Dexter National Fish Hatchery (SNARRC)

A working recovery lab on Hatchery Road

On Hatchery Road at the east edge of Dexter, in the irrigated Pecos Valley of Chaves County, the Service runs its principal captive-propagation and fish-health campus for threatened and endangered warmwater fishes of the Southwest. Most people still say “Dexter hatchery.” The federal branding changed as the mission did: the campus shifted from stocking bass and catfish for weekend anglers to holding listed warmwater natives. On the order of one million fish from fourteen listed species are on station at any given time.

Three programs share the campus. One grows fish for reintroduction into wild rivers. Another works on genetics, spawning, and culture methods for species that do not breed on command. A third screens disease, runs diagnostics for other hatcheries and tribal and state partners, and supports the national wild-fish health survey. Laboratories and raceways beyond the public lobby are working culture and diagnostic spaces. Walk-in visitors get the lobby exhibits; anything deeper needs a pre-arranged tour.

How the mission shifted

The station opened under the White Act of 1930 as a National Fish Hatchery and began producing warmwater sport fish for the Southwest in 1932. The Endangered Species Act of 1973 rewrote the job description. By November 1974 staff were already holding six imperiled natives — two spring-endemic pupfishes (Comanche Springs and Leon Springs), three gambusias (Big Bend, Pecos, and Goodenough), and the fountain darter. Applied research became a formal program when the place was redesignated a Fish Technology Center in 1991. Disease specialists relocated here from Pinetop, Arizona, in 2005; the health unit later broadened beyond fish as salamanders, mussels, and other listed aquatic animals entered recovery plans.

Five taxa carry most of the annual production load. Bonytail exist here as the country’s only captive breeding stock — roughly 1,700 fish descended from the last ten wild individuals collected in 1981 — and produce animals for Colorado River reintroductions. Colorado pikeminnow (about 525 brood fish) support the San Juan River program. Rio Grande silvery minnow (about 12,000) feed augmentation in the Rio Grande. Razorback sucker (about 1,000) and woundfin (about 3,000) fill San Juan and Utah recovery commitments. In July 2024 the station received 559 wild woundfin flown in from partner agencies — a reminder that a refuge population keeps changing as wild fish move on and off station.

Getting there and what is open

From Roswell, take US-285 south, then NM-2 (Dexter/Hagerman) for about twelve miles into Dexter. Continue on NM-190 / Shawnee Road across the railroad tracks; about half a mile past the tracks, turn right into the station at 7116 Hatchery Road. From Artesia, US-285 north to NM-2 for about twenty-one miles, then local roads (Shoshoni Road and NM-190) into the same gate. The approach is paved county and state road the whole way; a passenger car is fine in normal weather. There is no long dirt approach and no fee booth.

The field station keeps weekday hours; check the Service’s visit page for the current schedule. The lobby holds species profiles and program exhibits and is the only interior space open without an appointment. Email or call ahead if a group needs a tour of culture rooms or labs — those areas stay closed to casual drop-ins so disease protocols and broodstock security are not compromised. Outside the interior fence, designated walk-in hunt units open seasonally under New Mexico Game and Fish rules; a valid state hunting license is required, and shooters must stay inside posted units and state shooting hours (half an hour before sunrise to sunset). Hunting access is a separate use of the property from station tours.

Trip pairing and expectations

Dexter is a working campus in a farming town. Most people fold a lobby stop into a wider Pecos Valley loop rather than making it the whole outing. Pair it with Bitter Lake National Wildlife Refuge north of Roswell for winter waterfowl and saline playas, Bottomless Lakes State Park east of Roswell for sinkhole lakes and short trails, or the historic districts and museums in Roswell if the hatchery lobby is closed for the weekend. Summer afternoons in the Pecos Valley routinely run hot and dry; plan outdoor time for morning and carry water even for a short lobby stop. There are no picnic grounds, nature store, or long trail system here — those sit at the nearby refuges. What you get is a clear look at how federal recovery works when a species has nowhere left but tanks and raceways, and a chance to see names that otherwise exist only as range maps.
