lmyers, thank you very much for that letter, very informative. Here is some more information I think might help people understand the idea of a, "river as a highway." True that there is very little state legislation on the matter, but there is no need for any. The United States Code states that:
-CITE-
33 USC Sec. 10 01/05/2009
-EXPCITE-
TITLE 33 - NAVIGATION AND NAVIGABLE WATERS
CHAPTER 1 - NAVIGABLE WATERS GENERALLY
SUBCHAPTER I - GENERAL PROVISIONS
-HEAD-
Sec. 10. Waters in Louisiana Purchase as public highways
-STATUTE-
All the navigable rivers and waters in the former Territories of
Orleans and Louisiana shall be and forever remain public highways.
-SOURCE-
(R.S. Sec. 5251.)
-COD-
CODIFICATION
R.S. Sec. 5251 derived from act Mar. 3, 1811, ch. 46, Sec. 12, 2
Stat. 606.
-End-

Unfortunately, I think that the Taylor River is about 10 miles outside the boundary of the Louisiana Purchase, but I'll keep looking in the federal code for applicable law.
