Area where tank once stood is now a city parking lot and river walk area. The water tank Saidgeoteam is referring to is probably an old fire control water tank located on a building between 2nd and 3rd street located one block up. I was doing research at the Linn County Historical Museum, which by the way was in fact located at the same spot near where the tank was, their building was also turned into the parking lot.
