Total streamflow across the Milwaukee River was last observed at 355 cfs, and is expected to yield approximately 704 acre-ft of water today; about 15% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 2,370 cfs, with recent peaks last observed on 2018-05-14 when daily discharge volume was observed at 24,870 cfs.

Maximum discharge along the river is currently at the Milwaukee River Near Cedarburg reporting a streamflow rate of 355 cfs. However, the streamgauge with the highest stage along the river is the Milwaukee R @ Jones Island Mouth-At Milwaukee with a gauge stage of 9 ft. This river is monitored from 3 different streamgauging stations along the Milwaukee River, the highest being situated at an altitude of 672 ft, the Milwaukee River Near Cedarburg.

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

Milwaukee River

The Milwaukee River is a 115-mile-long tributary of Lake Michigan that flows through Wisconsin. In the late 19th and early 20th centuries, the river was heavily polluted due to industrialization, but has since been cleaned up and is now popular for recreational activities such as kayaking and fishing. The river's hydrology is managed by several man-made reservoirs and dams, including the Menomonee and Kinnickinnic Rivers, which were dammed to create power for industrial use. These reservoirs also help control flooding in the area. The river is used for agricultural irrigation and is important for the region's economy. Today, the Milwaukee River is a symbol of the city's ongoing revitalization and commitment to environmental sustainability.

FAQ

About the Milwaukee River

Where does the data for the Milwaukee 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.
