When using any type of watercraft to access a body of water, it is important to follow all federal, state, and local rules and regulations. These rules and regulations include boat permitting and licensing, invasive species inspections and stamps, life jacket and PFD rules, motor size and horsepower restrictions, noise limitations, restrictions on personal watercraft, and many more. Visit the web link below for the most current rules and regulations for this body of water.
All persons fishing are subject to the license requirements listed below. Except for some “interstate waters” (Lake Tahoe, Topaz Lake, Lake Mead, Lake Mohave, Colorado River), anglers 12 years of age and older are required to obtain and possess a license or permit to fish. Nonresident anglers under 12 years of age are not required to have a license, but the number of fish taken by such nonresident anglers must not exceed 50 percent of the limit as provided by law. (For instance, if the limit is five, these young anglers may take only two fish.) Fishing license and permit requirements also apply to persons taking fish by means of spear or bow and arrow. (Refer to NRS 502.010)
This river has a variety of species and regulations, including potential floating and/or watercraft restrictions. Because this river is specially managed for species, seasons, angling methods, and watercraft, it is strongly encouraged you check all federal, state, and local regulations before fishing. Visit any of the links below, inquire locally, or contact a local fly shop to learn current regulations and restrictions.
In Nevada, navigable streams are those capable of being used or that have been used for commerce, such as floating logs to market. These streams can be floated, and probably fished, recreationally. The right to portage obstructions is undecided in Nevada. It is unlawful for any person to hunt, fish in non-navigable waters or trap upon land which is private property where the person has been warned by the owner or occupant of the property not to trespass.
