Emptying a fresh water tank is NOT illegal anywhere. The water in the truck they use to wet down the road is not fresh water. As a matter of fact it is not even considered potable water because potable water can be consumed without getting people sick. So if you can't dump fresh water then how come the Rangers don't give the driver of the water truck a ticket. There are no rules anywhere that say you can't spill fresh water. There are rules against dumping holding tanks of gray or black water which is considered biohazardous material. Fresh water is just that and will always be just that. I repeat again, Fresh water can be spilled without penalty. Show me some rules to prove me wrong.
