- HWS2018 Habitat suitability modelling results for FishData describes habitat suitability modelling (HSM) results for fish in streams. The data was developed by University of Melbourne through the Melbourne Waterways Research Practice Partnership as part of the development of Melbourne Water’s Healthy Waterways Strategy 2018 (HWS2018). Analysis has been undertaken across the Melbourne Water operating region, where the operating region has been divided into 16,346 sub-catchments. Of these 16,346 subcatchments, 8233 contain Melbourne Water waterways. The results are presented for each of these 8233 reaches for these HWS scenarios:Current: habitat suitability for fish under current conditions (i.e. 2014).Current trajectory: habitat suitability for fish under urbanisation and climate change scenarios if current management approaches continue. Target trajectory: habitat suitability for fish given urbanisation and climate change (as for current trajectory), together with (a) delivery of performance objectives of the Healthy Waterways Strategy and (b) achievement of environmental condition scores as described in the Catchment Programs of the Healthy Waterways Strategy.Results are presented as:Stacked probabilities, i.e. habitat suitability all 13 native fished species added together. These stacked probability values were used in the HWS to provide a fish value score each reach and sub-catchments.Results are also provided for all 22 fish species. Presentation of habitat suitabilty model results for fish from the Healthy Waterways Strategy 2018.Habitat Suitability Model results have been thoroughly reviewed and are considered fit for purpose (i.e. for waterway planning). This data set covers the entire Melbourne Water region with the exception of very small areas close to Port Phillip Bay or Western Port. For example, there are small areas of French Island which are not captured.This data set was created using: 1. Streams dataset for the Healthy Waterways Strategy 2018 (developed by GraceGIS using Melbourne Water layers as inputs), and 2. Results from Habitat Suitability Modelling for the Healthy Waterways Strategy 2018. Further reading: Chee et al.

- HWS2018 Stormwater Priority AreasThis layer describes the stormwater priority areas for Melbourne Water’s Healthy Waterways Strategy 2018 (HWS2018). Stormwater priority areas were determined by a combination of decision support tools and the co-design process. The decision support tool used was Zonation, which prioritised management actions across the region with the objective of improving instream habitat suitability for platypus, fish and macroinvertebrates. The stormwater priority area polygons were created by merging sub-catchments from University of Melbourne’s subc layer, i.e. the network of sub-catchments used for assessing attenuated imperviousness and for habitat suitability modelling. Primary purpose for this data is identifying stormwater priority areas of Melbourne Water's Healthy Waterways Strategy 2018. This dataset covers the Greater Melbourne region with the stormwater priority areas presented in this dataset aligning with the priorities of the Melbourne Water Healthy Waterways Strategy 2018. However, it is important to note that stormwater management activities require additional judgement to consider whether areas beyond (e.g. upstream) of the priority areas identified will also require treatment to achieve the desired waterway health outcomes.The harvesting and infiltration targets presented in this dataset provide an estimate of what is required to achieve stormwater disconnection and recreation of the natural hydrology. However, is should be noted that these values are approximate only and do not replace site-specific investigations. The values have been calculated in reference to Walsh et al. 2012 , who presented target ranges for infiltration and harvesting required to achieve urban stormwater disconnection (i.e. re-creation of forested/vegetated hydrology). The values presented are the average of the ranges estimated by Walsh et al. 2012. These values do not replace a detailed site investigation. Site-specific factors (soil type, topography, geology and other hydrological features of the catchment) will influence the appropriate targets for a site.For further reading on the prioritisation process see:Chee et al. (in development), Habitat Suitability Models, Scenarios and Quantitative Action Prioritisation (using Zonation) for Melbourne Water’s Healthy Waterways Strategy: A Resource Document, University of Melbourne and Melbourne Water for Melbourne Waterways Research Practice PartnershipMelbourne Water (in development), Healthy Waterways Strategy Resource Document. Each priority area contains targets for harvesting and infiltration. Achievement of these targets is required to achieve stormwater disconnection. These targets are presented in two ways: per impervious hectare, and total volume to full urban development (i.e. complete urban development to the urban growth boundary). It should be noted that these targets are approximate values only and do not replace site-specific studies. See notes above about how target values were selected.For further reading, see: Walsh, C.

- HWS2018 Subcatchment BoundariesAs part of the Healthy Waterways Strategy 2018 (HWS2018) the Melbourne Water operating region was split into a series of sub-regions. This includes 5 catchments, and 69 sub-catchments. The boundaries of each region generally follow catchment boundaries. There are two separate spatial scales:- Catchments (5 regions: Werribee, Maribyrnong, Yarra, Dandenong, Westernport) and Sub-catchments (69 polygons). This dataset is an update to the Regional River Health Strategy (RRHS) Management Units layer created in 2008. Primary purpose of this data is for reporting of targets, performance objectives, conditions, values etc. relating to the Healthy Waterways Strategy.The sub-catchments in this dataset are an update of the "management units" developed for the Regional River Health Strategy in 2008. This dataset was created by merging sub-catchments from the University of Melbourne sub-catchments layer, commonly referred to as the DCI layer (where DCI refers to Directly Connected Imperviousness). The catchment polygons in this layer are similar to, but not exactly the same as those in the DCI layer currently used internally at Melbourne Water - The internally used layer has 15,901 polygon catchments, whilst the layer used to create this dataset has 16,346 polygon catchments. The Melbourne Water internal dataset will shortly be updated to align.NOTE: Whilst every effort has been taken in collecting, validating and providing the attached data, Melbourne Water Corporation makes no representations or guarantees as to the accuracy or completeness of this data.
