Did Ida Reverse The Flow Of The Mississippi River?<\/h2>\n

The Mississippi is a paramount river not just for the United States, but for the entire world. It is used for transportation, is a source of food, and is a part of the economy of many states along its route. As such, any changes to its condition have to be carefully planned and of utmost importance. One notable change, the 1928 Flood Control Act, seems to have reversed the natural flow of the river.<\/p>\n

In the early 20th century, the Mississippi River experienced heavy rainfall, leading to catastrophic flooding. As a result, the U.S Congress enacted the 1928 Flood Control Act. This gave the government full control over the river and its tributary dams, which allowed them to regulate the water level as necessary. However, the act also included a provision that effectively changed the river’s natural flow. In essence, the dams were placed upstream and the water was forced to go in the opposite direction than it would under normal circumstances.<\/p>\n

In addition to the Flood Control Act, a unique weather phenomenon known as Ida occurred around the same time. This weather vortex created by a strong air mass system reversed the normal air flow in the region, changing the weather patterns for an extended period of time and further affecting the river’s flow. Ida combined with the Flood Control Act to produce an artificial flow reversal in what had previously been a stable river system.<\/p>\n

This drastic change of the Mississippi’s flow did not go unnoticed. Experience river pilots, people who help guide ships along the river, have felt the effects of Ida and the 1928 Flood Control Act for generations. They noticed the “backwaters,” or currents located upstream that prevented ships from reaching the docks. This forced them to lower the riverbed levels and dredge the channels, making them much deeper and wider than they previously were.<\/p>\n
