§ 04Field notesMississippi

Where it is

Ross R Barnett Reservoir stretches to about 25,348 acres in Rankin County, Mississippi. 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. Warm water moves largemouth onto deeper structure and shade; the early and late hours are the better windows.

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

Winter. In cold water fish hold deep and inactive; ease off the pace and keep presentations quiet.

Key structure

  • Channel edges and the breaks beside them
  • Hard-bottom and rock transitions
  • Shoreline cover near quick depth changes
  • Creek and cove mouths that funnel fish and bait

The seasonal read outweighs any particular area here.

Forage

On Ross R Barnett Reservoir, schools of baitfish anchor the bite and largemouth stay close to them through the year.
