Total streamflow across the Truckee River was last observed at 11,286 cfs, and is expected to yield approximately 22,386 acre-ft of water today; about 70% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 16,156 cfs, with recent peaks last observed on 2017-05-06 when daily discharge volume was observed at 62,940 cfs.

Maximum discharge along the river is currently at the Truckee River Nr Tracy reporting a streamflow rate of 1,280 cfs. This is also the highest stage along the Truckee River, with a gauge stage of 9.01 ft at this location. This river is monitored from 13 different streamgauging stations along the Truckee River, the highest being situated at an altitude of 6,235 ft, the Truckee R A Tahoe City Ca.

Profile

Streamflow elevation profile

Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

About this river

Truckee River

The Truckee River is a 121-mile-long river located in California and Nevada. It begins at Lake Tahoe and flows through the Sierra Nevada Mountains, eventually ending in Pyramid Lake. The river has a rich history, with Native American tribes, such as the Paiute and Washoe, utilizing the area for fishing and hunting. Today, the Truckee River serves as a crucial source of water for agricultural irrigation and drinking water for the surrounding communities. There are several reservoirs and dams along the river, including the Boca Reservoir and the Stampede Reservoir, which regulate water flow and provide hydroelectric power. In addition to its practical uses, the Truckee River is also a popular destination for recreational activities, such as fishing, kayaking, and camping.

FAQ

About the Truckee River

Where does the data for the Truckee River come from?

Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.

How is "percent of normal" calculated?

Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).

Why are some gauges showing very different flows?

Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.

What's the elevation profile chart showing?

Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.

Can I get alerts when a specific gauge crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
