§ 04Field notesLouisiana

Where it is

Lake Saint Catherine sits in Orleans Parish, Louisiana, covering about 6,689 acres. Cover, depth, and weather drive the day's lanes more than the shoreline.

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

Forage on Lake Saint Catherine pulls largemouth between cover and the open water that schools of bait drift through.

Access

Lake Saint Catherine has public access points; conditions and water levels change, so verify locally before launching.

Regulations

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