Question: What river flows through the city where The Flaming Lips were formed?

full_context: Document 1: Oklahoma City: The city is roughly bisected by the North Canadian River (recently renamed the Oklahoma River inside city limits). The North Canadian once had sufficient flow to flood every year, wreaking destruction on surrounding areas, including the central business district and the original Oklahoma City Zoo. In the 1940s, a dam was built on the river to manage the flood control and reduced its level. In the 1990s, as part of the citywide revitalization project known as MAPS, the city built a series of low-water dams, returning water to the portion of the river flowing near downtown. The city has three large lakes: Lake Hefner and Lake Overholser, in the northwestern quarter of the city; and the largest, Lake Stanley Draper, in the sparsely populated far southeast portion of the city.
Document 2: Oklahoma City: Oklahoma City has a major park in each quadrant of the city, going back to the first parks masterplan. Will Rogers Park, Lincoln Park, Trosper Park, and Woodson Park were once connected by the Grand Boulevard loop, some sections of which no longer exist. Martin Park Nature Center is a natural habitat in far northwest Oklahoma City. Will Rogers Park is home to the Lycan Conservatory, the Rose Garden, and Butterfly Garden, all built in the WPA era. Oklahoma City is home to the American Banjo Museum, which houses a large collection of highly decorated banjos from the early 20th century and exhibits on the history of the banjo and its place in American history. Concerts and lectures are also held there.
Document 3: Oklahoma City: In 1993, the city passed a massive redevelopment package known as the Metropolitan Area Projects (MAPS), intended to rebuild the city's core with civic projects to establish more activities and life to downtown. The city added a new baseball park; central library; renovations to the civic center, convention center and fairgrounds; and a water canal in the Bricktown entertainment district. Water taxis transport passengers within the district, adding color and activity along the canal. MAPS has become one of the most successful public-private partnerships undertaken in the U.S., exceeding $3 billion in private investment as of 2010. As a result of MAPS, the population living in downtown housing has exponentially increased, together with demand for additional residential and retail amenities, such as grocery, services, and shops.
Document 4: REO Speedwagon: They made a list of songs to learn over the summer break, and Doughty landed a summer job to buy his first keyboard. On his Farfisa organ, he learned ``Light My Fire ''by The Doors. The members returned to school in the fall of 1967, and had their first rehearsal before classes even started. They named the band REO Speedwagon, from the REO Speed Wagon, a flatbed truck Doughty had studied in transportation history, and the initials are those of its founder Ransom E. Olds. Rather than pronouncing REO as a single word as the motor company did, they chose to spell out the name with the individual letters each pronounced (`` R-E-O''). An ad in the school newspaper produced their first job, a fraternity party that turned into a food fight. They continued to perform cover songs in campus bars, fraternity parties, and university events. The first lineup consisted of Doughty on keyboards, Gratzer on drums and vocals, Joe Matt on guitar and vocals, Mike Blair on bass and vocals.
Document 5: Ralph Molina: Born in Puerto Rico, Molina has been a member of Crazy Horse since they were formed in 1962 as Danny & the Memories. He has remained throughout the band's many personnel changes, and has performed on all releases by the band, with and without Young. Molina's style of drumming is characterized by simple, but steady beats and fills.
Document 6: Oklahoma City: Walking trails line Lake Hefner and Lake Overholser in the northwest part of the city and downtown at the canal and the Oklahoma River. The majority of the east shore area is taken up by parks and trails, including a new leashless dog park and the postwar-era Stars and Stripes Park. Lake Stanley Draper is the city's largest and most remote lake.
Document 7: John Mayer: Mayer considered skipping college to pursue his music, but his parents dissuaded him.  He enrolled in the Berklee College of Music in 1997 at age 19. At the urging of his college friend Clay Cook, they left Berklee after two semesters and moved to Atlanta. There, they formed a two-man band called LoFi Masters, and began performing in local coffee houses and club venues such as Eddie's Attic. According to Cook, they experienced musical differences due to Mayer's desire to move more towards pop music. The two parted ways and Mayer embarked on a solo career.With the help of local producer and engineer Glenn Matullo, Mayer recorded the independent EP Inside Wants Out. The EP includes eight songs with Mayer on lead vocals and guitars. For the opening track, "Back To You", a full band was enlisted, including the EP's co-producer David "DeLa" LaBruyere on bass guitars. Cook had co-written many of the album's songs, including its first commercial single release, "No Such Thing", However, his only performance contribution was backing vocals on the song "Comfortable".
