2021 Map of New Melones Dam

About this map

The Stanislaus River corridor defines the geography of this California region, where the modern landscape is dominated by the sprawling waters of New Melones Lake and the Tulloch Reservoir. The map illustrates the rugged transition from the high ridges of Big Seven Ridge and Bostick Mtn down into the submerged canyons. While residential developments like Tulloch Lake Estates and Conner Estates mark recent growth, the map preserves the nomenclature of the gold era through features such as Bostick Bar and Vermont Bar along the river's original course. Significant terrain landmarks including Table Mtn, Peoria Mtn, and the distinctive Negro Jack Point provide a clear view of the complex topography surrounding Iron Canyon. Historical land use is suggested by names like Bowie Flat and Peoria Basin, which contrast with the steep canyons and gulches that feed into the reservoirs.
