Williamson River river
Total streamflow across the Williamson River was last observed at 1,241 cfs, and is expected to yield approximately 2,461 acre-ft of water today; about 104% of normal. Average streamflow for this time of year is 1,194 cfs, with recent peaks last observed on 2017-03-25 when daily discharge volume was observed at 5,666 cfs.
Maximum discharge along the river is currently at the Williamson River Blw Sprague River Nr Chiloquin reporting a streamflow rate of 563 cfs. This is also the highest stage along the Williamson River, with a gauge stage of 3.5 ft at this location. This river is monitored from 2 different streamgauging stations along the Williamson River, the highest being situated at an altitude of 4,494 ft, the Williamson River Near Klamath Agency.

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.

Williamson River
The Williamson River is a tributary of the Klamath River located in Oregon, USA. It is approximately 100 miles long and has a drainage area of 1,370 square miles. The river is named after Robert Williamson, a member of John C. Fremont's 1843 expedition. The river's hydrology is characterized by cold, clear water and abundant fish populations, including native redband trout. The Upper and Lower Klamath Lake Reservoirs on the river were created by dams for irrigation and flood control purposes. The Upper Klamath Lake Reservoir is also home to the largest freshwater fishery in Oregon. Recreational activities on the Williamson River include fishing, kayaking, and camping. The river also plays a significant role in the agricultural industry, providing water for crops and livestock.

Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the Williamson River
Where does the data for the Williamson 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.
