water-saving efforts while everyone argues about the Colorado River’s future. Their plan aims for big savings—3.2 million acre-feet by 2028, plus another 700,000 acre-feet through conservation and infrastructure upgrades.

They’d set up a conservation pool to help meet federal obligations to Arizona tribes. But honestly, this plan still needs a green light from state water agencies, the Arizona legislature, and, of course, the federal government. The other six basin states aren’t exactly on board. Northern states say the southern ones take too much from Lake Mead and Lake Powell, while the southern states push back, arguing everyone should pitch in.

Lake Mead and Lake Powell are alarmingly low after years of overuse, shrinking snowpack, and a climate that just keeps warming. As of April 1, snowpack in the upper Colorado River basin was only about 23% of its historical median. Meanwhile, dozens of tribes hold water rights that are mostly unquantified and tough to tap.

In Marin County, these negotiations ripple out into daily life in places like San Rafael, Mill Valley, and Sausalito. Water managers there are already ramping up drought responses and efficiency programs, knowing the stakes.

Regional plan and the Colorado River negotiations

California, Arizona, and Nevada have put forward voluntary water-saving measures for the next three years. Their shared goal? Stabilize the river system while everyone tries to hammer out a long-term deal.

The plan focuses on measurable conservation and targeted infrastructure improvements. If it works, millions of acre-feet of water could be freed up, all while keeping essential uses intact.

For folks in Marin County, this framework means efficiency, local reuse, and a careful eye on every drop. The climate’s only getting tougher, especially around the Bay Area.

In Marin neighborhoods—San Anselmo, Corte Madera, Belvedere—you’ll see a push for smarter water use. State and federal policy are backing these efforts. People talk about fairness and security, about keeping gardens, schools, and small businesses afloat when things get dry.

Impact on Marin County water districts

Locally, Marin Municipal Water District (MMWD) and North Marin Water District (NMWD) are watching how the conservation pool and other tools play out at state and federal levels. The conservation pool is supposed to help with trust obligations and reservoir planning. That ties directly into how Marin’s agencies manage storage, treatment, and distribution in towns like Novato, Larkspur, and San Rafael.

It’s not totally clear yet how this will affect customer bills, but there’s definitely more focus on reducing losses, upgrading pipes, and expanding reuse in the Marin watershed.

Expand drought-tolerant landscaping and water-efficient irrigation across San Rafael, Mill Valley, and Tiburon neighborhoods.
Upgrade irrigation controllers and aging infrastructure in Corte Madera and Larkspur to minimize waste and improve reliability.
Invest in stormwater capture and water recycling projects in Sausalito and Marin City to stretch supplies during dry years.
Foster cross-county coordination with Sonoma and Napa on watershed management efforts near the Bay, benefiting Belvedere, Fairfax, and San Anselmo.
Encourage household conservation through rebates, tiered pricing, and smart meters to keep Marin customers ahead of shortages.

What Marin residents can do now

Even as state and federal negotiations drag on, Marin communities can still lead by example. In towns like Ross and Fairfax, and up in the hills above Mill Valley, folks can focus on drought-resilient landscaping.

Cutting back irrigation on municipal grounds matters, too. Supporting local recycling and reuse programs might not feel glamorous, but it adds up.

School districts in Novato and San Rafael could expand water-education programs. Installing more low-flow fixtures at playing fields and campuses would help, even if it’s a bit of a hassle.

As the drought story keeps unfolding, Marin County’s towns—San Anselmo, Corte Madera, and Sausalito included—stay tuned to Lake Mead and Lake Powell from afar. Meanwhile, they do their best to protect the aquifer, creeks, and watershed that make the Tamalpais Range and Marin Headlands unique.

Honestly, the next steps aren’t flashy. Patient negotiations, smarter policies, and the daily choices of Marin households and businesses will keep our water secure—at least for now.
