Three Towns, One Valley
Lodi, Woodbridge & Galt: History, Water, and the Ties That Bind
Summary
Lodi, Woodbridge, and Galt sit within eight miles of each other along California's Highway 99 corridor, sharing Gold Rush origins, railroad-era founding stories, and the same critically overdrafted aquifer systems. Today they cooperate through wine industry branding (the Lodi AVA), shared transportation, flood response, and overlapping education and healthcare — yet they compete for housing growth, retail dollars, and commercial investment across a Sacramento/San Joaquin county boundary that divides their governance. The water beneath them — managed by two separate groundwater authorities overseeing 23 combined agencies — may be the most consequential shared resource determining all three futures.
Part 1: Parallel Origins — From Miwok Country to Railroad Towns
Before the Settlers
Long before any of these towns existed, the Plains Miwok people — including the Cosumne, Sonolomne, and Unizumne tribes — lived and hunted across this stretch of the Central Valley. The Mokelumne River, whose name derives from a Miwok word meaning "the place of the fish net," was central to their way of life. The land was flat, fertile, and threaded with waterways that would later attract an entirely different kind of settler.
Woodbridge: The First to Arrive (1852)
Woodbridge is the oldest of the three communities. In 1852, Jeremiah H. Woods and Alexander McQueen established a ferry crossing on the Mokelumne River, creating a vital link on the road between Stockton and Sacramento. Woods soon replaced the ferry with a toll bridge — charging $1 for a wagon with a pair of animals — and the settlement became known as "Woods' Bridge."
Woods had grand ambitions. He envisioned Woodbridge growing larger than Stockton and even lobbied to carve out a new "Mokelumne County" with Woodbridge as its seat. For a time, the settlement's position on the only major road between Sacramento and Stockton gave it genuine economic importance. But the railroad would redirect that importance elsewhere.
Galt and Liberty: Gold Rush Offspring (1850s–1869)
In 1850, a group of farmers settled along Dry Creek, about eight miles north of the future site of Lodi, to grow beef and dairy products for the mining camps. Two years later, Chism Cooper Fuggitt founded a settlement he named Liberty — after his hometown in Missouri — on high ground just south of Dry Creek. Liberty served as a stopping place for freight haulers on the route between San Francisco and the Mother Lode.
The pivotal moment came in 1869 when Dr. Obed Harvey — a physician, former state senator, and shrewd operator — used his political connections to bring the Central Pacific Railroad through the area. His friend John McFarland, a wealthy rancher who had come to California seeking gold but made his fortune selling water for mining purposes and later farming wheat, suggested naming the new town after his hometown of Galt, Ontario, Canada. For a time, Galt was the end of the line on the railroad, giving it outsized importance as a shipping point to Sacramento.
Lodi: Born of the Railroad (1869)
That same year — 1869 — the Central Pacific continued south. Pioneer settlers Ezekiel Lawrence, Reuben Wardrobe, A.C. Ayers, and John Magley offered 160 acres to the railroad as incentive to build a station. The railroad accepted, received a 12-acre reserve in the middle of town, and surveyors began laying out streets. Initially called Mokelumne Station, the town was renamed Lodi in 1874, likely after the Italian city where Napoleon won a famous victory in 1796.
The railroad's decision to bypass Woodbridge in 1867 was a turning point. Woodbridge lost its economic momentum and pivoted to become an educational center, opening the Woodbridge Seminary and San Joaquin Valley College in 1879. Lodi boomed as a shipping center and was officially incorporated in 1906. Galt, sitting on the same rail line but in Sacramento County, developed at its own pace and incorporated in 1946.

Part 2: Highways, Wine, and Identity
The Lincoln Highway Showdown
In 1913, the Lincoln Highway — America's first transcontinental auto route — was being routed from Sacramento to Stockton. The highway ran south from Galt along Lower Sacramento Road through Woodbridge, bypassing Lodi entirely. "If Lodi is not on the direct highway, it means oblivion as far as this traffic is concerned," declared M.O. Holt, president of the Merchants Association. Lodi businessmen went door-to-door for petition signatures, but the highway went through Woodbridge, not Lodi.
