§ 04Field notesNew Mexico

Where it is

Caballo Reservoir sits in Sierra County, New Mexico, covering about 4,617 acres. Where the largemouth sit changes with the season, not the map.

Seasonal pattern

Spring. Warming water pulls largemouth toward shallow, protected areas where they stage and spawn; the quickest-warming pockets lead.

Summer. Heat pushes fish off the shallows toward depth and shade; work the cooler ends of the day.

Fall. As water cools, forage and bass return toward shallower water; movement is wide, so covering water pays.

Winter. Cold water settles fish deep and slow; patience and a subtle presentation are the more dependable choice.

Key structure

  • Creek and cove mouths that funnel fish and bait
  • Weed edges and the clean lines along them
  • Inside turns where a bank changes angle
  • Submerged wood, brush, and laydown cover

The calendar decides which of these is worth time on a given day.

Forage

Largemouth on Caballo Reservoir hunt baitfish and panfish along cover; forage and weather drive the day's bite.

Access

Public access points serve Caballo Reservoir; verify ramp conditions and lake levels before setting out.

Regulations

Check current state and local regulations before fishing; limits and seasons can change.
