Lower Hawkesbury-Nepean River Nutrient Management Strategy

The Hawkesbury-Nepean River and its catchment provide drinking water, recreational opportunities, agricultural and fisheries produce, as well as tourism and mining resources for the Sydney Metropolitan area. It is also an important ecological asset adjoining the World Heritage listed Blue Mountains.

In recent years algal blooms and excessive aquatic weed growth have hampered recreation and commercial uses of the river and affected aquatic life. Elevated nutrient levels and reduced river flows are thought to be the two major factors contributing to stresses on the river.

In order to help address these challenges, the Lower Hawkesbury-Nepean River Nutrient Management Strategy has been developed with the aim of reducing nutrient loads from existing sources and limiting the growth in nutrient loads from changing land uses. It proposes to do this by providing an integrated and catchment wide framework to coordinate and guide action on managing nutrients in the lower Hawkesbury-Nepean from identified priority sources, including stormwater, wastewater and agricultural runoff.

The strategy highlights the many initiatives that are already under way to reduce nutrient loads in the lower Hawkesbury-Nepean catchment, including educational and compliance activities, extension programs, investment in capital projects, on-ground works, and partnership programs. It also identifies strategic priorities and new actions that will build on the work to date and reduce nutrient loads from identified priority sources.
