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.
