Lake of Egypt

Lake of Egypt 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 Lake of Egypt rather than just read about it. In short: Lake of Egypt is a reservoir in the Little Egypt region of the U.S. state of Illinois. It is located six miles (10 km) south of Marion, Illinois and covers 2,300 acres (9 km²) with 90 miles (140 km) of shoreline.

Key takeaways

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

Reference excerpt

Lake of Egypt is a reservoir in the Little Egypt region of the U.S. state of Illinois. It is located six miles (10 km) south of Marion, Illinois and covers 2,300 acres (9 km²) with 90 miles (140 km) of shoreline. The lake has an average depth of 18 feet (5.5 m) with a maximum depth of 52 feet (16 m) . The lake is owned by the Southern Illinois Power Cooperative (SIPC), who created the impoundment in 1962, by damming the South fork of the Saline River, to supply cooling water for a coal-burning electric power plant. As a privately owned lake, it is subject to regulation by its owners and the state. Terms of use from the SIPC are in the "Official Lake of Egypt Rules and Regulations". Public access is allowed as are all size boat motors. Waterskiing and jet skis are also permitted in most of the lake. Fishing includes Bluegill, Largemouth Bass, Channel Catfish, Striped Bass, and Crappie. Camping at the lake is allowed at Buck Ridge Campground, part of the Shawnee National Forest. Each neighborhood on the lake has individual subdivisions (list of Lake of Egypt subdivisions Archived July 28, 2019, at the Wayback Machine) as well as the non-for-profit Lake of Egypt Association of Property Owners (LEAPO)

History Lake of Egypt was founded by Southern Illinois Power Cooperative (SIPC) to supply cooling water to their newly constructed coal burning power plant. The lake was created in 1962 by damming the south fork of the Saline River. The name was chosen from the nickname "Little Egypt" of Southern Illinois.

Worked examples

Example 1 — a first encounter with Lake of Egypt

Start with the simplest possible case. Write down what Lake of Egypt 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 Lake of Egypt 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 Lake of Egypt 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 Lake of Egypt

In research: Lake of Egypt 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 Lake of Egypt 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: Lake of Egypt is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 establishments in Illinois, Bodies of water of Johnson County, Illinois, Bodies of water of Williamson County, Illinois, so understanding it makes those chapters shorter.
In everyday life: Look for Lake of Egypt 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.
