a) before removal - A local landowner whose property is on the Sandusky State and Scenic River expressed concern with the breaching of St. John's Dam. He also objected to the use of public funds to cover the cost of removal. DNR responded to his objections and continued to proceed with the project.
b) during removal - As part of the pre-dam removal data set at the St. John's Dam, a team of OSU researchers was preparing to deploy equipment and make some morphological/hydraulic measurements in the channel on the morning of November 14, 2003. The dam was breached early and as a result the researchers were unable to deploy five bed load traps. In addition, they were also prevented from conducting transects across the downstream channel to measure current velocities and bed topography. Unfortunately, water levels remained high that weekend. Consequently, they were unable to deploy the remaining traps before the complete removal of the dam on Monday, November 17, 2003. The data from these traps and surveys would have been important for quantifying bed load transport associated with the removal.
When the dam was removed problems were encountered with sloughing of the banks near some homes. This problem was partially attributed to the fact that the dam was removed in a couple of hours, thereby creating high water levels downstream over the next couple of days. As a result, the banks became saturated with water and sloughing problems occurred. It is conceivable that had the dam been lowered and eventually removed over a couple of days it might have lessened this problem.
c) after removal - The Ohio Department of Transportation (ODOT) sent a Geotechnical Engineer to evaluate the sloughing problem that occurred at Locust Grove. After careful review, it was determined that the worst of the problems were over. The situation was compounded by the fact that the Locust Grove development was built primarily on fill material.
