A monthlong fish kill stretching across the Neuse River was triggered by a rapid drop in water oxygen levels.
Environmental group Sound Rivers tracked the event from Bridgeton to Oriental, noting it lasted far longer than typical seasonal die-offs. Neuse Riverkeeper Samantha Krop said prolonged summer drought conditions severely stratified the river, trapping oxygen-depleted water at the bottom.
Recent cooler autumn nights forced that suffocating layer to the surface in a sudden aquatic turnover. While the shift primarily killed sensitive juvenile menhaden, officials are investigating whether nutrient pollution or toxic algal blooms extended the timeline.
