Unless you're hunting waterfowl where lead shot is prohibited or in an area where it is prohibited, such as a refuge, use of lead shot on public waterways is not against the law. Someone prove me wrong.

It appears I was wrong on this, and leads me to question the validity of the laws regarding the use on non-toxic shot for waterfowl.

Unless you are in a bird sanctuary, area prohibiting hunting or are shooting toward private property, an owner complaining about gun shots does not mean you have to quit hunting or that it is illegal, as turdspot stated here: [b]they sure as hell can if they are near private property and the owner complains [/b]

220-2-.139 Hunting or Discharging a Firearm Near a
Dwelling, etc.
It shall be unlawful for any person to hunt or attempt to hunt within 100
yards of any dwelling belonging to another, whether occupied or not, without
the permission of the owner or lessee of said dwelling. Provided further, it
shall be unlawful for any person to discharge a firearm while hunting in
such a manner that any projectile strikes any dwelling or building used
for human occupation, whether occupied or not, or any commercial vessel,
without the permission of the owner or lessee of said dwelling, building or
vessel. This regulation shall not apply to a landowner or member of his or
her immediate family hunting on his or her own property provided that no
projectile strikes any of the above stated property of another without the
permission of the owner or lessee of said property.

Show me the regulation prohibiting shooting a gun from a boat with the motor running. There isn't one unless you are pursuing specific game or waterfowl, and then it must be off and the vessel at a complete stop before you shoot. That's been in effect for waterfowling for years.

Wrong. Notice the "kill any bird or animal part".

220-2-.11 Prohibited Methods and Devices for Hunting
It shall be unlawful to concentrate, drive, rally, molest or to hunt, take,
capture or kill or attempt to hunt, take, capture or kill any bird or animal
from or by the aid of:
(1) Any automobile, motorcar, airplane, train, motorboat, sailboat or any
type mechanically propelled device, or any other device being operated
in conjunction with any of the above mentioned devices of
transportation. Provided, however, that nothing in this regulation shall
prevent hunting from a floating craft (except a sinkbox), including those
propelled by motor, sail and wind, or both, when the motor of such craft
has been completely shut off and/or the sails furled, as the case may be,
its progress therefrom has ceased, and it is drifting, beached, moored,
resting at anchor, or it is being propelled by paddle, oars or pole, and
provided further that nothing in this regulation shall prevent the taking
of game birds and game animals from any stationary motor vehicle or
stationary motor driven land conveyance provided any forward motion
is ceased and engine is shut off. Nothing in this regulation allows the
hunting, taking or killing or
attempting to hunt, take or kill any bird or animal from any vehicle on a
public road.

If you shoot a rifle from a moving boat at a snake then you're an idiot and deserve whatever happens. But I still want anyone to find me a law or regulation prohibiting that or any of the other things stated.

Perhaps you do deserve what could/would happen, and I will not dispute that. However, the guy standing across the river with his kid that gets hit with a ricocheting bullet does not.
