 No repairs to the stonework have ever been needed.At the time of its construction it was the largest dam in the world, and it remains one of the significant landmarks defining the city to which its creation gave birth.It was so significant to the city at the time, a celebration was held in honor of its semi-centennial in 1895, yet now may be less celebrated, as at the site of the dam there is no viewing platform, monument or historical marker giving passersby information about the historical innovation and social marvel beneath their feet.
