Fresh water is needed to sustain healthy stock, healthy communities and healthy freshwater ecosystems. Freshwater catchments must be actively managed to maintain the high levels of water quality needed.
Landowners, developers, contractors and even gardeners need to consider entire catchments, rather than the immediate stretch of stream or river, to avoid degrading freshwater systems. It is important to understand thow
For instance, understanding that fish migrate the full length of waterways is fundamental to improving freshwater habitats, as is how discharges onto land in catchments effects the water that accumulates at the bottom of the gully.
