Clearly you only want to dump the ashes not the container so no need to remove identification. I am spreading my husband, my mother and my fathers ashes on the lake as per their requests. I am not doing the entire containers, some is spread over the ocean and some is buried in plots depending on each persons requests. I would just say go to whatever area of the lake you love take a small plastic container of the ashes you wish to spread, say a prayer and let the wind take the ashes over the lake....no one is the wiser and your loved one will forever be "one with the lake"
