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

Skykomish River

The Skykomish River is a 29-mile long river in northwestern Washington, USA. It originates from the Cascade Mountains and flows into the Snohomish River. Historically, the river was used for transportation and logging. Today, it is popular for recreational activities such as fishing, kayaking, and rafting. The Skykomish River is also used for agricultural purposes such as irrigation. The river's hydrology is primarily fed by snowmelt and rainfall. There are several reservoirs and dams along the river, including the Culmback Dam and the Sunset Falls Dam, which provide hydroelectric power to the surrounding areas. The Skykomish River is an important natural resource for the region, and efforts are being made to preserve its ecological and recreational values.

FAQ

About the Skykomish River

Where does the data for the Skykomish 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.
