Officials alerted the public that the man and woman were never missing and that there was a miscommunication.
Investigators said the two are local residents. They told friends they were going to paddle north of Healdsburg Sunday. A worried friend called the sheriff this morning to say the two hadn't returned and weren't answering their cellphones.
Deputies did find their car, parked at the Alexander Valley campground five miles north of Healdsburg. Sheriff's officials say it's not clear what direction the two decided to go on the river.
