How was he found?

Moses was found on the Nile:

The birth of Moses occurred at a time when the current Egyptian monarch had commanded that all male children born to Hebrew captives should be killed by drowning in the Nile River. The Torah leaves the identity of this Pharaoh unstated, but he is widely believed to be Ramses II; other, earlier pharaohs have also been suggested including a Hyksos pharaoh or one shortly after the Hyksos had been expelled. Jochebed, the wife (and paternal aunt) of the Levite Amram, bore a son, and kept him concealed for three months. When she could keep him hidden no longer, rather than deliver him to be killed she set him adrift on the Nile river in a small craft of bulrushes coated in pitch. The daughter of Pharaoh discovered the baby and adopted him as her son, and named him "Moses" (Which means "to draw out"). By Biblical account, Moses' sister Miriam observed the progress of the tiny boat. Miriam then asked Pharoah's daughter if she would like a Hebrew woman to nurse the baby. Thereafter, Jochebed was employed as the child's nurse, and he grew and was brought to Pharaoh's daughter and became her son. http://en.wikipedia.org/wiki/Moses
