2012 Map of Twitchell Dam
USGS Topo · Published 2012About this map
Twitchell Dam and its expansive Twitchell Reservoir anchor this 2012 survey of the water systems northeast of Santa Maria. The landscape is defined by the convergence of major waterways, including the Cuyama River and Sisquoc River, which merge to form the wide bed of the Santa Maria River. This hydrological nexus serves as a critical point for the Santa Maria Valley, where the terrain transitions from the steep slopes of Los Coches Mountain and Cañada De Los Coches to the agricultural flats near Garey. Local landmarks such as Fulger Point and Gates sit among a grid of rural roads like Rancho Tepesquet Rd and Fugler Rd, illustrating the intersection of modern infrastructure with the natural drainage basins of Bradley Canyon and Santa Maria Canyon.
