79-725: Deep Eddy Pool is a historic man-made swimming pool in Austin , Texas . Deep Eddy is the oldest swimming pool in Texas and features a bathhouse built during the Depression era by the Works Progress Administration . The pool began as a swimming hole in the Colorado River , became a resort in the 1920s, and is today a popular swimming pool operated by the City of Austin. Deep Eddy began as
158-410: A redwood or simulated wood surround, and are termed "portable" as they may be placed on a patio rather than sunken into a permanent location. Some portable spas are shallow and narrow enough to fit sideways through a standard door and be used inside a room. Low power electric immersion heaters are common with home spas. Whirlpool tubs first became popular in the U.S. during the 1960s and 1970s. A spa
237-529: A swimming hole located along the banks of the Colorado River which flows through Austin. It takes its name from an eddy that was formed by a large limestone outcropping which once jutted out into the river. In 1902, siblings Mary and Henry Johnson established the Deep Eddy Bathing Beach on the property (which was owned by their father). At that time the property was located outside of Austin, but
316-401: A "wagon wheel, ringed with lights, suspended by chains." The men's and women's dressing rooms were located on either side of the entryway and were open to the elements. Initial plans called for the entire structure to be roofed, but the roofs over the dressing areas were removed from the plans when the project went overbudget. Using less space, the new bathhouse could accommodate more bathers than
395-460: A coin to be inserted in a slot, either as deposit or payment. There are usually showers – sometimes mandatory – before and/or after swimming. There are often also lifeguards to ensure the safety of users. Wading or paddling pools are shallow bodies of water intended for use by small children, usually in parks. Concrete wading pools come in many shapes, traditionally rectangle, square or circle. Some are filled and drained daily due to lack of
474-408: A concrete pool which opened during the summer of 1916. George Rowley, a partner of Eilers and a former movie theater owner from San Antonio , was hired to manage the business; he and his family moved into the caretaker's house on the property. A wooden bathhouse was built, as well as nineteen wooden rental cottages which replaced the campsites on the hill overlooking the pool. Under Rowley's management,
553-665: A custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool . Many health clubs , fitness centers , and private clubs have pools used mostly for exercise or recreation. It is common for municipalities of every size to provide pools for public use. Many of these municipal pools are outdoor pools but indoor pools can also be found in buildings such as natatoriums and leisure centers . Hotels may have pools available for their guests to use at their own leisure. Subdivisions and apartment complexes may also have pools for residents to use. Pools as

Educational facilities such as high schools and universities sometimes have pools for physical education classes, recreational activities, leisure, and competitive athletics such as swimming teams. Hot tubs and spas are pools filled with water that is heated and then used for relaxation or hydrotherapy . Specially designed swimming pools are also used for diving , water sports, and physical therapy , as well as for
711-416: A filter system. Staff chlorinate the water to ensure health and safety standards. The Fédération Internationale de la Natation (FINA, International Swimming Federation) sets standards for competition pools: 25 or 50 m (82 or 164 ft) long and at least 1.35 m (4.4 ft) deep. Competition pools are generally indoors and heated to enable their use all year round, and to more easily comply with
790-529: A floating raft in the river. The coffee was kept hot over a fire; club members had to tread water and drink coffee at the same time. The last swimmers managed to overturn the raft, to the amusement of 150 spectators. The Amateur Swimming Association was founded in 1869 in England, and the Oxford Swimming Club in 1909. The presence of indoor baths in the cobbled area of Merton Street might have persuaded

