How could Sacramento County's El Niño preparations affect the Sacramento River?
Increased runoff and flood risk may strain Sacramento River capacity As Sacramento County prepares for a strong El Niño Winter, the risk of winter flooding increases, which could put strain on the Sacramento River. The county has opened three sandbag locations, including the Branch Center, to help residents in unincorporated areas prepare for possible flooding. Since Sacramento is located in a floodplain, the expected heavy rainfall and subsequent runoff would flow into the Sacramento River, potentially exceeding its normal capacity.

Sacramento County opened three sandbag locations to allow residents to prepare for possible winter flooding. These sites are available 24 hours a day for residents in unincorporated areas served by the county’s stormwater utility. The county provides sand and bags, asking people to take no more than 20 bags per visit.

Why it matters
The Sacramento River is a critical waterway for the region, and its capacity is essential for managing water flow and mitigating flood risk. Increased runoff from heavy El Niño-driven rains could place significant strain on the river, potentially increasing the risk of flooding in surrounding areas.
Sacramento County is actively managing this risk by providing public information and resources, such as sandbags, to residents. This preparation reflects the known vulnerability of the county's floodplain status to the predicted climate impacts of El Niño.
