CYWP members undertake marine water quality monitoring across 4 Eastern Cape York sub-regions as part of the Great Barrier Reef Marine Park Authority's Marine Monitoring Programme.
Howley Environmental Consulting, Yintinga Aboriginal Corporation, Yuku Baja Muliku Land and Sea Rangers, and Kuku Yau rangers monitor water quality along river to reef transects in the following sub-regions: Annan-Endeavour, Normanby -Kennedy, Stewart and Pascoe Rivers.
Samples are collected 5 times per year along each transect during ambient conditions, with additional monitoring occurring during flood events.
