(Detroit, OR)  --  The U.S. Army Corps of Engineers has released plans to proceed with the larger than usual drawdown on Detroit Lake this fall.  A federal judge ruled this week that the Corps can proceed with the plan, which is required to improve salmon runs.  Marion County and the City of Salem plan to appeal the decision.  The Army Corps will host a virtual public meeting November 18th to explain the plan, when it will start and how long it will last.  It includes how it's coordinating with state agencies and drinking water facilities to address concerns if they arise.
