A small grass fire Thursday morning on Hood River’s Heights was quelled quickly.  Westside Fire District Chief Jim Trammell says crews arrived to find four power lines going down from the Experiment Station/Tucker Road intersection to the Mid-Columbia Experiment Station.  The grass fire was about 100 feet by 200 feet in size, and two engine crews extinguished it quickly.  Trammell says crews were not sure why the lines were going down.  A blown transformer occurred as result, causing a power outage throughout the Heights that Pacific Power indicated for most customers lasted for about 20 minutes.  A handful of customers were without power as of late this morning.
