2021 Map of Twitchell Dam

USGS Topo · Published 2021

About this map

The Cuyama River and Sisquoc River converge to form the Santa Maria River in this modern-era study of the border between Santa Barbara and San Luis Obispo counties. The geography is dominated by the Twitchell Reservoir, which regulates the flow from the mountains to the northeast into the fertile Santa Maria Valley. The map details the transition from the steep, ridged terrain of the Sierra Madre Mountains and Los Coches Mtn down to the low-lying agricultural flats and canyons south of the riverbed.
