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

Natchaug River

The Natchaug River is a 17.5 mile-long tributary of the Shetucket River that runs through eastern Connecticut. Originally used by Native Americans for freshwater fishing, the river played an important role in the development of the textile industry in the 19th century. Today, the river is used primarily for recreation, including fishing, canoeing, and hiking. The river is fed by several small tributaries and is home to a variety of fish and wildlife, including trout and bald eagles. The river flows through several reservoirs, including the Mansfield Hollow Reservoir, which was constructed in the 1950s to provide drinking water to the nearby town of Mansfield. There are also several dams along the river, which provide hydroelectric power and regulate water flow. The Natchaug River is an important natural resource in the region, providing both recreational and agricultural opportunities.

FAQ

About the Natchaug River

Where does the data for the Natchaug 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.
