Total streamflow across the Tangipahoa River was last observed at 2,105 cfs, and is expected to yield approximately 4,175 acre-ft of water today; about 154% of normal. River levels are high. Average streamflow for this time of year is 1,369 cfs, with recent peaks last observed on 2016-08-14 when daily discharge volume was observed at 82,730 cfs.

Maximum discharge along the river is currently at the Tangipahoa River At Robert reporting a streamflow rate of 1,690 cfs. This is also the highest stage along the Tangipahoa River, with a gauge stage of 10.8 ft at this location. This river is monitored from 2 different streamgauging stations along the Tangipahoa River, the highest being situated at an altitude of 232 ft, the Tangipahoa River At Osyka.

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

Tangipahoa River

The Tangipahoa River is located in southeast Louisiana and flows for 125 miles before emptying into Lake Pontchartrain. Named after the Tangipahoa Native American tribe, it has played an important role in the region's history, serving as a transportation route for goods and people.

The river is fed by numerous tributaries and has several reservoirs and dams, including the Percy Quin State Park Lake and the Tangipahoa Reservoir. These reservoirs are used for flood control, recreation, and as a source of drinking water for nearby communities.

The Tangipahoa River is an important source of irrigation for agricultural land along its banks, supporting rice farming, soybeans, and cattle grazing. The river is also a popular destination for recreational activities such as fishing, kayaking, and swimming.

Despite its importance to the region, the Tangipahoa River has faced environmental challenges in recent years, including pollution and sedimentation. However, efforts are underway to restore the health of the river and preserve its ecological and economic value for future generations.

FAQ

About the Tangipahoa River

Where does the data for the Tangipahoa 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.
