Total streamflow across the Cache River was last observed at 2,023 cfs, and is expected to yield approximately 4,013 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 3,024 cfs, with recent peaks last observed on 2018-03-03 when daily discharge volume was observed at 27,020 cfs.

Maximum discharge along the river is currently at the Cache River At Egypt reporting a streamflow rate of 1,450 cfs. This is also the highest stage along the Cache River, with a gauge stage of 13.27 ft at this location. This river is monitored from 3 different streamgauging stations along the Cache River, the highest being situated at an altitude of 367 ft, the Cache River At Forman.

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

Cache River

The Cache River is a 92-mile-long river in southern Illinois. It was once a major transportation route for Native Americans and played a crucial role in the development of the region. The Cache River is fed by numerous small streams and is home to a diverse array of aquatic life, including several endangered species. The river is managed by several government agencies, and several reservoirs and dams have been built along its length to regulate its flow and provide irrigation to nearby farms. Recreational opportunities along the Cache River include fishing, boating, hiking, and birdwatching. Agriculturally, the river is an important source of water for local farms, and numerous crops are grown in the region, including corn, soybeans, and wheat. Despite its importance, the Cache River is threatened by pollution, development, and climate change, and efforts are underway to protect and preserve this vital natural resource.

FAQ

About the Cache River

Where does the data for the Cache 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.
