This document discusses a project called "Paddock to Reef" that involves integrated monitoring, modelling, and reporting from agricultural lands to the Great Barrier Reef. The project monitors water quality at various scales, from individual paddocks up to the reef ecosystem scale, to understand the impacts of agricultural management on pollutant loads. Field instruments are used to collect data on soil, surface runoff, and deep drainage water quality from sugarcane and banana sites. The current wet season has provided good sampling opportunities for the project.
