Step one of a $54 million project by Ameren Missouri to improve Bagnell Dam began this week. The concrete of the dam is currently being cleaned before holes will be drilled to place anchors. After the anchors are placed, over 66 million pounds of concrete will be poured to fasten the dam to the bedrock. The entire Bagnell Dam project is expected to take around 18 months. Ameren says they do not anticipate any extended road closures on the dam during the summer months.