Lodi merchants responded by erecting an enormous sign at the junction of Lower Sacramento Road and Turner Road, directing tourists to "veer away from the Lincoln Highway" and take the scenic route through Lodi. By the 1920s the highway was rerouted, and by the 1950s the modern Sacramento–Lodi Freeway (Highway 99) connected all three communities along the same corridor.
The Wine Connection
If any single industry binds these three communities, it is wine. The Lodi American Viticultural Area (AVA), established in 1986, spans portions of both Sacramento and San Joaquin counties and encompasses vineyards in all three communities. As of 2024, Lodi-area farms produce roughly 20% of all California wine.
The first cooperative winery in the region — and likely the oldest in California — was the Woodbridge Vineyard Association, established in 1905 on the south bank of the Mokelumne River. Starting with 39 grower-members, it crushed 3,138 tons in its first year. The cooperative model defined Lodi-area winemaking for most of the 20th century.
In 1979, Robert Mondavi purchased an Acampo facility and established Woodbridge Winery (now Woodbridge by Robert Mondavi), which became one of the largest table wine labels in the nation and catalyzed Lodi's shift from bulk commodity grape growing to quality-focused viticulture. The Lodi Winegrape Commission today promotes the entire "Lodi-Woodbridge region" and developed the pioneering LODI RULES sustainability certification program, with certified vineyards stretching from Galt through Woodbridge and across the broader Lodi area.
Seven Sub-Appellations Within Lodi AVA (est. 2006)
Alta Mesa · Borden Ranch · Clements Hills · Cosumnes River · Jahant · Mokelumne River · Sloughhouse — These sub-AVAs recognize distinct terroir differences within the shared wine country that spans both Sacramento and San Joaquin counties.
Wineries now operate in all three communities. Barsetti Vineyards maintains a tasting room in downtown Galt, Oak Farm Vineyards near Galt has become a destination attraction, and scores of family wineries dot the landscape from Woodbridge through Acampo and beyond. The "Lodi" brand benefits growers regardless of which side of the county line their vines are planted.
Part 3: Where They Cooperate
Wine Industry and Agricultural Economy
The Lodi Winegrape Commission serves growers across both counties. The LODI RULES program has expanded to over 70,000 certified winegrape acres statewide, built on what the Commission calls a "let's do this right for the whole area" philosophy. The recently formed Lodi Winery Tourism District, approved in November 2025 with over 72% support, will further formalize cross-community cooperation.
Transportation and Infrastructure
Highway 99 is the arterial lifeline connecting all three communities. Lodi's Amtrak station, opened in 2002, provides San Joaquin Valley rail connections serving residents of Woodbridge and Galt alike. South County Transit and San Joaquin Regional Transit District provide bus service across the corridor. The Lincoln Highway, US Route 99, and today's freeway represent a shared transportation spine stretching back over a century.
Flood Control and Emergency Response
The Mokelumne River and Dry Creek have historically threatened all three communities. The November 1950 flood evacuated 1,000 people from both Woodbridge and Lodi simultaneously, and flood events have periodically forced cooperative sandbagging efforts across community lines. Flood management on the Mokelumne requires coordination between San Joaquin County, Sacramento County, and the water districts spanning both.
Healthcare and Education
Lodi Memorial Hospital (now Adventist Health Lodi Memorial), founded in 1952 through community fundraising, serves patients from Woodbridge and southern Galt. Lodi Unified School District spans 350 square miles and serves over 27,000 students in Lodi, Woodbridge, and surrounding areas. While Galt has its own school districts, Lodi Unified boundaries historically encompassed areas later transferred to Galt — reflecting the organic connections between these communities.
Part 4: Where They Compete
Housing and Growth
The most visible competition between Lodi and Galt is for Sacramento-bound commuters seeking affordable housing. Both cities offer lower home prices than Sacramento or Elk Grove, and both are expanding aggressively.
