Lillydale Lake

Lillydale Lake is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lillydale Lake rather than just read about it. In short: The Lillydale Lake is a reservoir, artificial lake, and constructed wetlands created by an earth-filled embankment dam across the Olinda Creek, located in Lilydale, approximately 40 kilometres (25 mi) to the east of the Melbourne central business district, in Victoria, Australia. Following flooding of the Yarra Valley in 1984, the 28-hectare (69-acre) reservoir was created in 1990 to assist with flood mitigation.

Key takeaways

Lillydale Lake belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lillydale Lake to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lillydale Lake from memory before moving on to harder problems.

Reference excerpt

The Lillydale Lake is a reservoir, artificial lake, and constructed wetlands created by an earth-filled embankment dam across the Olinda Creek, located in Lilydale, approximately 40 kilometres (25 mi) to the east of the Melbourne central business district, in Victoria, Australia. Following flooding of the Yarra Valley in 1984, the 28-hectare (69-acre) reservoir was created in 1990 to assist with flood mitigation. Surrounding the reservoir is the Lillydale Lake Park, a 100-hectare (250-acre) urban park with extensive recreational facilities. The reservoir and wetlands are managed by Melbourne Water and the park is managed by the Yarra Ranges Council since 1990.

Overview Since settlement in the 19th century, low-lying areas of Lilydale were susceptible to flooding from the Olinda Creek. In 1969, the local council proposed a 65-hectare (160-acre) urban park, followed by several more proposals. However, due to a lack of funds, the proposals did not proceed. Following floods of the Yarra Valley in September 1984, construction of the lake was proposed to prevent future flooding and provide recreational facilities. The 440-metre-long (1,440 ft) earth-filled dam wall was built between 1988 and 1990 and created a resultant 28-hectare (69-acre) reservoir. The ruins of the 1850s Cashin's flour mill are situated at the northern end of the dam wall. The 100-hectare (250-acre) urban park was officially opened to the public on 7 July 1990. There are over 10 kilometres (6.2 mi) of shared trails, a community room and meeting facilities, a monster playground, toilets, barbecues and a picnic area. A boat launching ramp provides for non-powered boating. There are also two off-leash dog exercise areas.

Worked examples

Example 1 — a first encounter with Lillydale Lake

Start with the simplest possible case. Write down what Lillydale Lake claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lillydale Lake before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lillydale Lake ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lillydale Lake

In research: Lillydale Lake appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lillydale Lake in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lillydale Lake is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990 establishments in Australia, Constructed wetlands, Dams completed in 1990, so understanding it makes those chapters shorter.
In everyday life: Look for Lillydale Lake outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
