One weekend brush fire in Redding is under investigation by DEEP and Aquarion Police as it burned land along the Saugatuck Reservoir.  The other major brush fire in Redding happened Sunday afternoon in the Georgetown district.  Downed wires sparked that blaze.  About an acre burned along Portland Avenue.  While a tree limb was involved, fire officials say they're not sure to what exactly caused the wires to come down.  The fire burned between homes, but none were damaged.  Firefighters were able to stop the flames before they got any closer.  Crews were on scene for about two hours.
