Lone Chimney Lake

Lone Chimney Lake is a engineering 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 Lone Chimney Lake rather than just read about it. In short: Lake Lone Chimney is a lake in Pawnee County, Oklahoma, east of Glencoe. It is owned by the Tri-County Development Authority.

Key takeaways

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

Reference excerpt

Lake Lone Chimney is a lake in Pawnee County, Oklahoma, east of Glencoe. It is owned by the Tri-County Development Authority. The lake, whose dam is also known as Lower Black Bear Creek Watershed Dam 19M, also extends into southern Payne County, Oklahoma. It was built in 1980 by the Tri-County Development Authority, Pawnee County Conservancy District and the Black Bear Conservancy District, assisted by the Oklahoma Conservation Commission and the USDA Natural Resources Conservation Service (NRCS) Watershed Protection and Flood Protection Program.

Purposes The dam was originally designed as part of a regional flood control project of the Lower Black Bear Creek Watershed, which included nineteen flood control dams. During the period of 1935-1954, before the dams were built, there had been seven major floods and 73 smaller floods. Before the Lone Chimney Lake was built, the design was altered to include 4,212 acre-feet (5,195,000 m3) of municipal water storage. The lake became the primary source of water for the small communities of Glencoe, Morrison, Yale, Blackburn, Skeede, Maramec and Terlton, Oklahoma. It is a secondary source for the larger towns of Cleveland and Pawnee, Oklahoma. According to one official website, the lake surface covers an area of 550 acres (2,200,000 m2). It has a shoreline of 17 miles (27 km). The Oklahoma Water Resources Board states that the shoreline is 18 miles (29 km), the normal surface area is 518 acres (2,100,000 m2), water capacity is 5,722 acre-feet (7,058,000 m3), and the normal elevation is 939 feet (286 m) above sea level.

Impact of drought Lone Chimney Lake has been plagued by drought-related problems for nearly a decade. It was nearly drained of municipal water in 2006, when high consumption caused the fixed intake valve to be above the lake's surface. It had to be replaced with a floating valve. The cost was about $19,000, but allowed the lake management to continue supplying its customers. The OWRB reported in December, 2011, that Lone Chimney again had to implement forced rationing because the reservoir was critically short of water. In June 2012, the City of Stillwater agreed to sell the Lone Chimney Water Association Up 2,000,000 US gallons (7,600 m3) of treated water per month for 30 years. In 2012, drought had severely damaged the capability to supply water to about 16,000 customers, because the lake level had dropped 11 feet (3.4 m) below normal. One of the water intakes was above the water level, while the other was partially above the line. By January 14, 2014, a television newscast reported that the lake was within a few weeks of running out of water. Record rainfall in May and early June, 2015, turned the water situation around at the lake, causing the water level to rise from 14 feet (4.3 m) below normal to 6 feet (1.8 m) below normal. However, the level must rise several more feet before the boat ramps can be used again. The fishing piers are still well above the water level and the land around them has been overgrown with brush that must be cleared. The Lone Chimney water treatment plant, closed several years ago, has not been restarted. That plant used a chloramine treatment process, whereas the Stillwater plant uses a chlorination process. The water treatment board must decide whether to convert the existing plant to achlorination, or to treat Stillwater's product to remove something compatible with the chloramine process.

Worked examples

Example 1 — a first encounter with Lone Chimney Lake

Start with the simplest possible case. Write down what Lone Chimney Lake claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Lone Chimney 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 Lone Chimney 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 Lone Chimney Lake

In research: Lone Chimney Lake appears in engineering 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 Lone Chimney 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: Lone Chimney Lake is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1980, Infrastructure in Oklahoma, Reservoirs in Oklahoma, so understanding it makes those chapters shorter.
In everyday life: Look for Lone Chimney 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.
