TOTAL RIVER DISCHARGE
Total streamflow across the
Calcasieu River
was last observed at
3,078
cfs, and is expected to yield approximately
6,105
acre-ft of water today; about 95%
of normal.
Average streamflow for this time of year is
3,242 cfs,
with recent peaks last observed
on
2020-10-12 when daily discharge volume was observed at
91,500 cfs.
Maximum discharge along the river is currently at the
Calcasieu River Near Kinder
reporting a streamflow rate of 1,860 cfs.
However, the streamgauge with the highest stage along the river is the
Calcasieu River Nr Glenmora
with a gauge stage of 8.85 ft.
This river is monitored from 3 different streamgauging stations along the Calcasieu River, the highest being situated at an altitude of 121 ft, the
Calcasieu River Nr Glenmora.
The Calcasieu River is a 200-mile-long river located in Southwest Louisiana. It was originally used by Native American tribes for transportation and fishing. French explorers named the river after the Atakapa word "quelqueshue," meaning "crying eagle." The river is home to several reservoirs and dams, including the Toledo Bend Reservoir and the Sam Rayburn Reservoir. These reservoirs provide hydroelectric power, as well as recreational opportunities for fishing, boating, and camping. The Calcasieu River also plays a vital role in Louisiana's agriculture industry, providing irrigation for crops such as rice, soybeans, and sugarcane. The river's hydrology has been greatly impacted by human activity, including industrialization and levee construction, which has caused erosion and sedimentation. Conservation efforts are underway to protect and restore the river's ecological health.

History of the River
The Calcasieu River ( KAL-kə-shoo) is a river on the Gulf Coast in southwestern Louisiana. Approximately 200 miles (320 km) long, it drains a largely rural area of forests and bayou country, meandering southward to the Gulf of Mexico. The name "Calcasieu" comes (via French) from the Indian Atakapa language katkosh, for "eagle", and yok, "to cry".
The Calcasieu rises in Vernon Parish, north of Leesville, and flows initially southeast, passing through the Kisatchie National Forest southwest of Alexandria. It then turns southwest, flowing past Oakdale and Lake Charles, the largest city on the river. It enters the north end of the brackish Calcasieu Lake, an estuary on the Gulf of Mexico approximately 10 miles (16 km) southwest of Lake Charles. The lake, which is referred to by locals as "Big Lake", is connected by a 5-mile (8 km) channel to the gulf on the south end. The lower portion of the river south of Lake Charles is paralleled by a navigable canal which connects to the Gulf Intracoastal Waterway.
In the early 19th century, the area of present-day Louisiana and Texas west of the Calcasieu River extending roughly north-south to the Arroyo Hondo in Natchitoches Parish and east of the Neches River was disputed between the United States and Mexico. The dispute arose from differing interpretations of the western boundary of Louisiana under the terms of the Louisiana Purchase. The area became known as Neutral Ground and became a haven for privateers outside the legal jurisdiction of both nations. Because the river passes through areas intensive in petroleum refining and other industries, petrochemical wastes have been found contaminating the river and estuarine environment along the lower Calcasieu River. A 1993 Condea Vista Chemical Company pipeline spill was reported by the company to have leaked 1.6 million pounds of a highly toxic chemical known as ethylene dichloride. Mother Jones reported the spill as potentially discharging between 19 and 47 million pounds that would have spread throughout parts of the estuary. Sasol Ltd purchased Condea Vista in 2000 inheriting the controversy. The site was designated a "super-fund site" and Sasol has been involved in long term legal battles that have resulted in settlements, fines, and clean up of affected areas. A problem is that the chemical sinks in water and gets covered by deposits of silt. Cleanup would inherently disturb the covered chemical stirring it up causing further ecological damage. The lower end of the estimated spill (19 million tons) would be two times the 1988 US production of ethylene dichloride that was 9,445,000 tons. 1.6 million tons were cleaned up. Any construction might disturb contaminated soil so would have to be constantly monitored.
