A small fire at the Commodore Building in The Dalles early Friday morning set off the building sprinkler system, leading to water damage in a number of units in the facility. The Dalles Police Chief Jay Waterbury termed the fire “very small” and an investigation is underway. Mid-Columbia Fire and Rescue Division Chief Jay Wood said activation of the sprinkler system left five units in the building uninhabitable, displacing seven people and at least three animals. Damage occurred on the first floor, second floor, and in the basement. The American Red Cross is assisting those who have been displaced. The fire occurred around 4:45 a.m. Friday.
