Santa Ynez River A 13th St Bridge A Vafb Near Lompoc
The Santa Ynez River A 13th St Bridge A Vafb Near Lompoc streamgauge is part of the USGS streamflow monitoring network and provides continuous discharge data for California. The gauge measures water flowing past a fixed point on the river, with readings updated every 15 minutes.
Streamflow at this site varies seasonally with snowmelt runoff, rainfall, upstream reservoir operations, and groundwater contributions. The peak-flow season typically corresponds to spring snowmelt in mountain basins, with secondary peaks from intense rainfall events.

River levels & flood safety
- Read the level before you go
- A river that's runnable at one flow can be deadly at another. Check current discharge and gage height — like the values shown above — against the flood-stage thresholds, and remember levels can spike fast after rain or a dam release.
- Respect cold water
- Snowmelt rivers run cold even in summer. Sudden immersion triggers cold-water shock and saps strength within minutes. Wear a PFD, dress for the water temperature (not the air), and never wade or paddle alone.
- Watch for swiftwater hazards
- Strainers (downed trees), undercut rocks, and low-head dams are the deadliest features on moving water. High, fast, muddy water hides them. If in doubt, scout from shore and portage.
- Mind flash floods & releases
- Narrow canyons can flood from a storm miles upstream, and dam-controlled reaches can rise without warning. Know the forecast, the release schedule, and your exit before you launch.
Track Santa Ynez River A 13th St Bridge A Vafb Near Lompoc in the Snoflo app
Save this gauge as a favorite, set push alerts when streamflow crosses a threshold (e.g. "alert me when Santa Ynez River A 13th St Bridge A Vafb Near Lompoc crosses 5,000 cfs"), and Snoflo's iOS app will push the moment USGS reports the crossing.
About Santa Ynez River A 13th St Bridge A Vafb Near Lompoc
What is the Santa Ynez River A 13th St Bridge A Vafb Near Lompoc flow rate right now?
As of September 30, 2026, Santa Ynez River A 13th St Bridge A Vafb Near Lompoc is flowing at 0 cfs. The live value, gage height, and 24-hour trend are shown at the top of this page.
Is the Santa Ynez River A 13th St Bridge A Vafb Near Lompoc running high or low right now?
Check the percent of median figure on this page: above 100% means Santa Ynez River A 13th St Bridge A Vafb Near Lompoc is running higher than normal for the date, below 100% means lower. The 24-hour trend shows whether it's rising or falling.
Where does the streamflow data for Santa Ynez River A 13th St Bridge A Vafb Near Lompoc come from?
Discharge, gage height, and water temperature come directly from the USGS streamflow gauge 11135250. Snoflo refreshes the time series throughout the day. Forecasts come from the NOAA / yr.no feed Snoflo's iOS app uses.
How often is the report updated?
USGS gauges report continuously (typically every 15 minutes). Snoflo pulls fresh values throughout the day — look for the "as of" timestamp on the streamflow hero card.
What's the difference between discharge and gage height?
Discharge (cubic feet per second, or cfs) is the volume of water flowing past the gauge each second. Gage height is how high the water sits at the gauge (feet). They're related by a rating curve specific to each gauge — higher water means more flow, but the exact ratio depends on channel shape.
How is "percent of median" calculated?
Today's discharge is compared to the historical median discharge on this calendar day across the gauge's full record. 100% = right on median; 200% = a very high year; 30% = a drought-level low.
What are flood stages, and is this river safe right now?
Flood stages are NWS-defined gage-height thresholds — Action, Minor, Moderate, Major — marking when nearby roads or floodplains start to be affected. "Safe" depends on your activity and skill: a level that's a fun paddle for an expert can be lethal for a wader. Always check the current level against the thresholds above and the safety links, and when in doubt, stay off the water.
Can I get alerts when Santa Ynez River A 13th St Bridge A Vafb Near Lompoc rises?
Yes — flow alerts are managed in the Snoflo iOS app. Favorite this gauge, set a streamflow threshold (e.g. "alert me when discharge crosses 5,000 cfs"), and you'll get a push the moment USGS reports the crossing.
