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

Chewuch River

The Chewuch River is located in the northern region of Washington state and is approximately 53 miles long. Historically, the river was home to indigenous tribes and was used for transportation and fishing. Today, the river is an important source of irrigation for local agriculture and provides recreational opportunities such as fishing, kayaking, and camping. The river is fed by snowmelt and has a hydrology that is heavily influenced by seasonal changes. The river is also home to a number of reservoirs and dams, including the Molson and Buzzard Creek dams, which help manage water flow throughout the year. Despite ongoing challenges related to water management and climate change, the Chewuch River continues to be an important resource for both local communities and the natural environment.

FAQ

About the Chewuch River

Where does the data for the Chewuch 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.
