Title 44, Chapter 8, Section 5
(a) As used in this chapter, the term "navigable stream" means a
stream which is capable of transporting boats loaded with freight in
the regular course of trade either for the whole or a part of the
year. The mere rafting of timber or the transporting of wood in
small boats shall not make a stream navigable.
(b) The rights of the owner of lands which are adjacent to navigable
streams extend to the low-water mark in the bed of the stream.
