Total streamflow across the Kankakee River was last observed at 10,116 cfs, and is expected to yield approximately 20,065 acre-ft of water today; about 67% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 15,065 cfs, with recent peaks last observed on 2018-02-22 when daily discharge volume was observed at 79,130 cfs.

Maximum discharge along the river is currently at the Kankakee River Near Wilmington reporting a streamflow rate of 3,470 cfs. However, the streamgauge with the highest stage along the river is the Kankakee River At Davis with a gauge stage of 6.24 ft. This river is monitored from 6 different streamgauging stations along the Kankakee River, the highest being situated at an altitude of 682 ft, the Kankakee River At Davis.

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

Kankakee River

The Kankakee River is a 133-mile river that flows through Indiana and Illinois. It was historically used for transportation and provided a source of water for agriculture. The river has a diverse ecosystem, with over 200 species of fish, including several endangered species. The river's hydrology has been altered by the construction of several reservoirs and dams, including the Kankakee River State Park Dam and the Wilmington Dam. These dams have been built for flood control, hydroelectric power, and recreation. The river is a popular destination for boating, fishing, and camping. The river and its surrounding wetlands also provide important habitat for waterfowl and other wildlife. Agriculturally, the river is used as a source of irrigation for corn, soybeans, and other crops.

FAQ

About the Kankakee River

Where does the data for the Kankakee 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.