Galt has planned over 800 new homes across three annexation projects, including the 429-unit Simmerhorn Ranch development. Lodi has pursued expansion through the Southwest Gateway (1,700 homes along Lower Sacramento Road) and new neighborhoods by FCB Homes, while maintaining a 2% annual growth cap. Lodi's Eastside Vision proposes technology and light manufacturing — but the city's own planning documents acknowledge this puts it in direct competition with established Sacramento-region technology corridors.
The county boundary sharpens this competition. Galt falls under Sacramento County's framework and SACOG housing allocations, while Lodi answers to San Joaquin County and the San Joaquin Council of Governments — different regulatory environments, fee structures, and developer incentive packages creating jurisdictional arbitrage for homebuilders.
Figure 2: Planned housing development comparison
Commercial Retail and Governance
Lodi's Kettleman Lane commercial corridor and downtown shopping district serve as the dominant regional retail center. Galt's commercial development has been more modest, though its famous Galt Market — an open-air market every Tuesday and Wednesday — draws bargain hunters from across the region. As Galt grows, commercial development will increasingly compete with Lodi for retail dollars.
The fundamental competitive tension is governance and identity. Galt is a Sacramento County city, politically oriented toward the state capital. Lodi is a San Joaquin County city, historically considered the "Queen City" of its county. Woodbridge, unincorporated, is culturally part of Lodi but retains distinct identity as the oldest settlement in the area.

Part 5: The Water That Connects (and Divides) Them
Water is the most consequential shared resource among these communities, and the most complex. Understanding the picture requires looking at both surface water and groundwater, and at the patchwork of agencies that manage each.
The Mokelumne River: Lifeblood of the Region
The Mokelumne River flows between Lodi and Woodbridge, forming the historic and hydrological spine of the region. The Woodbridge Diversion Dam, operated by the Woodbridge Irrigation District (WID), impounds the river to create Lodi Lake — one of Lodi's most beloved recreational assets.
WID was organized in 1924 and holds some of the oldest water rights on the Mokelumne — pre-1914 and post-1914 appropriative rights allowing diversion of 300 cubic feet per second from February through October, with additional capacity during other months. The district's 63-square-mile service area covers Woodbridge, Thornton, and portions of Lodi and Stockton, delivering water to approximately 13,000 acres of farmland.
Landmark Water Agreement: WID & Lodi (2003)
WID entered into a 40-year, $1.2 million per year contract to sell 6,000 acre-feet per year of Mokelumne River water to Lodi for municipal use. Until that point, every drop of Lodi's drinking water came from underground wells. When the Lodi Surface Water Treatment Plant opened in 2012, roughly 50% of the city's supply shifted to treated Mokelumne River water — fundamentally changing the city's water profile.
The East Bay Municipal Utility District (EBMUD), serving 1.4 million customers in Alameda and Contra Costa counties, is the other major holder of lower Mokelumne River water rights. EBMUD's involvement in the region extends to innovative groundwater banking projects that directly affect the Lodi-Woodbridge area.

Two Aquifers, Two Challenges
While Lodi and Woodbridge share the Mokelumne River, the groundwater picture is more complicated. These communities overlie two distinct but related groundwater subbasins separated by a boundary that roughly follows the Mokelumne River and the San Joaquin County line.
The Eastern San Joaquin Subbasin
Lodi and Woodbridge sit atop the Eastern San Joaquin Subbasin, extending from the Mokelumne River on the north to the Stanislaus River on the south — approximately 1,195 square miles. The California Department of Water Resources has classified it as a "high priority critically over-drafted basin." Over the past decade, the basin has pumped out roughly 600,000 acre-feet more water than has been recharged, with current annual overdraft of approximately 30,000 acre-feet. Consequences include saltwater intrusion, land subsidence, well failures, and water quality degradation.
The Eastern San Joaquin Groundwater Authority (ESJGWA), formed in 2017, coordinates 16 Groundwater Sustainability Agencies (GSAs) including the City of Lodi, Woodbridge Irrigation District, and North San Joaquin Water Conservation District. Its Groundwater Sustainability Plan aims to achieve basin sustainability by 2040.
