On This Water

Louisiana · Grand Isle / Barataria

Speckled trout should be the day — push Barataria and the bayside grass — trout first, reds on the drain later.

Louisiana’s inhabited barrier island. Caminada and Barataria, the state-park surf and pier, trout and reds in the bays. NOAA 8761724 sits on the island. Do not fish it like Venice — this is a bay-and-beach desk, not the birdfoot.

  • This brief is for 2026-04-21. No wind forecast that far out — score is tide, moon, and season. Not a copper day.

Why — and who

  • Tide is incoming (modeled — the NOAA gauge did not answer).
  • Waxing crescent moon — mid tide range. Marsh and passes usually want the extra current of a spring.
