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

Suncook River

The Suncook River is a tributary of the Merrimack River located in central New Hampshire, USA. The river stretches 35 miles from its source in the Merrimack Valley to its confluence with the Merrimack River in Pembroke. The Suncook River has a rich history, from being a source of power in the early 1800s to being a popular destination for recreational activities today. The river is home to several reservoirs and dams, including Turkey Pond Dam, Northwood Lake Dam, and Suncook Dam. These dams provide hydroelectric power and control the water flow of the river. In addition, the Suncook River is an important source of water for agriculture and drinking water for local communities. Recreational activities on the river include fishing, canoeing, kayaking, and swimming.

FAQ

About the Suncook River

Where does the data for the Suncook 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.
