Dakota News Now reports the Army Corps of Engineers is beginning an environmental assessment of a project to repair the drainage system under Gavins Point Dam on the Missouri River near Yankton.

According to Gavins Point Project Manager Tom Curran, every dam has a system to control water seeping under it.  The Corp is planning to repair damage to this system with the goal of relieving pressure on the dam to prevent a potential blow out.

Curran hopes the project will start by late this year and is expected to last into next summer.

The flooding in March of 2019 raised Lewis & Clark Lake to record levels creating extra pressure on the drainage system.
