Estuaries—places where rivers meet the ocean—are some of the most important ecosystems in the United States, supporting coastal economies, protecting communities, and serving as nurseries for much of the nation’s seafood.

In this episode from the Reservoir Center in Washington, D.C., Daniel Hayden, CEO of Restore America\'s Estuaries, explains why these places—from Chesapeake Bay to Puget Sound – are essential to nature, the economy, and people.

Hayden highlights collaborative restoration efforts across the country, including eelgrass recovery in Morro Bay, oyster shell recycling programs in Gulf Coast communities, and wetland restoration projects led by tribal partners along Long Island Sound. The conversation also explores how restoring abandoned cranberry bogs in New England is reconnecting wetlands to nearby estuaries and bringing native ecosystems back to life.

Along the way, Hayden explains how partnerships with federal agencies, nonprofits, and local communities are driving long-term progress—showing that with sustained investment and collaboration, damaged waterways can recover and once-polluted urban rivers can become vibrant places for people and wildlife again.

Water is emerging as a defining factor in U.S. economic growth and national security—from where data centers and energy projects can scale to how communities absorb the rising costs of floods, droughts, and insurance risk.

In response, a new Aspen National Water Strategy has been released, laying out a plan to rethink how the country manages water. This episode is a conversation with the co-leads for developing the strategy, Martin Doyle of Duke University and Newsha Ajami of Lawrence Berkeley National Laboratory.

Their central argument is a shift in framing: water is not just an environmental or local utility issue—it’s a core economic input and a strategic asset. The discussion explores how that plays out today, from AI and energy demands tied to water availability to insurers effectively redrawing the map of risk across the country. It also gets into what’s holding the system back, including fragmented governance, outdated infrastructure models, and policies that don’t align with how water actually moves through watersheds.

The strategy outlines priorities including governing for outcomes instead of process, investing in rural landscapes that underpin national water supply, and expanding infrastructure to include natural systems, data, and people.

Doyle and Ajami also highlight the need to remove barriers to adopting solutions that already exist, and to rethink financing and business models so innovation can scale.

It’s a clear-eyed look at how water is shaping the economy and risk landscape today—and what it will take to treat it as the national priority it has become.

California’s water system was built for a wetter century—and now the state is racing to turn wastewater into a reliable part of its supply portfolio. In this episode, Joaquin Esquivel, chair of the California State Water Resources Control Board, breaks down where water reuse fits in California’s long-term strategy, and what it will take to scale it safely and affordably.

The conversation spans the state’s role as both regulator and funder, including the adoption of direct potable reuse regulations, the safeguards designed to protect public health, and the need for “regulatory certainty” that helps projects move from concept to construction.

Esquivel also shares the numbers behind California’s current reuse footprint—roughly 750,000 to 800,000 acre-feet annually—and the state’s goals to expand that supply in the coming decades while balancing discharges needed for instream flows. The episode tackles the “yuck factor” head-on, explaining why monitoring, testing, and transparent communication are essential to maintaining trust as systems move toward direct connections.

And it spotlights a looming constraint few people see coming: a major wave of retirements that could reshape the water workforce just as advanced treatment becomes the new normal.

In Sacramento, the shift to viewing wastewater as a critical resource is transforming regional water security and ecological health.

In this episode, Christoph Dobson, General Manager of Sacramento Area Sewer District, explains how the landmark $1.7 billion EchoWater project has elevated treatment standards to tertiary levels, protecting the sensitive Bay Delta while creating a massive new supply of recycled water.

This advanced infrastructure enables the Harvest Water project, which will deliver 50,000 acre-feet of reclaimed water annually to 16,000 acres of farmland, effectively reducing groundwater pumping and restoring local aquifers by up to 35 feet over the next 15 years.

By leveraging state revolving fund loans and nearly $400 million in grants, the utility has successfully mitigated ratepayer impacts while simultaneously restoring 5,000 acres of riparian habitat and boosting streamflows for Chinook salmon.

These efforts demonstrate a scalable blueprint for agricultural reuse, turning environmental regulatory "sticks" into sustainable "carrots" that support both local economies and resilient ecosystems.

What happens when laws designed to protect water fail — and what legal action does it take to set things right?

For decades, the health of the Chesapeake Bay has struggled because of three major pollution sources: stormwater, wastewater, and agriculture. These pressures send nitrogen, phosphorus, and sediment into streams and rivers that flow into the Bay, where they harm water quality and the environment broadly.

While there have been many solutions implemented and tremendous progress made across the watershed, there are still challenges that sometimes require a legal approach.

In this episode, David Reed of the Chesapeake Legal Alliance shares a look at these three major pollution challenges through the lens of local riverkeepers in Maryland.

The story begins with Gunpowder Riverkeeper Theaux Le Gardeur, who explains how unchecked development and failing stormwater controls allowed sediment to smother vital habitat. Next is Alice Volpitta, the Baltimore Harbor Waterkeeper at Blue Water Baltimore, who shares how two of Maryland’s largest wastewater treatment plants fell into disrepair. Finally, Taylor Swanson of the Assateague Coastal Trust talks about the Eastern Shore, where industrial poultry facilities have created unregulated ammonia pollution.

They each share how legal action was the last line of defense for the Chesapeake Bay and local waterways.
