New Orleans, LA – Louisiana’s impending coastal restoration project, the Mid-Barataria Sediment Diversion, has raised concerns about its potential impact on the local dolphin population. This has led to a ramp-up in rescue and monitoring initiatives.
Project Implications
To counteract wetland loss, the $3 billion project aims to divert sediment-rich Mississippi River water into the Barataria Basin. However, the resulting freshwater influx could lower the basin’s salinity levels, endangering the resident dolphins.
Dolphin Stranding Concerns
Historical data suggests that salinity fluctuations can lead to increased dolphin strandings. For instance, in 2019, many bottlenose dolphins were stranded along the Gulf Coast, a phenomenon attributed to low salinity levels from heavy rainfall and river water release.
The Dolphin Rescue Strategy
A three-phase rescue plan has been outlined:
- Preparation and Training (24 months): Workshops will focus on dolphin health, salinity effects, and basin biology. Various intervention strategies will be evaluated.
- Monitoring (up to 2 years post-completion): Dolphins will be observed to gauge the diversion’s impact.
- Intervention: Based on the data, interventions may range from herding dolphins away from low salinity zones to capturing and treating those in distress.
Future Measures
State officials are also considering alternative measures, such as designing projects that divert freshwater away from dolphin habitats or constructing protective berms.
Ensuring the well-being of the dolphin population is crucial. As Louisiana undertakes this significant coastal project, the safety of these marine mammals remains at the forefront. You can visit the original article here for more details.
