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

Santiam River

The Santiam River is a 110-mile river located in the Willamette Valley of western Oregon. The river is sourced from the Cascade Range and flows into the Willamette River near Salem. Historically, the Santiam River was used by Native American tribes for fishing and trading. In the early 1900s, the river was dammed to create hydroelectric power, resulting in the formation of three reservoirs: Detroit Lake, Big Cliff Lake, and Green Peter Lake. These reservoirs now provide irrigation for agriculture and drinking water for communities in the region. The Santiam River is also popular for recreational activities such as fishing, boating, and hiking. The river is home to various species of fish, including Chinook salmon, steelhead trout, and rainbow trout.

FAQ

About the Santiam River

Where does the data for the Santiam 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.
