The Arkansas River is one of the most diverse and productive fisheries in the United States, flowing approximately 1,469 miles from its headwaters in the Colorado Rockies through Kansas, Oklahoma, and Arkansas before joining the Mississippi River. This remarkable waterway descends nearly 10,000 feet in elevation throughout its journey, creating a variety of fishing environments from mountain freestone sections to warm-water flatland fisheries. The river offers tremendous fishing opportunities year-round, with sections designated as Gold Medal water in Colorado and productive fisheries throughout its course in the other states. Whether you're a fly angler seeking trout in the upper reaches or targeting catfish and bass in the lower sections, the Arkansas River provides exceptional angling experiences across its diverse ecosystems.

Colorado Stream Access Laws

With no clear test of navigability, no applicable statutes, and a tendency of courts to categorize all streams in Colorado as non-navigable, waterfront landowners' rights encompass the banks, beds, and waters of rivers. The public has no guaranteed recreation rights in non-navigable waters or their streambeds. CO Fishing Regulations: "It is illegal to go onto private land to fish without permission, including touching any part of private land by person or watercraft. Private land is not required to be posted or fenced. Trespassers may be suspended for up to 5 years."
