Total streamflow across the Huron River was last observed at 621 cfs, and is expected to yield approximately 1,232 acre-ft of water today; about 46% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 1,364 cfs, with recent peaks last observed on 2013-07-11 when daily discharge volume was observed at 17,563 cfs.

Maximum discharge along the river is currently at the Huron River At Ann Arbor reporting a streamflow rate of 342 cfs. This is also the highest stage along the Huron River, with a gauge stage of 12.43 ft at this location. This river is monitored from 4 different streamgauging stations along the Huron River, the highest being situated at an altitude of 883 ft, the Huron River At Milford.

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

Huron River

The Huron River is a 130-mile-long river in southeastern Michigan. It was named after the Huron tribe who once inhabited the area. The river flows through several cities, including Ann Arbor, Ypsilanti, and Flat Rock. The Huron River's hydrology is primarily influenced by rainfall and snowmelt, with its flow regulated by three dams: Barton, Argo, and Geddes. The river serves as a source of drinking water for several communities and provides recreational opportunities for fishing, boating, and swimming. The Huron River also supports agriculture, with several farms located along its banks, producing crops such as soybeans, corn, and wheat. The river has a rich history, with Native Americans using it as a transportation and trading route and later serving as a source of power for mills and factories.

FAQ

About the Huron River

Where does the data for the Huron 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.
