THREATENED FISH NOTES - OVENS RIVER: Most important river in
Victoria in regard to the survival of the Murray
Cod. Murray
Cod spawn almost as far up as Myrtleford
and the Ovens supplies recruitment for the Murray River as well. The
Ovens has no dams and is a river of extreme national significance. Trout
Cod are now being found in the Ovens
and may set up a self sustaining spawning population. Trout
Cod have been successfully stocked into
Ovens and upper Ovens, downstream of Myrtleford and going up the King
River - past Moyhu. All the tribs of the Ovens are important for native
fish including King, Buffalo and Buckland Rivers.

Hancock Watch site visit Mar 01: Extensive plantation taking in whole mountainside west of Myrtleford. Saw some evidence of logging carried some months earlier, however poor roading and steep gradiants made access into most of the plantation very difficult. Slopes ranges from steep to flat with little or no buffer zones on creeks evident from our brief visit. Most of the area not logged at the moment. Some native vegetation was evident on the plantation's western side. Site visit April 03: Noted recent logging in the Buffalo River catchment. Travelled through the plantation quickly. It was evident that steep slopes are apparent in this plantation giving the plantation a high conservation rating.

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.
Ovens River: The rivers all flow north, from heavily forested mountain country through excessive river flats to the Murray River. Murray cod populations close to the Murray River. Small river blackfish are common in many rivers, Macquarie Perch are still occasionally caught, and catches of golden perch are also being reported. Brown trout widely distributed through system with rainbow trout most abundant in upper reaches. Upstream from Myrtleford - Brown Trout to 1.3kg, some rainbow trout, small redfin and river blackfish.
Ovens River: Upstream from Myrtleford - Brown Trout to 1.3kg, some rainbow trout, small redfin and river blackfish.
Buffalo River - Below Lake Buffalo: Flows through grazing land. Popular stream section because it is readily accessible for much of its length. Water is used for irrigation, many of the deep holes are silting up. Contains brown trout and rainbow trout average 450g, maximum 1.3kg, also abundant redfin to 1.5kg, with occasional Macquarie Perch and Murray cod in the deeper pools. Stocked with juvenile Murray cod produced at Snobs Creek Hatchery.
