Pearl River river
Total streamflow across the Pearl River was last observed at 30,309 cfs, and is expected to yield approximately 60,117 acre-ft of water today; about 110% of normal. Average streamflow for this time of year is 27,587 cfs, with recent peaks last observed on 2020-02-22 when daily discharge volume was observed at 382,590 cfs.
Maximum discharge along the river is currently at the Pearl River Near Bogalusa reporting a streamflow rate of 11,100 cfs. This is also the highest stage along the Pearl River, with a gauge stage of 14.97 ft at this location. This river is monitored from 9 different streamgauging stations along the Pearl River, the highest being situated at an altitude of 382 ft, the Pearl River At Burnside.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

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.

Pearl River
The Pearl River is a major river system in the southeastern United States. The river flows for 485 miles through Mississippi and Louisiana, emptying into the Gulf of Mexico. The river has a rich history, playing a significant role in the Civil War and serving as a transportation route for Native American tribes.
The hydrology of the Pearl River is heavily influenced by several large reservoirs and dams, including the Ross Barnett Reservoir and the Bonnet Carré Spillway. These structures help manage flood control, water supply, and hydroelectric power generation.
Recreational activities along the Pearl River include fishing, boating, and camping. The river also supports agricultural activities, with farms and ranches along its banks producing crops such as cotton, soybeans, and rice. Despite its importance, the Pearl River faces threats from pollution and habitat destruction, highlighting the need for continued conservation efforts.

About the Pearl River
Where does the data for the Pearl 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.
