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.

Maps
- Locus map – The Derwent estuary lies in the heart of the Hobart metropolitan area in southern Tasmania. It extends south from the rural town of New Norfolk to the Iron Pot lighthouse.
- Catchment map – The Derwent River winds its way from Lake St Clair through the catchment of forest and farms to the estuary and eventually the southern ocean.
- Map products – The Derwent Estuary Program Habitat Atlas includes a detailed GIS database, a compilation of coastal and subtidal mapping products, that can be accessed via the LIST.
