Bad news for Fish: lowest fall stream flows moving closer to summer's high temperature

"The problem is that these two events, high temperature and low flow, are very stressful for fish and other aquatic organisms," said Ivan Arismendi, the study's lead author and a research professor in OSU's Department of Fisheries and Wildlife. "Because these two extreme events are occurring more closely to each other, they have less time to recover or adapt to be ready for the next one."

The study, peer-reviewed and published in the journal Hydrobiologia, was funded and coordinated by the USGS and the research branch of the U.S. Forest Service. The authors also included Mohammad Safeeq and Roy Haggerty of OSU, Sherri Johnson of the Forest Service's Pacific Northwest Research Station, and Jason Dunham of the USGS Forest and Rangeland Ecosystem Science Center.
