Disease stemming from warm water in the North Umpqua River has killed 150,000 hatchery steelhead at a Roseburg area fish hatchery, marking the facility's second mass die-off this summer.
The Oregon Department of Fish and Wildlife alerted the public Friday to the deaths among its summer steelhead stock, blaming an historic drought that has heated the Umpqua's water and allowed pathogens to thrive.
