The State doesn't own any water. The people of the State own the water. That's not a small distinction.
The State has a trust obligation to ensure the waters of the State (owned by the people) are kept available for beneficial use. That means no wasted water, no impounded water that is withheld from public use and making sure any given beneficial use does not ruin the water for other members of the public.
The State does not own the beds of the navigable rivers, the people of the State do. Not just the water but the bed itself.
Before you attempt to make any decisions about the use of the public's waters or the use of a publicly owned navigable river bed you need to understand the distinction between the two. Water for mining is a beneficial use. The material on the bed of a river is not a beneficial use.
Water law is very complex and varies a lot from state to state. Until you get a grasp on the differences between water use, navigable river beds and submerged lands of the State you can easily be fooled by the different legal status of each.
Now that you know the distinction reread what jog wrote in his
previous post. He describes three types of property - public water, public navigable river beds and State owned submerged coastal lands.
There are at least three other classes of property not mentioned - free water that falls on your land in the form of rain, riparian water rights and the beds of rivers or streams that are not navigable. Those are private property rights, not public or State owned.
Notice that there is another class of water use that is not mentioned. That is the ownership of the navigable interstate and international water ways by the United States. In those circumstances the laws governing their use are federal.
There's a lot more to water law but those are the basics to get you started.
