The upper Colorado stretch offers premier whitewater rafting through Brown's Canyon and the Royal Gorge, plus Gold Medal trout fishing. The 445-mile McClellan-Kerr Navigation System in Oklahoma and Arkansas supports commercial barge traffic and recreation. The river drains nearly 170,000 square miles across its course.
4.3(965)Pecos River
The Pecos River originates in north-central New Mexico and flows into Texas, emptying into the Rio Grande. Its headwaters are on the eastern slope of the Sangre de Cristo mountain range in Mora County north of Pecos, New Mexico, at an elevation of over 12,000 feet.
4.5(936)Red River
At 1,290 miles long, the Red River forms the Texas-Oklahoma boundary for approximately half its length, rising in eastern New Mexico and flowing southeast through Texas and Louisiana to the Mississippi. Denison Dam creates Lake Texoma — one of the largest U.S. reservoirs covering 89,000 acres and attracting 6 million visitors annually. The river's distinctive red color comes from sediment carried during flood periods, and ancient salt deposits from a 250-million-year-old sea give the water high mineral content.
