Rescue crews are still looking for a missing fisherman on Lake Ray Hubbard.

Jason Evans with Dallas Fire-Rescue says a 50-year-old man disappeared while fishing at about 7 p.m. Wednesday. His boat was found capsized.

Crews have been in the water since early Saturday morning. Officials said as many as six boats searched throughout the day. Dallas Fire-Rescue continues to assist in the search.

The Texas Game Warden and DFR crews will continue to look for him after his boat was found capsized, Evans said. They'll use sonar equipment and will search the ground along the shore.

A 911 call was place with DFR Thursday morning by a relative who said the fisherman hadn't been seen since taking his boat out Wednesday night. The relative said the man usually fished in the same area, along the Highway 66 bridge, and usually didn't stay out too long, Evans said.

The fisherman's trailer and vehicle were found at the Highway 66 ramp.
