REDMOND, OR -- An irrigation canal breach flooded roadways and prompted emergency alerts south of Redmond, Wednesday night, according to the Central Oregon Irrigation District. COID officials say the break in the Pilot Butte Canal occurred at about 9 p.m. on Young Avenue, between 61st and Canal Blvd. The canal was flowing at 250 cubic feet per second at the time. "We have stopped the flooding and are assessing how to help people who are impacted," COID Managing Director Craig Horrell said in a Thursday morning statement. "At this time, there is no projection of how long it will take to repair and restore the canal." Officials have confirmed the breach was caused by burrowing rock chucks, which led to the breaking up of canal banks. The extent of the damage is unclear. "We want to thank the Deschutes County Sheriff's Office and Deschutes County Road Department for their excellent emergency management support and equipment," said Horrell.