#1732868975833948-426: A larger leisure center or recreational complex. These centres often have more than one pool, such as an indoor heated pool, an outdoor ( chlorinated , saltwater or ozonated ) pool which may be heated or unheated, a shallower children's pool, and a paddling pool for toddlers and infants. There may also be a sauna and one or more hot tubs or spa pools (" jacuzzis "). Many upscale hotels and holiday resorts have
1027-410: A month after the purchase, a massive flood on the Colorado River destroyed the bathhouse and other improvements, and filled the pool with mud and debris. The Works Progress Administration and the city of Austin jointly funded the building of a new bathhouse, which was designed by Austin architects Dan Driscoll and Delmar Groos. The new bathhouse was a mixture of Moderne and Rustic architectural styles;
1106-514: A number of sporting events, including the Deep Eddy Mile swimming competition. Since the 1960s, two thirds of the original bathhouse had been closed to swimmers and put to various uses by the City of Austin. During this time, rather than enter through the original reception area, visitors entered around the side of the bathhouse and paid their fee at an exterior counter. From there they could use one of two dressing rooms which had been carved out of
1185-453: A physical disability) where gradual entry is useful. Indoor pools are located inside a building with a roof and are insulated by at least three walls. Built for year-round swimming or training, they are found in all climate types. Since the buildings around indoor pools are insulated, heat escapes much less, making it less expensive to heat indoor pools than outdoor pools (all of whose heat escapes). Architecturally, an indoor pool may look like
1264-681: A potential risk of underwater entrapment from the pump suction forces. However, commercial installations in many countries must comply with various safety standards which reduce this risk considerably. Home spas are a worldwide retail item in western countries since the 1980s, and are sold in dedicated spa stores, pool shops, department stores , the Internet, and catalog sales books. They are almost always made from heat-extruded acrylic sheet Perspex , often colored in marble look-alike patterns. They rarely exceed 6 m (65 sq ft) and are typically 1 m (3 ft 3 in) deep, restricted by
1343-414: A relatively simple, L-shaped, single story building of rough-hewn and locally quarried limestone. The "pagoda-like roof", consisting of three metal platforms of decreasing size topped with a twenty-foot spire, covered only the reception area at the intersection of the two wings where swimmers paid their entry fees. At the center of this area sat an octagonal wood and limestone ticket counter, and above it hung
1422-502: A second new one at 400 ft, and is not chlorinated. Water temperature varies between 68 and 75 °F (20 and 25 °C). The lap swimming pool is generally open during daylight hours all year, though hours are shortened during winter months. The lap and the wading pool are open from March 14 through October 31, 8:00am to 8:00pm. In summer months, the pool sponsors Splash Party Movie Nights, showing family films on an inflatable movie screen visible by swimmers and waders. The pool supports
1501-665: A similar level of protection for the children residing in or visiting the house, although many pool owners prefer the visual aspect of the pool in close proximity to their living areas, and will not provide this level of protection. There is no consensus between states or countries on the requirements to fence private swimming pools, and in many places they are not required at all, particularly in rural settings. Inexpensive temporary polyvinyl chloride pools can be bought in supermarkets and taken down after summer. They are used mostly outdoors in yards, are typically shallow, and often their sides are inflated with air to stay rigid. When finished,
1580-662: A swimming pool for use by their guests. If a pool is in a separate building, the building may be called a natatorium . The building may sometimes also have facilities for related activities, such as a diving tank. Larger pools sometimes have a diving board affixed at one edge above the water. Many public swimming pools are rectangles 25 m or 50 m long, but they can be any size and shape. There are also elaborate pools with artificial waterfalls , fountains, splash pads , wave machines, varying depths of water, bridges, and island bars. Some swimming facilities have lockers for clothing and other belongings. The lockers can require
1659-561: A water garden to be a part of the system, offer different aesthetic options and can support amphibious wildlife such as snails, frogs, and salamanders, and even small fish if desired. A zero-entry swimming pool , also called a beach entry swimming pool , has an edge or entry that gradually slopes from the deck into the water, becoming deeper with each step, in the manner of a natural beach. As there are no stairs or ladders to navigate, this type of entry assists older people, young children and people with accessibility problems (e.g., people with

If it is a public pool designed for diving, it may slope from 3.0 to 5.5 m (10 to 18 ft) in the deep end. A children's play pool may be from 0.3 to 1.2 m (1 to 4 ft) deep. Most public pools have differing depths to accommodate different swimmer requirements. In many jurisdictions, it
1817-723: Is a requirement to show the water depth with clearly marked depths affixed to the pool walls. Pools can be either indoors or outdoors. They can be of any size and shape, and inground or above ground. Most pools are permanent fixtures, while others are temporary, collapsible structures. Private pools are usually smaller than public pools, on average 3.7 m × 7.3 m (12 ft × 24 ft) to 6.1 m × 12.2 m (20 ft × 40 ft) whereas public pools usually start at 20 m (66 ft). Home pools can be permanently built-in, or be assembled above ground and disassembled after summer. Privately owned outdoor pools in backyards or gardens started to proliferate in
1896-468: Is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and may be found as a feature aboard ocean-liners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete , natural stone, metal, plastic, composite or fiberglass , and can be of
1975-444: Is a swimming pool which produces a visual effect of water extending to the horizon, vanishing, or extending to "infinity". Often, the water appears to fall into an ocean, lake, bay, or other similar body of water. The illusion is most effective whenever there is a significant change in elevation, though having a natural body of water on the horizon is not a limiting factor. Natural pools were developed in central and western Europe in
2054-402: Is also called a "jacuzzi" there, as the word became a generic after-plumbing component manufacturer; Jacuzzi introduced the "spa whirlpool" in 1968. Air bubbles may be introduced into the nozzles via an air-bleed venturi pump that combines cooler air with the incoming heated water to cool the pool if the temperature rises uncomfortably high. Some spas have a constant stream of bubbles fed via
2133-629: Is believed to be the oldest surviving swimming club in Britain. It was formed in 1844, in response to concerns over drownings in the River Medway , especially since would-be rescuers would often drown because they themselves could not swim to safety. The club used to swim in the River Medway, and would hold races, diving competitions and water polo matches. The South East Gazette July 1844 reported an aquatic breakfast party: coffee and biscuits were served on
2212-469: Is commonly used to accommodate water polo. USA Swimming (USA-S) swims in both metric and non-metric pools. However, the international standard is metres, and world records are only recognized when swum in 50 m pools (or 25 m for short course) but 25-yard pools are very common in the US. In general, the shorter the pool, the faster the time for the same distance, since the swimmer gains speed from pushing off

