Both Colorado and Wyoming have similar access laws on their streams and rivers. In both states, the landowners? property rights include the river bed. If a particular landowner has property bordering only one side of the river/stream, their property extends to the middle. You may float over the property, but you cannot touch the bottom.
In Colorado in the last few years there has been an attempt by landowners to have legislation passed that would restrict the right to float through any private water, and I expect them to continue their efforts.
As kengore stated, "Land owners sometimes string barbed wires across sections of the river to keep out trespassing boaters. The legal system has supported this practice, inspite of the danger it poses to boaters," and there are currently a couple of cases pending where a national alliance of commercial rafters have brought suit on behalf of rafters that have been arrested for trespass. If things go as normal in the state, the suits wil never get to court, as the landowners do not want a review of river access by the states high court. Instead they will drag the suit out over a long period of time forcing the accused to spend time and money on lawyers, etc. Just before the case goes to court, the trespass charge will be dropped.
In Colorado (not sure about Wyoming) a landowner does not have to post their property; it's your responsibility to know what is private and what is public.
There's an old saying in Colorado and Wyoming, "Whiskies for drinking, waters for fighting."
