The lastest that I heard is that any water that is reachable the ocean without having to breech a dam is considered Navigatable. The Coast Gaurd has a list of the river and mile marks of the rivers in our state that they consider navigatable. I am not trying to just point out Hook em up. I think there is so many guides on the water these days that do not have all of the requirements required by our state to guide, but are doing it anyhow without any regards to the saftey of there clients or the laws required by our state for them to guide. I am also not saying that the guides that are doing it are not qualified to run a guide service, but if your going to run a proffesional guide service then get the licenses you need to guide or don't guide. The guides that have all of there licenses spent there time and money. It's time and money spent for your clients safety and your guide service reputation and it is required.
