Fire heavily damaged a building on Oak Street in downtown Hood River on Wednesday night.  Hood River Fire Chief Leonard Damian says firefighters were called to the fire at the building on 6 Oak Street that houses the Kayak Shed at 7:44 p.m. when multiple callers to 9-1-1 reported smoke and flames coming from the roof and the rear of the building.  Crews arrived to find dark smoke coming from the eaves of the building and fire coming from the roof.  Firefighters battled the fire for over 90 minutes before it was declared under control.  The fire was contained within the building, with an adjacent coffee shop and apartment building suffering what Damian termed moderate smoke and water damage.  There were no reported injuries, and all occupants in apartment units got out safely.  Damian says the cause of the fire has not yet been determined.   Crews from Hood River, Westside, Wy’east, Parkdale, Cascade Locks, Klickitat County, and Mid-Columbia Fire and Rescue departments were involved in the firefighting effort.  The fire attracted a large number of onlookers who were in the downtown area on a warm early fall evening.
