The communities that vanished beneath Camanche Reservoir had their roots in the Gold Rush. Prospectors settled along the Mokelumne River in the 1850s, establishing camps at Poverty Bar, Lancha Plana, and a cluster of other settlements in what is now western Calaveras County. As the placer deposits thinned, most camps emptied. The largest surviving town was named Camanche by settlers from Iowa, borrowing the name from their hometown -- which had itself misspelled the name of the Comanche people. By the time the East Bay Municipal Utility District arrived in the early 1960s with plans for a dam, Camanche had dwindled to perhaps 40 or 50 families. A local newspaper captured the mood in 1964: "Camanche will inundate many memories." The families relocated, the dam went up, and the rising water erased what a century of decline had not.

California's multi-year drought from 2011 to 2015 tested Camanche Reservoir as severely as anything since its creation. By August 2015, the reservoir had dropped to its lowest level ever -- just 81,940 acre-feet, roughly 19.6 percent of maximum capacity. The shoreline retreated dramatically, exposing banks that had been underwater for decades. Then the rains returned. By April 2016, water levels had climbed back to 240,340 acre-feet. Through the 2024 storm season, Lake Camanche remained above historical levels, part of a statewide reprieve from drought that forecasters expected to hold through 2026. The cycle exposed both the reservoir's vulnerability to California's increasingly erratic climate and its resilience when the weather cooperates.

When dams blocked the Mokelumne River, the Chinook salmon and steelhead trout that had spawned in the Sierra foothills for millennia lost access to their ancestral grounds. The Mokelumne River Hatchery, built in 1963 just downstream of the dam, was California's attempt to compensate. The facility raises both species, releasing juveniles to maintain populations that can no longer reproduce naturally in sufficient numbers. A 2002 remodeling enlarged the rearing space to improve fish health and survival rates, and the investment paid off: returning salmon increased by 3,028 during the period from 1998 to 2003. The hatchery is an acknowledgment that the dam solved one set of problems -- flooding, water supply -- while creating another that requires permanent, active management.

The landscape surrounding Camanche Reservoir is California oak woodland, a community dominated by valley oak and blue oak that grow in a characteristically spread-out pattern rather than dense forest. The understory is a mix of native grasses, herbs, and shrubs, along with introduced grass species that have colonized much of California's foothill country. The Mediterranean climate -- hot, dry summers and cool, mild winters with most rainfall concentrated in the winter months -- shapes everything here. Deer frequent the reservoir's edges, and small mammals are abundant enough to support predators: bobcats live near the lake but are rarely spotted. Birdwatchers come for the Great Egrets, woodpeckers, Turkey Vultures, and the variety of songbirds that thrive in the oak canopy. The reservoir itself holds bass, trout, crappie, and catfish, though the California Office of Environmental Health Hazard Assessment has issued an advisory about mercury levels in fish caught here.

At full pool, Camanche Reservoir stretches across 56 miles of shoreline, and the recreation infrastructure built around it is substantial. Five campground areas -- North Shore, South Shore, Boat-in, Group, and Equestrian -- offer more than 500 campsites and 200 RV locations, available year-round. Hiking and equestrian trails wind through rolling hills and oak groves along both shores. Eight-lane boat launches serve each side of the lake, and every vessel entering the reservoir faces mandatory inspection to prevent the spread of invasive quagga mussels. From a few thousand feet of altitude, the reservoir reads as a sprawling blue irregular shape set into golden-brown hills, with Pardee Reservoir visible upstream and New Hogan Lake to the southeast. Highway 88 passes nearby, connecting the lake to Grinding Rock State Historic Park in the Sierra foothills -- a reminder that this landscape has been drawing people, for gold or for recreation, for nearly two centuries.
