Total streamflow across the Greenbrier River was last observed at 10,129 cfs, and is expected to yield approximately 20,091 acre-ft of water today; about 177% of normal. River levels are high. Average streamflow for this time of year is 5,718 cfs, with recent peaks last observed on 2021-03-02 when daily discharge volume was observed at 110,980 cfs.

Maximum discharge along the river is currently at the Greenbrier River At Hilldale reporting a streamflow rate of 4,340 cfs. This is also the highest stage along the Greenbrier River, with a gauge stage of 4.87 ft at this location. This river is monitored from 4 different streamgauging stations along the Greenbrier River, the highest being situated at an altitude of 2,729 ft, the Greenbrier River At Durbin.

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

Greenbrier River

The Greenbrier River is a 173-mile-long river located in West Virginia, USA. It flows from the Appalachian Mountains to the New River and has played an important role in the state's history, serving as a transportation route for Native Americans and European settlers. The river is fed by numerous tributaries and has a varied hydrology, with rapids, pools, and riffles. The river's flow is managed by several reservoirs and dams, including the Burnsville Dam and the Bluestone Dam. These dams have helped to control flooding and provide hydroelectric power. The Greenbrier River is also a popular destination for recreational activities such as fishing, kayaking, and tubing. It is surrounded by forests and farms, which contribute to the region's agricultural economy.

FAQ

About the Greenbrier River

Where does the data for the Greenbrier 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.