The Cosumnes Subbasin
Galt sits atop the Cosumnes Subbasin — bounded by the Cosumnes River on the north and west, the San Joaquin County line and Mokelumne River on the south, and bedrock on the east. Historical depletion averages approximately 11,600 acre-feet per year, and the subbasin needs to replace roughly 20,000 acre-feet annually to reach sustainability.
Seven GSAs collaborate under the Cosumnes Groundwater Authority (CGA): the City of Galt, Galt Irrigation District (founded 1953), Clay Water District, Omochumne-Hartnell Water District, Sacramento County, Sloughhouse Resource Conservation District, and the Amador County Groundwater Management Authority.
Figure 4: Groundwater overdraft — Eastern San Joaquin vs. Cosumnes subbasins
The Basin Boundary: A Critical Jurisdictional Line
The boundary between the Eastern San Joaquin and Cosumnes subbasins is not just a geological feature — it's a governance line. In 2016, the North San Joaquin Water Conservation District requested a boundary modification because its operations span both subbasins, and managing water supply across two different Groundwater Sustainability Plan frameworks placed an enormous burden on this small district. The City of Galt, Galt Irrigation District, Clay Water District, and the Southeast Sacramento County Agricultural Water Authority all participated in discussions about this boundary change — illustrating how the water these communities share does not respect county lines or municipal boundaries.
The DREAM Project: A Model for Regional Cooperation
DREAM: Demonstration Recharge, Extraction & Aquifer Management
Partners: North San Joaquin Water Conservation District, San Joaquin County, EBMUD, Eastern Water Alliance
How it works: EBMUD provides up to 1,000 acre-feet of Mokelumne River surface water in wet years to irrigate crops east of Lodi, reducing farmer groundwater pumping. In exchange, EBMUD receives a credit to withdraw up to half that amount during dry years.
Result: Net gain of water in the aquifer, farmers get irrigation water, and East Bay communities get greater drought resilience.
Status: Pilot phase expected to complete March 2026. Partners are discussing a larger-scale groundwater banking program.

Part 6: Looking Ahead
The futures of Lodi, Woodbridge, and Galt are bound together by geography, water, and economics in ways that no county boundary can fully separate.
Water sustainability is the defining challenge. Both the Eastern San Joaquin and Cosumnes subbasins are critically overdrafted. If local agencies cannot achieve sustainability by 2040, California has the authority to step in and manage the basins directly — with higher costs, more restrictions, and potential well metering. The stakes are enormous for farmers, cities, and residents across all three communities.
Growth will intensify competition. Both Lodi and Galt are actively annexing land and building new housing. As Sacramento's commuter shed extends further south, both cities will compete for families, retail, and commercial investment. Woodbridge will face pressure from Lodi's expansion on one side and the desire to maintain its rural character on the other.
The wine industry will continue to unite. The Lodi appellation brand transcends municipal and county lines. With the new Lodi Winery Tourism District and continued growth of LODI RULES, wine will remain the cultural thread stitching these communities together most visibly.
Climate change raises the stakes. Longer droughts increase groundwater pumping. Intense rain events test shared flood infrastructure. Changing growing conditions will reshape the agricultural economy that defines the region's identity.
Conclusion
Lodi, Woodbridge, and Galt were born in the same era, from the same Gold Rush energy and railroad ambition. Jeremiah Woods built his bridge, the Central Pacific laid its tracks, and the settlers who gathered along the Mokelumne River and Dry Creek built communities that have been neighbors, rivals, and partners ever since.
Today, the old rivalries — over highway routes and railroad stations — have faded into colorful history. In their place are more consequential shared challenges: managing a critically overdrafted aquifer, balancing growth with agricultural preservation, and maintaining the small-town character that draws people to all three communities.
The water beneath their feet doesn't know about county lines. The vines planted in their shared soils don't care whether the label says Lodi, Woodbridge, or Galt. And the families who live in these communities — many of whom work, shop, and worship across all three — understand intuitively what the history makes clear: these are three towns, but one valley.
