Lake Lyndon B. Johnson

Lake Lyndon B. Johnson 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 Lyndon B. Johnson rather than just read about it. In short: Lake Lyndon B. Johnson (more commonly referred to as Lake LBJ and originally named Lake Granite Shoals) is a reservoir on the Colorado River in the Texas Hill Country about 45 miles northwest of Austin.

Key takeaways

Lake Lyndon B. Johnson 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 Lyndon B. Johnson to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lake Lyndon B. Johnson from memory before moving on to harder problems.

Reference excerpt

Lake Lyndon B. Johnson (more commonly referred to as Lake LBJ and originally named Lake Granite Shoals) is a reservoir on the Colorado River in the Texas Hill Country about 45 miles northwest of Austin. The reservoir was formed in 1950 by the construction of Granite Shoals Dam by the Lower Colorado River Authority (LCRA). The Colorado River and the Llano River meet in the northern portion of the lake at Kingsland.

Location and history

The towns of Granite Shoals, Kingsland, Horseshoe Bay, Highland Haven, and Sunrise Beach are located on the lake. The boundary line separating Burnet County and Llano County runs down the center of the lake. The lake was originally called Lake Granite Shoals. The dam would be renamed Wirtz Dam in 1952 for Alvin J. Wirtz, the first general counsel of the LCRA, and the lake was renamed to Lake Lyndon B. Johnson in 1965 in honor of US President Lyndon Baines Johnson. In addition to his work to enact the Rural Electrification Act that formed the basis for building the Texas Highland Lakes, President Johnson owned a ranch on the lake (which was separate and apart from the LBJ Ranch in Stonewall, Texas). He and Mrs. Johnson entertained national and foreign dignitaries on the lake during his vice presidency and presidency. The other reservoirs on the Colorado River are Lake Buchanan, Inks Lake, Lake Marble Falls, Lake Travis, Lake Austin, and Lady Bird Lake. Lake LBJ along with Inks Lake and Lake Marble Falls are pass-through lakes for Lake Buchanan and Lake Travis. There is no room in Lake LBJ for additional water storage, and water that comes in must go out. Therefore, Lake LBJ is at a near constant level, but the level can fluctuate, especially during a flood. The LCRA lowers the lake periodically for maintenance on Wirtz Dam and to allow landowners to remove sediment around their docks.

Fish and wildlife populations Lake LBJ has been stocked with several species of fish intended to improve the utility of the reservoir for recreational fishing. Fish present in Lake LBJ include largemouth bass, white bass, catfish, and crappie. Lake LBJ is one of the Highland Lakes infested with hydrilla, a non-native aquatic plant species, and the LCRA is undergoing treatment to eradicate the hydrilla.

Recreational uses

Most of the property bordering Lake LBJ is privately owned. The Nightengale Archaeological Center at Kingsland is a unique educational park operated by the Lower Colorado River Authority that is adjacent to Lake LBJ. The lake is also home to Camp Champions, the only summer camp with property on the lake. The popularity of Lake LBJ is largely due to its normally constant level water which provides ideal conditions for boating, water skiing, riding personal water craft and other water sports. Swimming in summer months is inadvisable due to the presence of the rare but deadly Naegleria fowleri.

Cooling water The lake provides cooling water for the Thomas C. Ferguson Power Plant that is located on its shores.

Worked examples

Example 1 — a first encounter with Lake Lyndon B. Johnson

Start with the simplest possible case. Write down what Lake Lyndon B. Johnson 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 Lyndon B. Johnson 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 Lyndon B. Johnson 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 Lyndon B. Johnson

In research: Lake Lyndon B. Johnson 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 Lyndon B. Johnson 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 Lyndon B. Johnson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 establishments in Texas, Bodies of water of Burnet County, Texas, Bodies of water of Llano County, Texas, so understanding it makes those chapters shorter.
In everyday life: Look for Lake Lyndon B. Johnson 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.
