MANDAREE, N.D. -

A Montana man is presumed drowned in Lake Sakakawea (suh-kaw-kuh-WEE'-uh) in North Dakota after he fell out of a boat and officials unsuccessfully searched for him over the weekend.
    
State game warden Brian Updike says the man was fishing in the Skunk Bay area in Dunn County on Saturday morning when he fell into the water and did not resurface. Authorities have not released the name of the 49-year-old man from Sidney, Mont.
    
Officials say the area where the man went into the water is known for large boulders on the lake bottom. Access to the area also has been hampered by muddy conditions.
