Farmington (Spill Elev 156.5 Ft)
Farmington is a small unincorporated community in San Joaquin County, California, located at an elevation of 156.5 ft. The area has a long history of agriculture, dating back to the early 20th century when it was a major producer of peaches and apricots. The region is fed by the San Joaquin River, with the area's hydrology being heavily influenced by the river's flow. The river provides irrigation water for agriculture, as well as opportunities for recreation, such as boating and fishing. The area's water supply is also dependent on snowpack in the nearby Sierra Nevada mountains. The melting snowpack provides a significant portion of the water supply for the region's agriculture. Overall, Farmington's location in the San Joaquin Valley makes it an important agricultural hub, with a strong dependence on surface water flow and snowpack.

How often is the report updated?
Storage observations are updated daily by the operating agency. The 15-day weather forecast refreshes throughout the day. Snoflo caches and renders the most recent observation -- check the "as of" timestamp on the storage card.
What does the Hazard hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
