What Makes Yuba City's Water Unique?
Local geology and source profile
Yuba City, California, the Sutter County seat on the Feather River opposite Marysville in the northern Sacramento Valley — a major orchards and agriculture hub in the northern Sacramento Valley — draws its municipal water supply from the Feather River and local Sacramento Valley groundwater wells via the City of Yuba City Department of Public Works Water Division, treating Feather River water or accessing local alluvial groundwater in Sutter County. Water hardness in Yuba City measures 75.5 mg/L — classified as moderately soft.
Yuba City's soft supply reflects the Feather River's Sierra Nevada–Sacramento Valley origin. The Feather River at Yuba City drains: the northern Sierra Nevada (Plumas and Butte County granite, Paleozoic metasediments of the Feather River Peridotite and Sierra Nevada Foothills metamorphic belt — mixed siliceous and some calcareous formations); and the Sacramento Valley alluvial basin in the lower reaches. The northern Sierra Nevada Feather River watershed contains some Paleozoic calcareous metasediments (Calaveras Complex and related formations) in addition to the more typical Sierra Nevada granodiorite, contributing slightly more dissolved calcium than the purely granitic central Sierra Tuolumne–American River sources. The resulting 75.5 mg/L moderate softness is consistent with the northern Sacramento Valley Feather River corridor.
With hardness at 75.5 mg/L, Yuba City residents enjoy moderately soft water with minimal scale challenges. City of Yuba City Department of Public Works consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Feather River (Yuba River confluence) via the City of Yuba City Department of Public Works Water Division — the Feather River Sierra Nevada–Sacramento Valley confluence drainage and the Sacramento Valley alluvial basin of Sutter County; moderately soft supply at 75.5 mg/L in Sutter County.
