Geography
Two streams drain the area, the Salt and Elk Creeks. The Salt Creek flows north in the area, then bends east, and is joined by Elk Creek. Both streams join Sand Creek a half mile northeast of the town and flow in a northeast direction. Salt Creek is subject to periodic flooding during heavy rainfall.
The town sank between 2008 and 2017 according to a report issued by the California Department of Water Resources in coordination with 19 local and state agencies. A study that analyzed over 300 sites across the Sacramento Valley found that this area had sunk due to groundwater-related subsidence more than any other area in the study. Subsidence occurred as water was removed from the underground aquifers and the surrounding soil collapsed upon itself.
