Total streamflow across the Little Menomonee River was last observed at 17 cfs, and is expected to yield approximately 34 acre-ft of water today; about 132% of normal. River levels are high. Average streamflow for this time of year is 13 cfs, with recent peaks last observed on 2026-04-16 when daily discharge volume was observed at 1,214 cfs.

Maximum discharge along the river is currently at the Little Menomonee River At Milwaukee reporting a streamflow rate of 14.5 cfs. This is also the highest stage along the Little Menomonee River, with a gauge stage of 3.67 ft at this location. This river is monitored from 2 different streamgauging stations along the Little Menomonee River, the highest being situated at an altitude of 729 ft, the Little Menomonee River Near Freistadt.

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

Little Menomonee River

The Little Menomonee River is a 14-mile river located in southeastern Wisconsin that runs between Menomonee Falls and Milwaukee. Historically, the river was used for milling and other industrial activities. Today, it is primarily used for recreation and agriculture. The river is fed by numerous tributaries, including the Little Menomonee Creek and the Mequon Creek. It is also home to several reservoirs and dams, including the Little Menomonee River Dam and the Silver Spring Dam. These dams help to control the flow of the river and provide water for agricultural and recreational purposes. The Little Menomonee River is a popular destination for fishing, kayaking, and canoeing, and it is home to a variety of aquatic wildlife, including bass, trout, and pike.

FAQ

About the Little Menomonee River

Where does the data for the Little Menomonee 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.