A plunge pool is a smaller, permanently installed swimming pool, with a maximum size of approximately 3 m × 6 m (10 ft × 20 ft). Construction methods for private pools vary greatly. The main types of in-ground pools are gunite shotcrete , concrete, vinyl -lined, and one-piece fiberglass shells. Many countries now have strict pool fencing requirements for private swimming pools, which require pool areas to be isolated so that unauthorized children younger than six years cannot enter. Many countries require

In 2012 the City of Austin rebuilt the pool due to stubborn leaks in the pool shell which had been patched repeatedly. Work crews poured a new bottom on both sides of the pool, and repaired small cracks and leaks. The pool's west end was smoothed and lengthened and a beach-type (zero-depth) entry was created. The project also included
2923-526: The Austin Natural Science Center moved into the eastern portion of the bathhouse and significant alterations to the building were made. The patio on the southeastern side of the building was covered, and animal pens were installed along the outside of the eastern wall. Educational programs were hosted there, and exhibits on native Texas wildlife were on display. The western side of the bathhouse, however, remained dedicated to pool activities. After
3002-441: The Deep Eddy Bathing Beach was "as much carnival ground as swimming pool". A Ferris wheel was built, as well as a 70-foot slide that emptied into the pool. There were "springboards, a flying trapeze, flying rings, horizontal bars and a forty-foot diving tower." Free silent movies were shown on a movie screen that was installed in the park adjacent to the pool, and a variety of entertainers performed such as Fred Lowery , Marcia Burke
3081-529: The Natural Science Center moved to Zilker Park in the 1980s, the building was used as office space until it was discovered that structural problems with the roof made it unsafe to occupy. Consequently, that portion of the bathhouse became a "forgotten city asset" until an effort to restore the bathhouse was spearheaded by the Friends of Deep Eddy group in 2002. In 2003, for safety reasons, the city removed

The Zilker Hillside Theater hosts regular performances by local theatre companies, including free "Shakespeare in
3555-454: The early and mid-1980s by designers and landscape architects with environmental concerns. They have recently been growing in popularity as an alternative to traditional swimming pools. Natural pools are constructed bodies of water in which no chemicals or devices that disinfect or sterilize water are used, and all the cleaning of the pool is achieved purely with the motion of the water through biological filters and plants rooted hydroponically in
3634-561: The first patrons of arts. Ancient Sinhalese built a pair of pools called " Kuttam Pokuna " in the kingdom of Anuradhapura , Sri Lanka, in the 6th century AD. They were decorated with flights of steps, punkalas or pots of abundance, and scroll design. Swimming pools became popular in Britain in the mid-19th century. As early as 1837, six indoor pools with diving boards existed in London, England. The Maidstone Swimming Club in Maidstone , Kent

In 1939, Oxford created its first major public indoor pool at Temple Cowley. The modern Olympic Games started in 1896 and included swimming races, after which the popularity of swimming pools began to spread. In the US, the Racquet Club of Philadelphia clubhouse (1907) boasts one of

A variation was the later development of sea- or harbour-side pools that circulated sea water using pumps. A pool of this type was the training ground for Australian Olympian Dawn Fraser . There are currently about 100 ocean baths in New South Wales , which can range from small pools roughly 25 metres long and "Olympic Sized" (50m) to
4345-607: The pool. Depth must be at least 2 m (6.6 ft). The water must be kept at 25–28 °C (77–82 °F) and the lighting level at greater than 1500 lux . There are also regulations for color of lane rope, positioning of backstroke flags (5 metres from each wall), and so on. Pools claimed to be "Olympic pools" do not always meet these regulations, as FINA cannot police use of the term. Touchpads are mounted on both walls for long course meets and each end for short course. A pool may be referred to as fast or slow, depending on its physical layout. Some design considerations allow

In essence, natural pools seek to recreate swimming holes and swimmable lakes, the environment where people feel safe swimming in a non-polluted, healthy, and ecologically balanced body of water. Water in natural pools has many desirable characteristics. For example, red eyes, dried-out skin and hair, and bleached swimsuits associated with overly chlorinated water are naturally absent in natural pools. Natural pools, by requiring
