Note: Map includes all park maintained channels, including the 32 new corridors (which do not currently appear on nautical charts). Boaters are required to use standard and electronic navigation charts, and adhere to regulations of all newly-installed aids-to-navigation as posted.

Work was performed by a contractor in consultation with park staff. Funding was through the NPS and generous donations to the South Florida National Parks Trust from Yamaha and the American Sportfishing Association.

Boaters should be aware there are important changes to existing channels as part of this project:
  1. Twisty-mile Channel is now an idle-speed corridor, and adjacent area a pole/troll zone;
  2. Dump Key Channel: a new corridor has been installed just south of the original channel; later this year the original channel will be eliminated and be part of a pole/troll zone;
  3. North Jimmy Channel: a new corridor has been installed just north of the original channel; later this year the original channel will be eliminated and be part of a pole/troll zone;
  4. Pollock Key Channel and Bob Allen South Cut: an alternative on-plane corridor has been installed (called Bob Allen Pass) to provide access across this area and better protect resources; later this year the markers at these two short cuts will be removed and the areas will be part of pole/troll zones.
This project is a key component of the integrated GMP implementation strategy to enhance protection and enjoyment of the park’s marine areas. The Joe Bay/Snag Bay area was opened to public use for the first time in over 30 years in November 2016, and several other related GMP projects are expected to be completed this year:
  • Launch of the park’s boater education and permit program;
  • Availability of electronic navigation products (by major GPS companies, and a park boating app);
  • An Everglades National Park marine waters boating guide, developed in collaboration with the Florida Fish & Wildlife Conservation Commission.
