The Alameda Creek watershed has experienced dramatic transitions over the last 200 years. Once a landscape of freely meandering streams, portions of this watershed are now shaped by human engineering.
While providing benefits, such as flood control and clean, reliable water for a growing population, these changes have affected the watershed’s ecosystem and biological diversity. The presence of a healthy habitat close to an engineered channel illustrates the delicate balance between meeting societal needs, and ensuring environmental preservation.
In the early 1800s, transportation began to leave its mark on the watershed. Flat-hulled schooners plied the shallow creek water and Bay, and trains carried people and goods through Niles Canyon.
Not far from the Alameda Creek Watershed Center is the Niles Canyon Transcontinental Railroad, Historic District. Here, in the 1860s, a rail line through Niles Canyon provided the first rail connection from San Francisco Bay, to the rest of the nation. The 1884 Sunol depot still stands today, and visitors can still ride trains along a portion of the First Transcontinental Railroad.
But the railroad's establishment is just one chapter in a broader story of development in the watershed. Travel back to 1839 to the Suñol Adobe, where Spanish immigrant Antonio Suñol established a thriving ranch. Managed by a mayordomo who lived in the adobe, this site was an agricultural hub for cattle and crops.
Under Charles Hadsell, and later the Spring Valley Water Company, the property evolved, serving as a cornerstone in the history of San Francisco’s water supply. Today, the site's long history endures under stewardship of the San Francisco Public Utilities Commission.
As we reflect on the historical shifts at the Suñol Adobe, it is important to acknowledge the Ohlone, stewards of the land for thousands of years.
The Muwekma Ohlone have a rich history that predates the region’s ranches and water companies, by thousands of years. Throughout time, nature has always been integral to their lives. It is reflected in their heritage and ancestral practices. They timed their harvests and festivals to the seasons, and actively managed the land with controlled fires that increased the growth of traditional foods and fiber sources.
Despite periods of colonial disruption and loss, the Ohlone community remains a beacon of resilience. Tribal members work to revitalize their Ohlone languages, cultural traditions, and spiritual practices.
