Tulloch acquired a narrow channel of water in the Central Valley foothills -- a remnant of placer mining operations where prospectors had carved trenches to wash gravel for gold. Miners had moved on, but the water kept flowing, and local farmers recognized something the gold seekers had not: the ditch was more valuable for irrigation than it had ever been for mining. They widened it, and by the early 20th century, that modest channel was watering 6,000 acres of farmland in the Oakdale and South San Joaquin areas. What began as a miner's discard became the seed of a reservoir that today covers 1,260 acres of the Stanislaus River canyon.

Photo credit FASTILY, CC BY-SA 4.0. The Stanislaus River feeds Lake Tulloch with water released from the dams above, and that water stays cold even through the dry heat of a Central Valley summer. The temperature makes Tulloch productive fishing water. Rainbow trout and brown trout thrive in the cooler depths, whil...
