Will The Spillway’s River Water Hurt Fishing At The MRGO Long Rocks?

Is there so much river water that the 2019 spring run of speckled trout is negatively affected? Keep reading to learn more.


 I've been getting a lot of the same question lately:

"Will the Bonnet Carré Spillway opening affect the spring run of speckled trout at the MRGO Long Rocks?"

It's a good question, since a lot of us are depending on it for good trout action before they're all in harder-to-reach locations during the spawn.

This spring hot spot gives up easy limits of trout.

So what's the answer?

The answer is "probably not", when you consider:

  • How far river water from the spillway has to travel
  • How much of it will dissipate in saltier water
  • How unlikely it would be for it to flow in that direction

It's a loooong way for river water from the Bonnet Carré Spillway to affect the Long Rocks.

If the above graphic doesn't make it obvious, the real concern isn't the Bonnet Carré Spillway.

Instead, it's the much higher volume of river water much closer from the south.

All About Wind

Ultimately, how much that affects the MRGO Long Rocks will depend on what the wind does.

You need a great wind forecast to figure that out, and for that you should really check out Windfinder.

Tight lines, y'all!
