MY son and I were approaching the bank (north) of the Nooksak River when the bottom of the canoe struck an object beneath the surface of the water.  The craft overturned.  I mamanged to grap a branch while holding on to the canoe.  After bailing out much water, we attempted to board the craft.  The craft floated long enough for me to remember I weighed 120 # more than my son.  With the remaining water now rushing to my end of the craft it quickly filled w/ water and sank/ drifted away from us.
