The Huerfano River is a tributary of the Arkansas River, located in south-central Colorado. The river is approximately 70 miles long and has a drainage area of 1,470 square miles. Historically, the river was used by Native American tribes for hunting and fishing. In the early 20th century, the river was dammed to provide irrigation for agriculture. The Huerfano River Watershed Project was established in 1965 to address erosion and water quality issues. Specific reservoirs and dams on the river include Huerfano Lake, Huerfano Valley, and the Huerfano-Cucharas Project. The river supports recreational activities such as fishing, kayaking, and camping. It is also used for agriculture, providing irrigation for crops such as alfalfa, corn, and wheat.
