Le Sueur County was awarded an Accelerated Implementation Grant funded by the Clean Water Land and Legacy Amendment to conduct subsurface sewage treatment system (SSTS) compliance inspections and provide septic information and education within an area around Frances, Rays, Sakatah, and Tetonka Lakes.

On October 18, 2016, the Le Sueur County Board of Commissioners voted 5 ayes and 0 nays to adopt an Ordinance requiring mandatory SSTS compliance inspections and continuous SSTS compliance on properties within 350 feet of the ordinary high water level of Frances, Rays, Sakatah, and Tetonka Lakes.
