First plantation in Victoria to trial use of Hexazinone in 1978
Proclaimed Water Catchment Area: This plantation area is located in the Ovens River (Wangaratta) Water Supply Catchment.
Pesticides Review Committee Meeting #144 15/12/78. Letter sent from Forests Commission Victoria. "Approval sought to conduct aerial spraying to evaluate effectiveness of Velpar (active ingredient Hexazinone) for controlling woody weeds such as wattles and eucalypts in newly established pine plantations. The experiment is to be conducted in co-operation with DuPont (Australia) in the Myrtleford Forest District during mid November 1978... Water for domestic use is irregularly pumped from Emu Creek approximately 2.5km below the spray area..."

p11 Central Region To the north and east of the Eastern Boundary Fault lies an extenisive area of mountainous terrain composed of Ordovician sandstones and mudstones that are less resistant to erosion than the rocks of the south-western region. The drainage pattern is dendritic and the streams are seperated by sharp ridges and spurs. The mountains to the south of Mount Buffalo are typical of this region, which extends east to Mount Beauty and north to Myrtleford.
In the north-west around Moyhu and Bobinalwarral the ridges of Ordovician sediments become buried beneath the alluvial deposits of the riverine plain. Within the region, exposures of granitic rocks have intruded into the surrounding Ordovician sediments. Intense heat associated with the intrusions has altered (or metamorphosed) the adjacent sedimentary rocks. The granite outcrops at Mount Buffalo and Mount Emu are extremely resistant, while the surrounding sedimentary rocks which are less resistant have been deeply dissected.
In contrast, the granite in the Pinnacles area to the east of Myrtleford
is more susceptible to weathering and erosion and as a consequence the
terrain in this area is more subdued. A ridge of metamorphic rocks borders
Happy Valley to the east of Myrtleford. Friable reddish and brownish
gradational soils occur on the Ordovician sediments of this region,
while the granitic rocks of Buffalo Plateau and Mount Emu exhibit a
variety of soil types. Stony loams are characteristic of rocky outcrops
while poorly drained sites contain organic loams and peats. Sandy loams
and friable gradational soils are found on the lower slopes of these
intrusions. The less resistant granitic rocks at the Pinnacles and Abbeyard
carry a variety of gradational soils on the upper slopes and a range
of duplex soils at lower elevations. The gradational soils are suitable
for softwoods, but the poorly drained duplex soils are not.
