Total streamflow across the Muddy River was last observed at 43 cfs, and is expected to yield approximately 86 acre-ft of water today; about 101% of normal. Average streamflow for this time of year is 43 cfs, with recent peaks last observed on 2023-03-16 when daily discharge volume was observed at 1,535 cfs.

Maximum discharge along the river is currently at the Muddy R Nr Moapa reporting a streamflow rate of 44.4 cfs. However, the streamgauge with the highest stage along the river is the Muddy R Nr Glendale with a gauge stage of 13.3 ft. This river is monitored from 3 different streamgauging stations along the Muddy River, the highest being situated at an altitude of 1,719 ft, the Muddy R Nr Moapa.

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

Muddy River

The Muddy River is a 17.6-mile-long river in Massachusetts that flows through several towns and eventually empties into the Connecticut River. The river has a long history of being used for various purposes, including mills, factories, and farms. The hydrology of the river has been significantly altered by the construction of several dams and reservoirs, including the Upper and Lower Mystic Lakes, which provide drinking water to the Boston area. In addition, the river is used for recreational activities such as fishing, canoeing, and hiking, and is home to several species of fish and wildlife. Agriculture is also a significant use of the Muddy River, with several farms located along its banks. Despite its historical significance, the Muddy River has faced environmental challenges, including pollution and water quality issues, which continue to be addressed by local and state authorities.

FAQ

About the Muddy River

Where does the data for the Muddy 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.