Document 8: Dammam: Having been built from the ground up, the Dammam Area was designed from the outset on the principles of modern urban planning. Residential areas are separate from commercial sections, roads are broad and straight and buildings conform to a master plan. One of the main features of the development of the area is land reclamation. Vast stretches of the shallow Persian Gulf waters have been filled, with hotels and office buildings occupying what were once marshes. Water for household, urban and industrial use is provided by desalination plants that supply approximately seven million cubic feet of treated water to the area each day. The availability of water underpins the urban and industrial growth of the Dammam Area, and provisions have been made for expanding existing desalination facilities to meet future growth.
Document 9: Mexico City: Originally much of the valley laid beneath the waters of Lake Texcoco, a system of interconnected salt and freshwater lakes. The Aztecs built dikes to separate the fresh water used to raise crops in chinampas and to prevent recurrent floods. These dikes were destroyed during the siege of Tenochtitlan, and during colonial times the Spanish regularly drained the lake to prevent floods. Only a small section of the original lake remains, located outside the Federal District, in the municipality of Atenco, State of Mexico.
Document 10: Fall Out Boy: The band's first public performance came in a cafeteria at DePaul University alongside Stilwell and another group that performed Black Sabbath in its entirety. The band's only performance with guitarist John Flamandan and original drummer Ben Rose was in retrospect described as ``goofy ''and`` bad,'' but Trohman made an active effort to make the band work, picking up members for practice. Wentz and Stump argued over band names; the former favored verbose, tongue - in - cheek names while the latter desired to reference Tom Waits in name. After creating a short list of names that included ``Fall Out Boy, ''a fictional character from The Simpsons and Bongo Comics, friends voted on the name. The band's second performance, at a southern Illinois university with The Killing Tree, began with Wentz introducing the band under a name Stump recalled as`` very long.'' According to Stump, an audience member yelled out, ``Fuck that, no, you're Fall Out Boy!, ''and the band were credited later in the show under that name by Killing Tree frontman Tim McIlrath. As the group looked up to McIlrath, and Trohman and Stump were`` die - hard'' Simpsons fans, the name stuck. The group's first cassette tape demo was recorded in Rose's basement, but the band later set off for Wisconsin to record a proper demo with 7 Angels 7 Plagues drummer Jared Logan, whom Wentz knew through connections in the hardcore scene.
Document 11: Bee Gees: When it, too, failed to attract much interest, Mardin encouraged them to work within the soul music style. The brothers attempted to assemble a live stage band that could replicate their studio sound. Lead guitarist Alan Kendall had come on board in 1971 but did not have much to do until Mr. Natural. For that album, they added drummer Dennis Bryon, and they later added ex-Strawbs keyboard player Blue Weaver, completing the Bee Gees band that lasted through the late '70s. Maurice, who had previously performed on piano, guitar, harpsichord, electric piano, organ, mellotron and bass guitar, as well as mandolin and Moog synthesiser, by then confined himself to bass onstage.
Document 12: Palermo: Today both the Papireto river and the Kemonia are covered up by buildings. However, the shape of the former watercourses can still be recognised today, because the streets that were built on them follow their shapes. Today the only waterway not drained yet is the Oreto river that divides the downtown of the city from the western uptown and the industrial districts. In the basins there were, though, many seasonal torrents that helped formed swampy plains, reclaimed during history; a good example of which can be found in the borough of Mondello.
Document 13: Lake Texcoco: Tenochtitlan was founded on an islet in the western part of the lake in the year 1325. Around it, the Aztecs created a large artificial island using a system similar to the creation of chinampas. To overcome the problems of drinking water, the Aztecs built a system of dams to separate the salty waters of the lake from the rain water of the effluents. It also permitted them to control the level of the lake. The city also had an inner system of channels that helped to control the water.
Document 14: Michael Moore (bassist): Moore started on bass at age fifteen, at Withrow High School in Cincinnati, where he performed in ensembles and the Presentation Orchestra in George G. "Smittie" Smith's Withrow Minstrels. He played with his father in nightclubs in Cincinnati. He attended the Cincinnati College Conservatory, playing with Cal Collins and Woody Evans locally. He toured Africa and Europe with Woody Herman in 1966, and recorded with Dusko Goykovich while in Belgrade.
Document 15: Michael Ivins: Along with Mark Coyne and Wayne Coyne, he formed The Flaming Lips in 1983 in Oklahoma City, Oklahoma. According to frontman Coyne, Ivins was found as the bassist for the band because of his punk-rock look, and not because of his musical ability. In fact, Ivins initially couldn't play bass, but he learned how and has been the bassist for the band ever since. Ivins developed an interest in the recording process and has helped engineer the Flaming Lips' studio recordings since 1994.
