A barge carrying a two-story home became stuck near where the Mokelumne River and San Joaquin Rivers intersect in the Sacramento River Delta.   The small vessel towing the barge had lost control of the steering allowing the barge to run aground.    The barge and house listing to one side some 200 feet from shore.   The Coast Guard has issued an alert since there are no lights on the structure to alert boaters of its location at night.     The barge was being towed from Sacramento to Helen, California.    Some damage to the home is expected as it rests partially submerged.
