Water context

Stanislaus’s water profile

Modesto and Turlock subbasins are fed by the Tuolumne River through Modesto and Turlock Irrigation Districts, with the Stanislaus River serving Oakdale and South San Joaquin Irrigation Districts on the north end. Pre-1914 surface rights cover most district acreage; groundwater-dependent corners are where elevated bands appear.
