Flow is within the typical range for this time of year (25th–75th percentile, based on 7 years of USGS record).

System Insights

  • Water temperature is 49°F — below 50°F, the threshold associated with cold shock risk for immersion.

  • Real-time flow is running well above current model projections. On-the-ground conditions are outpacing the forecast.

Verify access, permits, and local conditions before entering any waterway.

Glossary & Methodology

Cubic Feet per Second (CFS)

The standard measure for streamflow. One CFS is equal to one cubic foot of water flowing past a specific point in one second (about 7.48 gallons).

Acre-Foot (AF)

The volume of water needed to cover one acre of land to a depth of one foot. One acre-foot is exactly 325,851 gallons.

Snow Water Equivalent (SWE)

The amount of water contained within the snowpack. It can be thought of as the depth of water that would theoretically result if you melted the entire snowpack instantaneously.

Data Sources

Live metrics and historical medians are aggregated directly from the US Geological Survey (USGS), California Data Exchange Center (CDEC), and National Resources Conservation Service (NRCS). Daily flow statistics represent provisional records and are subject to agency revision.
