Be aware and for-warned on tresspassing.
You can travel any waterway, by means of water travel, as long as there is a public access or state owned property adjoined to that water.
However, as soon as you step out of the water, unto land, that is not state owned, you are tresspassing. Nobody can stake claim to land under waterways. However, any soil/land not in the actual water/H20 legally becomes the private property of the landowner, during high water or low water.
For the most part, farmers/land owners do not care if you fish these creeks or not. However the common courtesy of asking permission will go a long ways and save you a lot of foot travel.
Also, it does help knowing if there is a bull in the pasture with the cows.
Sometimes, people can be a bit rude about this and it can make for a humorous day watching them run like hell to get away from the raging bull!
