This is the latest update provided by the Project Manger at 3:15pm on Sunday: The construction area at the dam site is stabilized and the flow of water below the dam has returned to a normal level. Work crews monitored the construction area and road crossings overnight to keep the area secure.
It is believed that the river crested at Beitner Road Bridge at approximately 11:30 p.m. last night, at 4.5 â?? 5 feet above normal levels. The public is urged to use caution when approaching or entering the river due to debris that continues to float downstream.
Vehicle and foot traffic congestion in the area continues to be a concern. The public is urged to use designated parking and viewing areas at the overlooks located on Ranch Rudolph Road, and at the canoe launch on Brown Bridge Road.
The project team at this time is focused on the following: Bridge inspection and reopening of roads, Downstream reconnaissance, Continued sediment monitoring, Assistance for those affected by the incident.
Qualified bridge inspectors from MDOT as well as private consulting engineers are completing affected county road crossings. Crossings on River Road and Garfield Road have been completed and those roads have been reopened. Following satisfactory inspection results, all county roads in the area will be reopened. Private road crossings will also be inspected.
