Roscommon commissioners cite safety concerns, data mismatch at Houghton Lake structure

The Roscommon County Board of Commissioners on May 13 discussed safety and measurement concerns at the Houghton Lake control structure after a Michigan Department of Natural Resources survey crew reported differing measurements from county logs. Chair Darlene Sensor said the county has been keeping data logs on all three structures since the beginning of May and described the DNR as using an "88 datum" while the county uses a "29 datum." The DNR, Sensor said, acknowledged it is not maintaining the structure at the county's level and indicated it has no intention of inserting stop logs at this time.
