LAKE Eildon is one of Australia's most celebrated freshwater fishing destinations.

Known for its abundance of brown and rainbow trout, the history of these fish in the lake is a fascinating tale of introduction, adaptation, and management.

The story of trout in Australia began in the mid-19th century, when European settlers sought to recreate the fishing opportunities they had enjoyed in their homelands.

Trout, prized for their sporting qualities and culinary value, were deemed ideal for Australian waters.

In 1864, the first successful hatching of brown trout (Salmo trutta) in Tasmania marked the beginning of trout acclimatisation in Australia.

Shortly thereafter, rainbow trout (Oncorhynchus mykiss), native to North America, were also introduced.

By the early 20th century, trout stocking efforts spread to Victoria.

Initially, the Victorian Fisheries Department focused on rivers and smaller reservoirs, but by the mid-1900s, larger water storage projects like Lake Eildon became key stocking sites.

Lake Eildon was created in 1929 with the completion of the Sugarloaf Dam and later expanded in the 1950s.

As the lake grew, it became an ideal habitat for trout due to its cool, deep waters and proximity to feeder rivers such as the Goulburn, Delatite, and Jamieson, which provide excellent spawning grounds and natural food sources like insects, crustaceans, and smaller fish.

Trout were first released into Lake Eildon shortly after its initial construction.

Brown trout, with their preference for cooler waters and natural predatory instincts, adapted well to the lake's environment.

Rainbow trout followed, favoured for their resilience and rapid growth rates.

Over time, these species established self-sustaining populations, supported by both natural reproduction and ongoing stocking efforts.

The management of trout in Lake Eildon has evolved significantly.

Fisheries Victoria (now part of the Victorian Fisheries Authority, VFA) began regular stocking programs in the mid-20th century to enhance recreational fishing opportunities.

Today, these programs remain a cornerstone of Lake Eildon’s status as a premier fishing destination.

The lake is stocked annually with tens of thousands of brown and rainbow trout fingerlings, along with other species such as Murray cod and golden perch.

This is supported by initiatives like the "Target One Million" campaign, which aims to boost fishing participation and sustainably manage fish populations.

Trout have become deeply ingrained in the culture of Lake Eildon.

The lake hosts numerous fishing competitions and draws anglers from across Australia, eager to experience the thrill of catching these prized fish amidst the stunning backdrop of Victoria's High Country.

This enduring legacy ensures that trout will remain a central part of Lake Eildon’s history and allure for generations to come.
