Work session was opened by Leonard and he asked Bill Holman to give review of the request to identify dredging sites. Holman explained our permit from the Corp of Engineers requires a Cultural Resource Investigation which makes sure we won’t damage historic or archeologic areas. We did the archeology study on the lake bed and submitted our report to the Corp of Engineers and then the Corp referred the report to the State Historical and Preservation Organization (SHPO). The exercise tonight is to identify the areas where we might want to remove/dredge sand and sediment now and in the future. The Corp and SHPO want to make sure we won’t affect any areas where they have a concern. We need to show and prove to the Corp that when we dredge we will stay within the areas of where the lake was originally created and we won’t dig into terraces deeper than the original lake bed. We need to put a dredging plan together and then it will be included in the Memoradum of Agreement with the Corp.
Holman explained there are maps on the table that all will look at. Kray asked Holman to explain how the maps were created. Holman said when the lake was emptied the state did a fly over with radar and created Lidar data which shows what the terrain was like after the flood. Stanley then took this data and put it in their model that compared the Lidar data with what the normal pool level of the lake would be. These maps now show how deep the lake will be once the dam is rebuilt.
The attendees then reviewed all sections of the lake and gave their input. Peter made motion to adjourn and Leonard second, motion passed. The work session was adjourned at 7:40 pm.
