Blog: Drought ‘refuges’ protect young coho salmon from summer heat
The researchers discovered that salmon survival depends in part on how long isolated pools spend disconnected from flowing water: the longer the dry period, the fewer salmon were able to hang on until the wetter months of fall and winter. And though fewer salmon overall survived the drought years, the researchers did find reason for hope. In certain streams and pools, which the researchers call drought “refuges,” salmon survival was similar in both drought and non-drought years.
