Laws on cremains?

[HomeWood]

The "ashes" are just crushed up bone. The flesh, organs, etc are burned off. They are not like grill or fire ashes. They would just sink to the bottom and settle into the mud and muck on the bottom. What damage could possibly be done?

I've seen a family members ashes and one of my childhood dog's ashes. They looked exactly the same.

Personally, my wishes upon death are to be cremated and put to rest in the lake.
