Nutrient Cycling in Lagoon of Islands,Tasmania: management to control eutrophication. Hydro Tasmania manages the Lagoon of Islands, a shallow freshwater lake on Tasmania's central plateau. The lagoon provides irrigation water and supports a significant recreational fishery. Over the last decade the lake has suffered increased nutrient enrichment, despite catchment management works to reduce external nutrient loads.

Hydro Tasmania manages the Lagoon of Islands, a shallow freshwater lake on Tasmania's central plateau. The lagoon provides irrigation water and supports a significant recreational fishery. Over the last decade the lake has suffered increased nutrient enrichment, despite catchment management works to reduce external nutrient loads.
Preliminary nutrient budgets suggest that a significant proportion of the water column nutrient load comes from the sediments, phytoplankton or macrophytes. Internal nutrient loads and loading mechanisms will be characterised. Cost effective strategies for their management will be developed utilising hydrological manipulation - a largely unexplored technique.Read moreRead less
Catchment-scale and riparian zone stormwater retention: can it restore stream hydrology? This project will test whether or not stormwater retention systems dispersed throughout a catchment can restore pre-development streamflows in peri-urban streams. It will provide a new model for the design of stormwater drainage systems which both protect aquatic ecosystems and reduce the demand for imported water in cities.
Restoration trajectories of stream ecosystems degraded by urban stormwater runoff: a large-scale experiment in urban hydrology and stream ecology. This project aims to assess innovative dispersed stormwater retention systems in catchments for protection and restoration of urban streams. It will improve the ecological condition of several study streams and provide scientific support for new policies and practices for urban water management, with multiple environmental and community benefits.
