State of the Derwent Report

The State of the Derwent Report summarises five years of monitoring data and provides a comprehensive review of the health of the estuary. Topics covered include values and uses, pollution sources and loads, water quality, sediment quality, seafood safety, habitat and species, as well as recent management initiatives.

State of the Derwent Report Cards

Each year the State of the Derwent Report Card gives the community an idea of the Derwent estuary’s health. The annual Report Card summarises the monitoring data and other relevant information collected by the DEP and its partners (including Analytical Services Tasmania).
