Question: What river flows through the city where Ali Harter was born?

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: 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 3: Oklahoma: In Sand Springs, an outdoor amphitheater called "Discoveryland!" is the official performance headquarters for the musical Oklahoma! Ridge Bond, native of McAlester, Oklahoma, starred in the Broadway and International touring productions of Oklahoma!, playing the role of "Curly McClain" in more than 2,600 performances. In 1953 he was featured along with the Oklahoma! cast on a CBS Omnibus television broadcast. Bond was instrumental in the title song becoming the Oklahoma state song and is also featured on the U.S. postage stamp commemorating the musical's 50th anniversary. Historically, the state has produced musical styles such as The Tulsa Sound and western swing, which was popularized at Cain's Ballroom in Tulsa. The building, known as the "Carnegie Hall of Western Swing", served as the performance headquarters of Bob Wills and the Texas Playboys during the 1930s. Stillwater is known as the epicenter of Red Dirt music, the best-known proponent of which is the late Bob Childers.
Document 4: 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 8: 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.

Only a small section of the original lake remains, located outside the Federal District, in the municipality of Atenco, State of Mexico.
