Sill on Pearl River blocks sturgeon from moving upstream
Sill on Pearl River blocks Gulf sturgeon from spawning grounds.
Project designed a rock ramp to allow fish to move upstream.

Habitat: Spawning habitat of threatened Gulf sturgeon; habitat of 19 species of fish and other organisms that move within, to and from the Pearl River during their life cycles.

Species Benefiting From Restoration:

  • Alabama Shad
  • Atlantic needlefish
  • Gizzard shad
  • Gulf sturgeon
  • Hogchoker
  • Striped bass
  • Skipjack herring
  • Threadfin shad
  • American eel
  • Blacktail redhorse
  • Blue catfish
  • Channel catfish
  • Flathead catfish
  • Highfin carpsucker
  • Paddlefish
  • Pearl darter
  • Quillback
  • River redhorse
  • Southeastern blue sucker
  • Spotted sucker

Acreage Restored:

History: In order to maintain desired water levels for the Pearl River Navigation Canal in the 1950s, underwater concrete sills were constructed at the upstream end of the canal on the Pearl River and the downstream end on the Bogue Chitto River. The navigation canal now sits largely unused but sill prevents migratory species from passing upstream, especially during low water times.

Rationale for Project: The population depletion of the threatened species Gulf sturgeon is largely due to hydrologic modification to the rivers. In the Pearl River Basin, the sturgeon is prevented from accessing 80 percent of its historical spawning grounds by the combined effect of blockages by low water sills. If the effect of these blockages were removed or mitigated, the sturgeon would be able to access spawning grounds all the way to Jackson, Mississippi.
