Graphs for All Rivers

‚ÄčNote: Flood prediction is not an exact science. Although gauge readings and historical data are excellent forecasting tools, please remember that rivers continually change. There are also local factors that can contribute to flooding such as stream and creek discharge into a river, snowmelt and damming caused by fallen trees and other debris. Therefore, during flood situations floodplain residents should not rely solely on gauge readings and historical flood levels, but should keep an eye on the river and stay tuned to local media reports.

During flood situations, Thurston County Emergency Management posts additional information and media releases on its emergency information page.
