Georgia Code Title 44. Property § 44-8-5

(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.

(c) The General Assembly finds that the state procured ownership of all navigable stream beds within its jurisdiction upon statehood and, as sovereign, is trustee of its peoples' rights to use and enjoy all navigable streams capable of use for fishing, hunting, passage, navigation, commerce, and transportation, pursuant to the common law public trust doctrine. The state continues to hold title to all such stream beds, except where title in a private party originates from a valid Crown or state grant before 1863. The General Assembly further finds that the public retained the aforementioned rights under such doctrine even where private title to beds originates from a valid grant.
