Leaky weir maintenance

Flow levels in Mulloon Creek have finally dropped enough for some much-needed maintenance of in-stream structures to take place. Three years of above average rainfall and high flow conditions has meant that some structures which needed some minor maintenance had to withstand the conditions until it was dry enough.

This picture shows a structure after some extra-large rock was placed on the ramp, which will hold the smaller rock in place the next time a big pulse comes through.

These leaky weirs have been installed as part of the award-winning, catchment-scale Mulloon Rehydration Initiative which aims to to rebuild the natural landscape function of the Mulloon catchment and boost its resilience to climatic extremes. This is resulting in more reliable stream flows, improved ecosystem functioning and enhanced agricultural productivity. The project spans 23,000 hectares and includes 23 landholders.

The Mulloon Rehydration Initiative is jointly funded through the Mulloon Institute and the Australian Government’s National Landcare Program and is supported by the NSW Government’s Environmental Trust.
