Grand Tower and Degognia Levee System

The Grand Tower and Degognia and Fountain Bluff levee system is locally operated and maintained by Grand Tower Drainage & Levee District and Degognia and Fountain Bluff Levee & Drainage District. The levee system was completed in the 1950s, and is federally authorized to reduce the risk of flooding from the Mississippi and Big Muddy Rivers to the communities of Cora, Jones Ridge, Raddle, Jacob, Gorham, and Grand Tower in Illinois. During 2019, it is estimated the system prevented more than $105 million in flood damages.

Levee systems are part of our nation’s landscape and important to communities because of the benefits they provide. For example, more than ten million people live or work behind levees in the U.S. Army Corps of Engineers’ Levee Safety Program. And, public and private property worth more than one trillion dollars are behind these levees.

The U.S. Army Corps of Engineers’ Levee Safety Program works with local levee sponsors and stakeholders to make sure these levees provide their intended benefits. Working together to assess, manage and communicate flood risks to residents and businesses is our priority because, more than anything, life safety is paramount.

Our partners play an important role in levee safety because we all must work together, sharing responsibility, to solve and manage flood risk management challenges. Ultimately, individuals who know what to do before a flood or storm happens can make our communities safer places to live and work.
