Total streamflow across the Musconetcong River was last observed at 159 cfs, and is expected to yield approximately 315 acre-ft of water today; about 47% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 339 cfs, with recent peaks last observed on 2021-09-02 when daily discharge volume was observed at 4,860 cfs.

Maximum discharge along the river is currently at the Musconetcong River Near Bloomsbury Nj reporting a streamflow rate of 134 cfs. However, the streamgauge with the highest stage along the river is the Musconetcong River At Outlet Of Lake Hopatcong Nj with a gauge stage of 1.58 ft. This river is monitored from 2 different streamgauging stations along the Musconetcong River, the highest being situated at an altitude of 923 ft, the Musconetcong River At Outlet Of Lake Hopatcong Nj.

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

Musconetcong River

The Musconetcong River is a tributary of the Delaware River that runs for approximately 45 miles through northwestern New Jersey. The river has a rich history, having been used for transportation and industry since the 1700s. It is home to several reservoirs and dams, including the Lake Hopatcong and the Merrill Creek Reservoir, which provide drinking water to nearby communities. The river is also a popular recreational spot, with activities such as fishing, kayaking, and hiking. In recent years, efforts have been made to protect the Musconetcong River and its surrounding habitats through conservation and restoration programs. Additionally, the river plays an important role in agriculture, as it provides irrigation for farms in the area.

FAQ

About the Musconetcong River

Where does the data for the Musconetcong 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.
