The Barataria Bay dolphin population was heavily impacted by the 2010 Deepwater Horizon (DWH) oil spill, which released an estimated 168 million gallons of oil into the Gulf of Mexico over 87 days. The oil contaminated surface waters and nearshore habitats hundreds of miles away from the wellhead, including Barataria Bay.

2022年10月18日 · Barataria Bay stock of bottlenose dolphins experienced significant mortality due to the DWH oil spill, with an estimated 45 percent reduction in population size relative to its pre-spill baseline (Schwacke et al. 2022). The most recent abundance estimate for the Barataria Bay stock is 2,071

2021年3月23日 · Update: Subsequent to the webinar, the Commission requested additional analyses on the potential effects of the proposed Mid-Barataria Sediment Diversion project in Barataria Bay, Louisiana, on recovery of the Barataria Bay stock of common bottlenose dolphins, and how the project might delay the stock’s recovery from the effects of the 2010 ...

Final Environmental Impact Statement for the proposed Mid-Barataria Sediment Diversion project in Barataria Bay, Louisiana. View Letter US Army Corps of Engineers and Louisiana Deepwater Horizon Trustee Implementation Group

Scientists estimate that the Barataria Bay dolphin population has declined by about 45 percent due to effects of exposure to oil from the 2010 Deepwater Horizon oil spill. Projections show the population is now threatened with extinction from operation of the Mid-Barataria Sediment Diversion Project, which will divert large amounts of fresh ...

presentations made by Drs. Schwacke and Garrison on the status and health of the Barataria Bay (BB) stock of common bottlenose dolphins and the potential effects of the Mid-Barataria Sediment Diversion (MBSD) on that dolphin stock. The BB stock of bottlenose dolphins experienced significant mortality from the 2010 Deepwater Horizon (DWH) oil spill.

Low-salinity conditions in mid-Barataria Bay also would affect the distribution of dolphin prey species, including spotted sea trout (de Mutsert et al. 2017). The LA TIG acknowledged potential effects on prey species in the draft SRP/EA but stated that prey species populations are expected to relocate to appropriate habitat.
