After three hours in the water, rescue teams were not able to locate or recover anyone.
Firefighters were called out to the canal off McKinley Avenue near Millbrook Avenue on Tuesday morning.
The Fresno Fire Department called the incident a "high hazard search." At one point, 30 crew members, including divers and surface swimmers, were scouring the water.
