Umatilla River river
Total streamflow across the Umatilla River was last observed at 523 cfs, and is expected to yield approximately 1,037 acre-ft of water today; about 23% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 2,262 cfs, with recent peaks last observed on 2019-04-10 when daily discharge volume was observed at 23,710 cfs.
Maximum discharge along the river is currently at the Umatilla River Near Umatilla reporting a streamflow rate of 210 cfs. However, the streamgauge with the highest stage along the river is the Umatilla R At W Reservation Bndy Nr Pendleton with a gauge stage of 3.15 ft. This river is monitored from 3 different streamgauging stations along the Umatilla River, the highest being situated at an altitude of 1,871 ft, the Umatilla River Above Meacham Creek.

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.

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.

Umatilla River
The Umatilla River is a tributary of the Columbia River, located in northeastern Oregon. The river was historically home to the Umatilla Native American tribe, who fished and hunted along the river. The river runs for 89 miles, beginning in the Blue Mountains and flowing through the Umatilla National Forest. The river's hydrology has been impacted by the construction of several dams, including the McKay and Wildhorse Reservoirs. These dams provide irrigation water for agriculture and hydroelectric power. The river is also used for recreational activities such as fishing, boating, and camping. The Umatilla River supports populations of Chinook salmon, steelhead, and other fish species. Agricultural uses include the growing of wheat, hay, and fruit trees.

About the Umatilla River
Where does the data for the Umatilla 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.
