|If logging stopped, water yield would increase by 7-28%|
Independent research by Sinclair Knight Merz (SKM) released in January 2001, indicates that if logging in the Otway catchments was stopped, mean annual flow would increase by between 7% and 28%.
The Sinclair Knight Merz report concluded:
"However, should no disturbance occur to the forest cover, average annual yields will increase. For the West Barwon catchment, simulated yield was shown to have increased by up to 10% after 100 years. The corresponding increases in the Greater Arkins and St George catchments are 28% and 7% respectively."
