A watershed-related issue examined by the ENVS 560/L Watershed Systems class at CSUMB.

Summary

Los Osos, on the central coast of CA,

Location

Los Osos is an unincorporated community in San Luis Obispo County, CA with a population of 14,276 in 2010 [1]. The town's water supply is locally sourced from the Los Osos Groundwater Basin, which is managed by three water providers: Los Osos Community Services District (LOCSD), Golden State Water Company, and S&T Mutual Water Company [2].

Los Osos Groundwater Basin

The Los Osos Groundwater Basin provides residential, commercial and agricultural water for Los Osos. The basin covers about 10 square miles with an approximate maximum depth of 1,000 feet. The basin is underlain by unconsolidated deposits such as alluvium, ancient sand dunes and mostly impermeable Paso Robles Formation and basement Franciscan Complex [3]. Water is extracted from the multi-level Paso Robles Formation, underneath which lies the Franciscan Complex. The Franciscan Complex does not bear water and confines the basin to the west [4].
