About The River

The Tuolumne River below the La Grange Dam is rich with diverse ecology and a mélange of colorful history. Starting as a calm, unassuming body of water, it builds momentum to swell into a raging torrent during peak seasons. The La Grange Dam, built in 1893, added a dramatic twist in its narrative swing, altering the river’s flow.

  • The early Native American tribes used the river for sustenance, attributing it deep spiritual significance.
  • In the 1849 gold rush, La Grange became an exciting hive of activity. The river was exploited for placer mining, a method involving washing soil and gravel to extract gold.
  • The construction of the La Grange Dam was aimed at facilitating irrigation and supporting agriculture. Its subsequent operation for over a century bears testimony to its engineering prowess.

Today, the Tuolumne River — Blw La Grange Dam gives us a glimpse into the complex relationship between mankind and nature, a history lesson underscored by waves.
