Sublette County crews are assisting and providing equipment in the search for a missing man at Alcova Reservoir.

Natrona County Sheriff's Office Sgt. Sean Ellis said the crew from Sublette County arrived Monday. With them, Sublette county searchers brought a larger sonar unit and a submersible.

As of Tuesday morning, the man, who reportedly fell from a boat while fishing, has not been found.

Ellis said strong winds hindered search efforts Monday. The man's name has not been released.

The public is asked to avoid the Fremont Canyon area as workers carry out the search.
