1950 Summary
General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
The Mississippi and White River Below Helena levee system provides flood risk reduction for portions of eastern Arkansas. The levee system extends south form Helena, Arkansas to the mouth of the White River along the Mississippi then heads north along the east bank of the White River. The levee system consists of 6 levee segments totaling 114.4 miles of levee. The levee systems prevents flooding from the Mississippi River and White River.
The levee system is part of the Mississippi River and Tributaries (MR&T) project. The MR&T project was authorized by the 1928 Flood Control Act. In the wake of the devastating 1927 flood, it was deemed necessary to put into place a comprehensive, unified system of public works within the lower Mississippi Valley that would provide unprecedented flood risk management and an equally efficient navigation channel. The MR&T project continues to be one of the world’s most comprehensive and successful flood risk reduction projects.
