Question: What river flows through the city where Donda West's funeral was held?

full_context: Document 1: 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 2: Kanye West: In September 2013, West was widely rebuked by human rights groups for performing in Kazakhstan at the wedding of authoritarian President Nursultan Nazarbayev's grandson. He traveled to Kazakhstan, which has one of the poorest human rights records in the world, as a personal guest of Nazarbayev. Other notable Western performers, including Sting, have previously cancelled performances in the country over human rights concerns. West was reportedly paid US$3 million for his performance. West had previously participated in cultural boycotts, joining Shakira and Rage Against The Machine in refusing to perform in Arizona after the 2010 implementation of stop and search laws directed against potential illegal aliens.
Document 3: Kanye West: On November 10, 2007, at approximately 7:35 pm, paramedics responding to an emergency call transported West's mother, Donda West, to the nearby Centinela Freeman Hospital in Marina del Rey, California. She was unresponsive in the emergency room, and after resuscitation attempts, doctors pronounced her dead at approximately 8:30 pm, at age 58. The Los Angeles County coroner's office said in January 2008 that West had died of heart disease while suffering "multiple post-operative factors" after plastic surgery. She had undergone liposuction and breast reduction. Beverly Hills plastic surgeon Andre Aboolian had refused to do the surgery because West had a health condition that placed her at risk for a heart attack. Aboolian referred her to an internist to investigate her cardiac issue. She never met with the doctor recommended by Aboolian and had the procedures performed by a third doctor, Jan Adams.
Document 4: 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 5: Kanye West: In 2008, following the death of West's mother, the foundation was rechristened "The Dr. Donda West Foundation."  The foundation ceased operations in 2011.
Document 6: 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 7: Kanye West: Adams sent condolences to Donda West's family but declined to publicly discuss the procedure, citing confidentiality. West’s family, through celebrity attorney Ed McPherson, filed complaints with the Medical Board against Adams and Aboolian for violating patient confidentiality following her death. Adams had previously been under scrutiny by the medical board. He appeared on Larry King Live on November 20, 2007, but left before speaking. Two days later, he appeared again, with his attorney, stating he was there to "defend himself". He said that the recently released autopsy results "spoke for themselves". The final coroner's report January 10, 2008, concluded that Donda West died of "coronary artery disease and multiple post-operative factors due to or as a consequence of liposuction and mammoplasty".
Document 8: 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 9: Kanye West: The funeral and burial for Donda West was held in Oklahoma City on November 20, 2007. West played his first concert following the funeral at The O2 in London on November 22. He dedicated a performance of "Hey Mama", as well as a cover of Journey's "Don't Stop Believin'", to his mother, and did so on all other dates of his Glow in the Dark tour.
Document 10: 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 11: Kanye West: West's life took a different direction when his mother, Donda West, died of complications from cosmetic surgery involving abdominoplasty and breast reduction in November 2007. Months later, West and fiancée Alexis Phifer ended their engagement and their long-term intermittent relationship, which had begun in 2002. The events profoundly affected West, who set off for his 2008 Glow in the Dark Tour shortly thereafter. Purportedly because his emotions could not be conveyed through rapping, West decided to sing using the voice audio processor Auto-Tune, which would become a central part of his next effort. West had previously experimented with the technology on his debut album The College Dropout for the background vocals of "Jesus Walks" and "Never Let Me Down." Recorded mostly in Honolulu, Hawaii in three weeks, West announced his fourth album, 808s & Heartbreak, at the 2008 MTV Video Music Awards, where he performed its lead single, "Love Lockdown". Music audiences were taken aback by the uncharacteristic production style and the presence of Auto-Tune, which typified the pre-release response to the record.
Document 12: 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 13: Kanye West: Kanye Omari West was born on June 8, 1977 in Atlanta, Georgia. His parents divorced when he was three and he and his mother moved to Chicago, Illinois. His father, Ray West, is a former Black Panther and was one of the first black photojournalists at The Atlanta Journal-Constitution. Ray West was later a Christian counselor, and in 2006, opened the Good Water Store and Café in Lexington Park, Maryland with startup capital from his son. West's mother, Dr. Donda C. (Williams) West, was a professor of English at Clark Atlanta University, and the Chair of the English Department at Chicago State University before retiring to serve as his manager. West was raised in a middle-class background, attending Polaris High School in suburban Oak Lawn, Illinois after living in Chicago.
Document 14: 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 15: Westminster Abbey: On Saturday September 6, 1997 the formal, though not "state" Funeral of Diana, Princess of Wales, was held. It was a royal ceremonial funeral including royal pageantry and Anglican funeral liturgy. A Second Public service was held on Sunday at the demand of the people. The burial occurred privately later the same day. Diana's former husband, sons, mother, siblings, a close friend, and a clergyman were present. Diana's body was clothed in a black long-sleeved dress designed by Catherine Walker, which she had chosen some weeks before. A set of rosary beads was placed in her hands, a gift she had received from Mother Teresa. Her grave is on the grounds of her family estate, Althorp, on a private island.[citation needed]
