For over 70 years, a section of California’s San Joaquin River was cut off from the land it once naturally fed.

it → cut → land
Old levees, not built to hold back a river but to hold cattle, had quietly changed the landscape.

Then in 2026 crews started to undo that history.

Great Valley Grasslands State Park, outside Merced, was the scene of a celebration on June 11, as dozens of scientists, Tribal leaders, state officials, conservationists and community members gathered to mark the completion of a restoration project that took more than 15 years to bring to fruition.
asserted
that → gather → fruition
The Grasslands Floodplain Restoration Project, finished in February 2026, has reconnected the San Joaquin River to over 220 acres of historic floodplain habitat.
asserted
Project → finish → habitat
The project is returning the river to its natural overflow across the grasslands, by breaching sections of old levees.
asserted
project → return → levees
It’s a remarkable environmental turnaround — and one that began with an unlikely gift from a California dairy farmer and cheesemaker.

A river at last finds its way home

According to the American Rivers website news report, the June gathering was more than a ceremonial occasion.
uncertain
gathering → accord → occasion
After speeches by state officials, tribal representatives and conservation leaders, attendees walked along the San Joaquin River to the newly breached levee.
asserted
attendees → walk → levee
A red ribbon was draped across the new channel.
asserted
ribbon → drape → channel
It is reported that American Rivers led the project’s implementation, in partnership with California State Parks, River Partners and Flow West.

Rivers → report → Parks
The event was one of five spotlight events highlighting conservation efforts across the state as part of California State Parks Week.
asserted
event → highlight → Week
That’s a relay, a passing of the torch from one generation to the next to care for the land,” said Ann Willis, California regional director for American Rivers.

Why we care about floodplains
The report states that floodplains are much more than a coincidence of flooding.
asserted
floodplains → care → flooding
They are some of the most productive ecosystems on earth, providing habitat for plants and animals and performing important functions for people.
asserted
They → provide → people
When rivers can flow over their natural floodplains, water slows, filters through soil and helps recharge underground aquifers.
asserted
water → flow → aquifers
The newly reconnected floodplain along the San Joaquin River is expected to provide a variety of benefits.
asserted
floodplain → reconnecte → benefits
Also, seasonal flooding can help reduce invasive plants that prefer drier conditions and improve conditions for native grasses and wetland plants.
asserted
that → help → grasses
These plants also provide food and shelter for wildlife.
asserted
plants → provide → wildlife
It is also believed to benefit threatened and endangered fish species, including Chinook salmon.
asserted
It → believe → salmon
And, floodplain areas can offer juvenile salmon relatively sheltered waters and access to food during a critical stage of their development.
asserted
areas → offer → development
A home for wildlife and vernal pools
As per the report, seasonal flooding can also create vernal pools, temporary wetlands that form during wet periods and dry up as conditions become drier.
asserted
conditions → create → periods
Their lives rely on seasonal patterns of water and soil that have been disturbed in many areas of California.
asserted
that → rely → California
So, restoring those rhythms is more than just restoring water to the land.
asserted
restoring → restore → land
It is about restoring a connected ecosystem in which water, plants, fish and wildlife can respond to seasonal cycles once more.
asserted
water → restore → cycles
An improbable beginning: A dairy farm
If we go by the news report by American Rivers, Great Valley Grasslands State Park has a story with a peculiar beginning.
asserted
Park → go → beginning
Joseph Gallo was a former dairy farmer who built a successful cheese business.
asserted
who → build → business
In 1982, he donated thousands of acres of Central Valley grasslands to the U.S. Fish and Wildlife Service and the state of California.
asserted
he → donate → California
He requested that the land be preserved as wildlife refuges and parks.
asserted
land → request → refuges
Today, Great Valley Grasslands State Park covers nearly 2,826 acres south of Modesto and west of Merced.
asserted
Park → cover → Merced
It includes one of the largest remaining areas of native grassland in California.
asserted
It → include → California
When Gallo donated the property, old levees, built in the 1950s, still crossed the grasslands.
asserted
levees → donate → grasslands
They were not intended to control the San Joaquin River.
asserted
They → intend → River
Instead, they served as a means of corralling cattle within the dairy operation.
asserted
they → serve → operation
A 15-year effort to reverse the past
More than 15 years ago, American Rivers began working with California State Parks, River Partners and other agencies, nonprofit organizations and private partners to learn how to restore the park’s native grasslands and reconnect the river to its floodplain.
asserted
Rivers → reverse → floodplain
Permitting problems and the realities of working in an area that nature designed to flood have delayed the project.
asserted
nature → permit → project
Weather and flooding could halt construction for months, making work impossible.
uncertain
work → halt → months
Some of the State Parks staff and engineers were involved in the project for over 15 years.
asserted
Some → involve → years
Funding eventually came from a number of sources, including California Department of Fish and Wildlife funding through Propositions 1 and 68, California State Parks’ Cannabis Watershed Protection Program and support from Cox Enterprises.

Funding → come → Enterprises
