Area History

Location and Natural Setting of Bass Lake

Bass Lake is located about one hour northwest of Fresno and roughly 17 miles from the southern entrance to Yosemite National Park. Surrounded by tall pine trees at an elevation of approximately 3,415 feet, the lake is known for its clear, emerald-colored water and sandy shoreline.

Early History of the Bass Lake Area

More than a century ago, Bass Lake did not exist as it does today. The area was originally a wide meadow bordered by forested hills and mountains.

Indigenous Peoples and Early Exploration

The Chukchansi people lived in the region for thousands of years, followed by the Mono Indians who arrived about 200 years ago. In 1851, members of the Mariposa Battalion passed through the valley shortly after discovering Yosemite Valley. Mistaking Great Blue Herons for Sandhill Cranes, they named the area Crane Valley—a name that endured, as herons still inhabit the region today.

Willow Creek, a tributary of the San Joaquin River, flowed through the valley and later became central to the area’s development.

Development of Crane Valley Reservoir

In 1895, plans were made to harness Willow Creek to produce hydroelectric power for the San Joaquin Valley. The San Joaquin Electric Company was established, and the first earthen dam in Crane Valley was completed in 1901. Supplies and equipment were hauled up the mountain by mule teams, while timber cleared from the future reservoir was transported back down.

Expansion of Hydroelectric Infrastructure

The San Joaquin Light & Power Corporation was formed in 1902, acquiring both the electric company and later the operations of a competing gas company. The dam was expanded in 1905, and the current dam—standing 145 feet tall—was completed in 1910.

How Bass Lake Got Its Name

Originally known as Crane Valley Reservoir, the lake was later renamed Bass Lake after a nearby lumber operation polluted the water and eliminated the fish population. As part of the cleanup, the company was required to restock the lake, choosing bass as the replacement species, which led to its new name.

Bass Lake Today

Today, Bass Lake is owned and operated by Pacific Gas and Electric Company. Its waters continue to support hydroelectric power generation, Central Valley irrigation, and a wide range of recreational activities. Classified as a warm-water lake, summer temperatures often approach 80 degrees, making it a popular destination for boating, swimming, and fishing.
