It’s the time of year when spring chinook come into the Deschutes River to spawn. As of yesterday morning, 28 of them have moved through Opal Springs Dam into the Crooked River. Right now there are survivable flows in the Crooked below the North Unit Irrigation District diversion just above Smith Rocks. When the flows out of Bowman Dam are reduced to 10 cfs in August, however, any remaining adults, their eggs, and any fry that have hatched will be in mortal peril.
