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.

Hoko River
The Hoko River is located in the northwestern region of Washington State, USA. It is approximately 24 miles long and has a drainage basin of 69 square miles. The river was historically significant for the Lower Elwha Klallam tribe as it provided a source of salmon and other aquatic resources. Today, the Hoko River is primarily used for recreational activities such as fishing and kayaking, and also serves as a source of water for agriculture. The river is also home to several reservoirs and dams, including the Hoko Falls Dam, which was built in 1932 to generate hydroelectric power. The Hoko Falls Dam is currently decommissioned and slated for removal as part of a wider effort to restore the river's ecosystem.

Fishing access and paddle runs Snoflo tracks within the watershed.
Track the Hoko River in the Snoflo app
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 Hoko River
Where does the data for the Hoko 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.
