Jefferson County authorities, aided by several agencies, are coordinating a major search today for a man who apparently fell into the Lower Deschutes River near the Trout Creek campground Sunday night. Witnesses told deputies they saw the man in the water, heading downriver past the boat launch at the campground, located where Trout Creek flows into the Deschutes near the Jefferson-Wasco County line. The accident happened Sunday night around 9 p.m. and search efforts were hampered by darkness. The name of the man has not been released yet. In today’s search, Jefferson County Sheriffs Captain Heckathorn says they will be scouring the riverbanks while others work on the water in kayaks, inflatable boats, drift boats and motorized boats as well.  The Lower Deschutes is usually closed to motorboats, but they will be allowed for today's search.
