Total streamflow across the Sturgeon River was last observed at 1,454 cfs, and is expected to yield approximately 2,884 acre-ft of water today; about 100% of normal. Average streamflow for this time of year is 1,447 cfs, with recent peaks last observed on 2026-04-19 when daily discharge volume was observed at 10,120 cfs.

Maximum discharge along the river is currently at the Sturgeon River Near Alston reporting a streamflow rate of 556 cfs. However, the streamgauge with the highest stage along the river is the Sturgeon River Near Nahma Junction with a gauge stage of 5.16 ft. This river is monitored from 4 different streamgauging stations along the Sturgeon River, the highest being situated at an altitude of 1,228 ft, the Sturgeon River Near Sidnaw.

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

Sturgeon River

The Sturgeon River is a 106-mile-long river that flows through northern Michigan. It starts in the northeastern part of the state and flows southwest into the Cheboygan River. The river has played a significant role in the region's history, having been used by Native Americans and early settlers for transportation and trade. Today, the river's hydrology is impacted by two major reservoirs, the Burt Lake Reservoir and the Mullett Lake Reservoir, which were created by dams built in the late 1800s. These reservoirs are used for hydroelectric power generation and also provide recreational opportunities for boating and fishing. The Sturgeon River and its tributaries also support agricultural activities such as cattle grazing and hay production.

FAQ

About the Sturgeon River

Where does the data for the Sturgeon 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.
