Total streamflow across the Klamath River was last observed at 15,170 cfs, and is expected to yield approximately 30,089 acre-ft of water today; about 56% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 26,877 cfs, with recent peaks last observed on 2015-02-08 when daily discharge volume was observed at 257,164 cfs.

Maximum discharge along the river is currently at the Klamath R Nr Klamath Ca reporting a streamflow rate of 5,970 cfs. This is also the highest stage along the Klamath River, with a gauge stage of 9.56 ft at this location. This river is monitored from 6 different streamgauging stations along the Klamath River, the highest being situated at an altitude of 3,967 ft, the Klamath River At Keno.

Maximum streamflow discharge by year

The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

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

Klamath River

The Klamath River runs for 257 miles through southern Oregon and northern California, originating in the Cascade Range and emptying into the Pacific Ocean. It has a long history of use by Native American tribes, and later became a hub for the logging and fishing industries. The river's hydrology has been greatly altered by the construction of several dams, including the Iron Gate Dam and Copco Dam, which have impacted salmon populations and water quality. The Klamath Basin also supports agricultural activities, with irrigation districts drawing water from the river to irrigate crops such as alfalfa and potatoes. Recreational activities such as fishing, rafting, and camping are popular along the river.

FAQ

About the Klamath River

Where does the data for the Klamath 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.
