Acceler8 UpdateC-44 Project Objectives

• To provide flow attenuation and improved water
  quality to the St. Lucie Estuary, as well as
  water supply benefits.
• To capture and treat via sedimentation and
  natural transformation of nutrients the local
  runoff from the C-44 Basin and return it to the
  C-44 Canal.

Future Site of Intake Canal for C-44 Project
(Currently TIWCD Irrigation Pump Station)
Water would be conveyed from the C-44 Canal north
to the Project Pump Station, TIWCD Pump Station
would be removed and canal widened and deepened.

C-23 Diversion Canal

• The C-23 Canal is an artificial connection into
  the confluence of the North and South Forks of
  the St. Lucie River. It has increased the surface
  water flows within this area of the St. Lucie
  Estuary from a historic level.
• IRL-S PIR recommends diversion of 250 cfs from
  C-23 to the C-44 Project.
• C-23 Potential Diversion Routes
• Florida Power Light (FPL) Easement
• FCD (Flood Control District) Easement
• New Route east of FPL Easement
• Surface Flow Across Allapattah
