Marys River river
Total streamflow across the Marys River was last observed at 139 cfs, and is expected to yield approximately 275 acre-ft of water today; about 38% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 363 cfs, with recent peaks last observed on 2012-01-19 when daily discharge volume was observed at 8,922 cfs.
Maximum discharge along the river is currently at the Marys River Near Philomath reporting a streamflow rate of 98.4 cfs. This is also the highest stage along the Marys River, with a gauge stage of 3.3 ft at this location. This river is monitored from 3 different streamgauging stations along the Marys River, the highest being situated at an altitude of 5,950 ft, the Marys River Below Orange Bridge Nr Charleston Nv.

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.

Marys River
The Marys River is a river in western Oregon that flows for approximately 41 miles from the Coast Range to the Willamette River. It was named after a Native American tribe that lived in the area. The river has historically been used for fishing by the local tribes and later for logging and transportation. It also has been a source of water for agriculture and drinking water for nearby towns. The river is dammed at two locations, the first being the Marys River Dam, which creates the Starker Reservoir, and the second being the Woods Creek Dam, which creates the Woods Creek Reservoir. These reservoirs are used for water storage, flood control, and hydroelectric power generation. The Marys River is a popular spot for recreation, including fishing, kayaking, and hiking along its banks.

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