there is a list of navigable rivers on line somewhere. its federal thing. i used to have all that info after gettting run off a river bank by guy with a gun. its a great hole so i did my research and found it was navigable river and is "public domain to visible high water mark"! i went bank next weekend with my own carry gun. lol he tried the same thing. pulling back his vest to show his gun and tell me i couldnt fish there. i leaned back and showed my gun in my waist and said go rite ahead and call the law if you feel you have to. i said if you do ill get you ticketed for harassing a sportsman. lmao. never seen him again. anyhow all the laws and river list is on the net if you search. mot many navigable rivers to choose from in our state. water is still public though! just cant touch earth on non navigable waters.
