CYWP 2025-2026 Wet Season Monitoring Highlights – Part 2
2025-26 has been a massive wet season! Here are some more highlights from the Eastern Cape York Sediment Loads Monitoring Project.
🚣The River Water Quality (Sediment Loads) Monitoring field teams (CYWP and Traditional Owner partners) have braved the elements to collect flood samples and maintain continuous dataloggers across the Annan, Endeavour, Starcke, Normanby, and Pascoe rivers. The goal is to estimate annual loads of sediment (dirt) flowing out to the Reef from these rivers.
🌧 The largest flood event of the 2025-26 wet season for the Annan-Endeavour and Normanby catchments occurred in early March, followed by Cyclone Narelle around ten days later. These events inundated the lower Normanby catchment for weeks and created a massive floodwater plume in Princess Charlotte Bay that extended to the outer-reef and more than 100km to the north. Check out these NASA satellite images of the Normanby in March!
🧪Sadly, the flooding in March also damaged our equipment. The Scrubby Creek (upper Annan) dataloggers disappeared along with the tree they were attached to. The Battlecamp and Kalpower Xing (Normanby) dataloggers also experienced damage and loss of data. Along with malfunctioning Qld State river gauges, this will make it very difficult to estimate the flood magnitude and sediment loads flowing to Princess Charlotte Bay over this extreme wet season. Extremely disappointing!
However, we’ve still managed to gather plenty of data from these catchments and will continue to analyse the data and report on our findings from this exceptionally soggy year.
