Total streamflow across the Auglaize River was last observed at 728 cfs, and is expected to yield approximately 1,444 acre-ft of water today; about 14% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 5,274 cfs, with recent peaks last observed on 2015-06-18 when daily discharge volume was observed at 50,770 cfs.

Maximum discharge along the river is currently at the Auglaize River Near Defiance Oh reporting a streamflow rate of 595 cfs. This is also the highest stage along the Auglaize River, with a gauge stage of 6.43 ft at this location. This river is monitored from 3 different streamgauging stations along the Auglaize River, the highest being situated at an altitude of 805 ft, the Auglaize River Near Kossuth Oh.

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

Auglaize River

The Auglaize River is a tributary of the Maumee River, located in northwestern Ohio. It is approximately 113 miles long, starting in Fort Wayne, Indiana, and flowing eastward through Ohio. The river has a rich history, having been used by Native American tribes for fishing and transportation, and later by European settlers for logging and agriculture. The river's hydrology has been affected by human activity, with several reservoirs and dams built along its course for flood control and water supply. These include the Auglaize River Reservoir, the Defiance Reservoir, and the Ottawa Reservoir. The river supports recreational activities such as fishing, boating, and camping, and is also used for irrigation and agriculture.

FAQ

About the Auglaize River

Where does the data for the Auglaize 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.
