East Reservoir: Sand berms completed, deep-soil mixing continues

Posted on 5/15/2018 by Engineering in Portage Lakes

Sand berm construction along the main embankment near the 252 Portage Lakes Drive property recently was completed. The south embankment berm near the Clock Tower was completed in January. These sand berms provide the staging area and work platform for building the new dam. Deep-soil mixing has been underway along the south embankment and expected to be finished by the end of May. Starting mid-May, a bypass at the north embankment near the Cat Swamp will begin construction to allow for sand placement off of Portage Lakes Drive while minimizing impacts to local traffic. Flaggers will assist with traffic flow. ODNR understands the importance of recreational opportunities to the community and is planning to raise the water level incrementally during May in preparation for the 2018 summer boating season.  This approach best balances the needs of the community and our commitment to public safety. In early spring, ODNR lowered the water level at East Reservoir due to heavy rains.  While our commitment to minimize the impact of this project on the community remains, public safety must come first.  Understanding that a dam under construction is more vulnerable, ODNR will continue to proactively manage the water levels at Portage Lakes. This process will be weather dependent and involve close observation and monitoring; the goal is to soon return lake levels to normal summer pool.
