Most dams announce themselves - massive concrete arcs visible for miles, reservoirs gleaming behind them. La Grange Dam does the opposite. Sitting just two miles downstream of the New Don Pedro Dam and its 13,000-acre reservoir, La Grange is the workhorse nobody notices: a 131-foot masonry-gravity diversion dam completed in 1893, back when the Turlock and Modesto Irrigation Districts were still convincing skeptical farmers that irrigation could transform the dry San Joaquin Valley into productive farmland. Those farmers were convinced. Today, La Grange Dam diverts an average of 885,000 acre-feet of Tuolumne River water each year into a canal system that irrigates some of the most productive agricultural land in the world. It also feeds San Francisco's drinking water supply, generates hydroelectric power, and maintains the river flows that keep salmon and steelhead alive downstream. For a structure most people drive past without a second glance, it does an extraordinary amount of work.

La Grange Dam was a feat of nineteenth-century engineering ambition. When the Turlock and Modesto Irrigation Districts began construction, large-scale irrigation in California's Central Valley was still more theory than practice. The dam rose as a masonry-gravity structure - ston...

Every year, nearly 900,000 acre-feet of water reaches La Grange Dam from Don Pedro Reservoir upstream, and the dam splits it with bureaucratic precision. About 575,000 acre-feet flows through the Turlock Irrigation District's canal on the south bank to Turlock Lake. Another 310,0...

Tucked against the east bank of the Tuolumne, a small hydroelectric power station draws water diverted by the dam to generate four megawatts of electricity. It is modest output by modern standards - enough to power roughly 3,000 homes - but the plant, operated by the Turlock Irri...

California's water wars are famous for their drama - courtroom battles, political campaigns, entire towns swallowed by reservoir construction. La Grange Dam has largely avoided the spotlight. It sits in the shadow of the much larger New Don Pedro Dam upstream, which impounds the ...
