Rio Costilla Fishing Map – New Mexico

Fish smarter, not harder.

This detailed Rio Costilla Fishing Map was created by local anglers who know the river firsthand—because they’ve spent decades fishing, wading, and exploring one of northern New Mexico’s most remote and lightly pressured trout streams.

Covering the Rio Costilla from below Costilla Reservoir downstream to Amalia, this map clearly shows where you can legally access and fish the river through forested headwaters, meadow stretches, and valley water near town. Public lands and access points are presented in a clean, easy-to-read format designed for real use on the water.

Tailwater Section – Below Costilla Reservoir

This map includes detailed coverage of the Rio Costilla tailwater below Costilla Reservoir, where controlled releases create cold, consistent flows and excellent trout habitat. Access points, walk-in areas, and parking locations are clearly identified to help anglers navigate this secluded section efficiently and legally, especially where public and private lands intersect.

• Clearly marked public lands, including federal, state, county, and city ownership

• Public fishing access points along the Rio Costilla

• River miles, bridges, and key reference points
