USGS FLOW DATA

Service Advisory

Some services on this site may be temporarily unavailable or behave unexpectedly while we address recently identified cybersecurity vulnerabilities. We apologize for any inconvenience and appreciate your patience while we work to keep your data safe.

Choose a gauge and date range, then click “Show graphs.”

Data source: U.S. Geological Survey (USGS) Water Services — Daily Values (mean) and Daily Statistics. Every measurement the gauge records (streamflow, gage height, water temperature, and any variations) is shown on its own graph. “Lifetime average” is the mean for each calendar day over the gauge’s full period of record. Recent values are provisional and subject to revision. Washington, Oregon and Idaho stream gauges in the Columbia River Basin.

Please Note: Only gauges that are actively collecting flow data in WA/OR/ID are included in this database. Figures come directly from USGS and may be revised; always verify with official sources (WSU is not responsible for use of this data). Individual gauges sometimes go offline for maintenance, equipment failure, ice, or seasonal shutdowns — occasionally for extended periods — so a graph may show gaps or no data until that gauge is back online.
