§ 04Field notesNew Mexico

Where it is

Elephant Butte Reservoir sits in Sierra County, New Mexico, covering about 10,908 acres. Largemouth use the shallow cover and the deeper water as the calendar moves.

Seasonal pattern

Spring. Rising temperatures draw largemouth into shallow cover to stage and spawn; the protected, faster-warming water turns on first.

Summer. With the surface hot, largemouth favor deeper edges and shade, and the low-light hours carry the bite.

Fall. Falling water temperature draws bait and largemouth back shallow into a broad, roaming feed.

Winter. Largemouth go deep and sluggish in cold water, so a slow, methodical approach is the safer bet.

Key structure

  • Creek and cove mouths that funnel fish and bait
  • Flats sitting next to deeper water
  • Points where shallow water drops toward deeper water
  • Hard-bottom and rock transitions

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

Forage

Where the bait goes on Elephant Butte Reservoir, the largemouth follow — that is the read here.
