The creek into Antoine is actually a creek into Ram Lake.  You would have to make a very short portage from Ram to Antoine.  The creek that flows from Ram to Sturgeon flows from the northeast side of Ram Lake.  I have taken the creek into Ram in 1972, 2004 and 2012.  Each time the creek seems to get smaller.  There isn't much elevation to the creek so if the water is low you could probably make your decision as you enter the creek.
