The cornerstone of project efficiency is controlling the water with the least impact to the river and its aquatic residents. Here you see another coffer dam being constructed, this time from large bulk sand bags. This temporary dam will keep the river from interacting with our project area when the flow of water over the dam is restored. You can see in the background that the bedrock removal has already begun.
