About this location

Turlock Canyon Near La Grange

The primary flow provider for this gauge is the Turlock River, which is a tributary of the San Joaquin River. There are no significant dams or tributaries associated with this gauge. The hydrology of this area is characterized by distinct seasonal trends, with peak flow occurring in the late winter and early spring due to snowmelt. Interestingly, the gauge has experienced several instances of extreme flooding, including a notable event in 1997 that caused widespread damage in the surrounding area. Overall, the Turlock CN NR La Grange CA streamgauge provides valuable data for researchers and water managers seeking to understand and manage the hydrologic conditions in this region.

Nearby streamflow levels

Cross-check Turlock Canyon Near La Grange's discharge against nearby gauges to spot whether the change here is local or regional.

Regional snowpack

Nearby snowpack data

Snowpack at SNOTEL stations near Turlock Canyon Near La Grange. Spring snowmelt is the dominant driver of streamflow in mountain basins -- a deep snowpack upstream means more runoff later in the season.

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 Turlock Canyon Near La Grange in the Snoflo app

Save this gauge as a favorite, set push alerts when streamflow crosses a threshold (e.g. "alert me when Turlock Canyon Near La Grange crosses 5,000 cfs"), and Snoflo's iOS app will push the moment USGS reports the crossing.

FAQ

About Turlock Canyon Near La Grange

What is the Turlock Canyon Near La Grange flow rate right now?

As of August 2, 2026, Turlock Canyon Near La Grange is flowing at 1,750 cfs. The live value, gage height, and 24-hour trend are shown at the top of this page.

Is the Turlock Canyon Near La Grange running high or low right now?

Check the percent of median figure on this page: above 100% means Turlock Canyon Near La Grange 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 Turlock Canyon Near La Grange come from?

Discharge, gage height, and water temperature come directly from the USGS streamflow gauge 11289500. 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 Turlock Canyon Near La Grange 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.
