PIERRE, S.D.(KCCR)- Pierre City Commissioners were updated this week on the activities of M-SAC or the Missouri Sedimentation Action Coalition.  Missouri River cities like Pierre are members and Paul Lepisto is serving a three-year term on the board, appointed by Pierre.  Lepisto says M-SAC is in Phase Two of four to find solutions to mitigate sediment deposits in the Missouri River.

The focus for M-SAC on the Missouri River is Lewis and Clark Lake on the south end of the reservoir system.

While the sedimentation plan is focused on Lewis and Clark Lake sediment along the river could be a future issue.

Lewis and Clark Lake could half full of sediment by 2045 if the sedimentation isn’t mitigated.
