Z, That's a dry part of NM. You have the Pecos river west of it at Ft. Sumner. I lived in Hobbs, NM which is a way south of Clovis. Most of my fishing was in stock ponds and man made lakes put in by the towns for recreation. They are stocked regularly with catfish, bass and trout, depending on the time of year. As far as a rod weight I'd agree with Lotech. a 5 wt oughtta hold anything hooked up around there. I have hooked some really large gar and carp in the Pecos that might give a good bend to a 5wt but they're rarely that big.
My daughter lives in Levelland, TX just a little east of clovis. They go to Carlsbad, NM to play on the Pecos, or Ruidoso to fish for trout.
Good luck to your daughter. Jim
