Results of the National Water Commission’s Framework for Assessment of River and Wetland Health for Furneaux SWMA

This page provides a summary of the results of the National Framework for the Assessment of River and Wetland Health (FARWH) for Furneaux water management area.

Table 1 Results of the National Framework for the Assessment of River and Wetland Health (FARWH) for Furneaux water management area

Component	Score	Notes
Biota	0.85	The Aquatic Biota Index provides a measure of the biological health of rivers using data on aquatic macroinvertebrates, native and exotic fish as presented in the Conservation of Freshwater Ecosystem Values Framework (CFEVF).
Catchment Disturbance	0.65	The Catchment Disturbance Index provides a measure of human caused changes that impact the river and wetland condition and the biota. For Tasmania the Catchment Disturbance Index is based the area of catchment land uses draining to a reach as presented in the CFEVF.
Hydrology Disturbance	1	The Hydrological Disturbance Index assesses the flow regimes change that result from river regulation and/or substantial flow diversion or extraction. For Tasmania the Hydrological Disturbance of rivers is based on the CFEVF data.
Physical Form		Physical Form was not presented for Tasmania because suitable data that met the requirements of the Framework for the Assessment of River and Wetland Health (FARWH) were not available.
Water Quality		Water quality assessment was not presented for Tasmania because suitable data meeting the needs of the FARWH were not available.
Fringing Zone	0.59	The Fringing Zone Index is a measure of the riparian vegetation condition as determined in the CFEVF.
Overall Score	0.72	The Overall Index for a Surface Water Management Area is a combination of the individual indices (Biota, Catchment Disturbance, Fringing Zone, and Hydrological Disturbance) to assess the overall health of the river. For Tasmania the indices are integrated at reaches using Euclidean Distance and weighted by reach length, then aggregated to give the overall Surface Water Management area score.

This page provides high level performance indicators of water management for the Furneaux surface water management area (SWMA) based on information provided by the government of Tasmania. It provides answers to a range of questions of relevance to the National Water Initiative (NWI), specifically in relation to:

Surface water management framework
Water resources caps
Surface water / groundwater interaction
Surface water sustainable yield
Environmental water requirements
Surface water diversions
Surface water entitlements
Protected terrestrial areas

Please note that a dash means that either the data was not available, not provided or that the question was not relevant for a particular area.
