Kangaroo Park plantation lies southeast of the Hotspur State Forest and was probably planted on ex-pasture sites. It has been surrounded by MIS bluegum plantations since 2000. Plantation likely to be located on groundwater recharge area for Port Campbell Limestone Aquifer, which provides irrigation water for the Heywood area..

THREATENED FISH NOTES - GLENAULIN CREEK/CRAWFORD RIVER: Only known habitat for FFG listed Ewens Pygmy Perch in Victoria. Yarra Pygmy Perch also found here.

Ewens Pygmy Perch

Plantation Catchment: Northern aspect meets Hotspur State Forest. Plantation located on Deep Creek and trib of Deep Creek. 1km upstream of Crawford River/Lake Crawford/Glenelg River.

Catchment Managment Authority: Glenelg-Hopkins Catchment Management Authority.

Hancock Watch Site visit Jan 01: Entire area a pine plantation on relatively flat land. Did not assess buffer zones on trib of Crawford River.

Crawford River: Flows through forest and grazing land, mud bottom. Contains mostly redfin, river blackfish, eels and abundant spiny freshwater crayfish, and tench. Last stocked with trout by Department in 1978. Currently no stocking with any species as stream tribuataries contain variegated pigmy perch, which is a species listed under the Flora and Fauna Guarantee Act 1988 as requiring protection.

According to current records, the Variegated Pygmy Perch is restricted to south-western Victoria and adjacent areas of south eastern South Australia. Despite intensive collecting efforts between 1983 and 1985, the species was found at only two localities; Glenaulin Creek (the type locality) at Winnap, Victoria, and Ewen's Ponds in South Australia (Kuiter & Allen 1986).

A 1990 survey of the waters in the Crawford River and Glenaulin Creek area undertaken by the then Department of Conservation and Environment identified several locations where the species exists in tributaries of the Crawford River and Glenelg River. Three locations were in Glenaulin Creek, near the location previously surveyed by Kuiter and Allen. It also appears that the population has returned to a healthy state in the streams feeding Ewen's Ponds.

"Groundwater: "In south-western Victoria the Otway Basin stretches from the South Australian border almost to the west of Geelong. It contains older sediments of Upper Cretaceous and Lower Tertiary age, up to 2000 m in thickness. These include four sand aquifers and two limestone aquifers. The sand aquifers of the Wangerrip Group are confined over most of the Basin and their recharge zones are located on the margins of the Otway Range in the east and the Merino Tablelands in the West. The groundwater moves towards the coast, increasing in salinity along its floorpath . . ." p268 State of the Environment Report 1988 Victoria's Inland Waters. Office of the Commissioner for the Environment.

"Shallow aquifers in the Glenelg River Basin occur in four main geologic units. Extending from the north-east of the Basin is a fractured rock basement aquifer composed of folded sediment, metamorphics and granite. In the north-east and also in the vicinity of the confluence of the Glenelg and Wannon Rivers, the basement aquifer is overlain by alluvial aquifers from the Quaternary period. The third unit is a Newer Volcanic aquifer which lies along much of the Basin's southern boundary, particularly in the east. This fractured rock aquifer is composed of basalt, scoria and tuff. The fourth unit is composed of dune sand and beach deposits extending from the south-west corner of the Basin up to the western boundary and along the northern boundary. It is known as the Bridgewater formation.

A deep aquifer system exists in the south-west of the Basin and extends to the top of the western boundary and half-way across the southern boundary. This sand aquifer, which is significant as a water source, occurs within the Wangerrip Group.

Generally, groundwater quality in the Basin decreases towards the north where it is saline. A large reserve of fresh water is held in the north-east corner of the catchment and in the south-west the water is of marginal quality . . ." p295 Water Victoria A Resource Handbook - Department of Water Resources Victoria 1989.
