Question: Which is longer, Central Arizona Project or Augusta Canal?

full_context: Document 1: California Aqueduct: The Governor Edmund G. Brown California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern and Central California to Southern California. Named after California Governor Edmund Gerald "Pat" Brown Sr., the over 400 mi aqueduct is the principal feature of the California State Water Project.
Document 2: Central Arizona Project: The Central Arizona Project (CAP) is a 336 mi (541 km) diversion canal in Arizona in the United States. The aqueduct diverts water from the Colorado River from the Bill Williams Wildlife Refuge south portion of Lake Havasu near Parker into central and southern Arizona. The CAP is the second largest and expansive aqueduct system ever constructed in the United States. CAP is managed and operated by the Central Arizona Water Conservation District (CAWCD). It was shepherded through Congress by Carl Hayden.
Document 3: Edison Sault Power Canal: The Edison Sault Power Canal supplies the Saint Marys Falls Hydropower Plant, a Cloverland Electric Cooperative hydroelectric plant, in Sault Ste. Marie, Michigan. Excavation of the power canal began in September 1898 and was completed in June 1902. The canal and hydroelectric complex were named a Historic Civil Engineering Landmark in 1983.
Document 4: Colorado River Aqueduct: The Colorado River Aqueduct, or CRA, is a 242 mi water conveyance in Southern California in the United States, operated by the Metropolitan Water District of Southern California (MWD). The aqueduct impounds water from the Colorado River at Lake Havasu on the California-Arizona border west across the Mojave and Colorado deserts to the east side of the Santa Ana Mountains. It is one of the primary sources of drinking water for Southern California.
Document 5: Power canal: A Power Canal refers to a canal used for hydraulic power generation, rather than for transport of watercraft. The power canal was a major factor in the Industrial revolution in New England in the 19th century. Most early power canals were mill races used mechanically to transfer power directly from falling water to machinery in mill buildings. Later, the hydraulic power generated electricity locally for the same mill factories. These power canals were often filled in as electricity (transported by power lines) replaced the need for local water power, and road transport needs or city expansion needs reclaimed the land. Some hydraulic power canals were transformed into local electric generators, but most were closed. Remains of power canals can be seen in old mill towns and are often protected as historical structures today.
Document 6: Augusta Canal: The Augusta Canal is a historic canal located in Augusta, Georgia, United States. The canal is fed by the Savannah River and passes through three levels (approximately 13 miles total) in suburban and urban Augusta before the water returns to the river at various locations. It was devised to harness the water power at the fall line of the Savannah River to drive mills, to provide transportation of goods, and to provide a municipal water supply. It is the only canal in the US in continuous use for its original purposes of providing power, transport and municipal water.
Document 7: Schuylkill Canal: Schuylkill Canal is the common, but technically inaccurate, name for the Schuylkill Navigation, a 19th-century commercial waterway in and along the Schuylkill River in the U.S. state of Pennsylvania. The "canal" was actually a system of interconnected canals and slack-water pools in the river, which is called a navigation. Chartered in 1815, the Schuylkill Navigation opened in 1825 to provide transportation and water power. At the time, the river was the least expensive and most efficient method of transporting bulk cargo, and the eastern seaboard cities of the U.S. were experiencing an energy crisis due to over forestation. It fostered the mining of anthracite coal as the major source of industry between Pottsville and eastern markets. Along the tow-paths, mules pulled barges of coal from Port Carbon through the water gaps to Pottsville; locally to the port and markets of Philadelphia; and some then by ship or through additional New Jersey waterways, to New York City markets.
Document 8: Folsom South Canal: The Folsom South Canal is an aqueduct in Northern California in the United States. The canal diverts water from the American River at Nimbus Dam in Sacramento County and travels about 26.7 mi in a southerly direction, terminating near Clay, about 10 mi northeast of Lodi. The canal is operated by the U.S. Bureau of Reclamation, as part of the Auburn-Folsom South Unit of the Central Valley Project. It is contracted for irrigation, industrial and municipal water supply; formerly it provided cooling water for the Rancho Seco Nuclear Generating Station. It is also connected to the Mokelumne Aqueduct, which provides a large portion of the San Francisco Bay Area's water supply.
Document 9: Columbia Basin Project: The Columbia Basin Project (or CBP) in Central Washington, United States, is the irrigation network that the Grand Coulee Dam makes possible. It is the largest water reclamation project in the United States, supplying irrigation water to over 670000 acre of the 1100000 acre large project area, all of which was originally intended to be supplied and is still classified as irrigable and open for the possible enlargement of the system. Water pumped from the Columbia River is carried over 331 mi of main canals, stored in a number of reservoirs, then fed into 1339 mi of lateral irrigation canals, and out into 3500 mi of drains and wasteways. The Grand Coulee Dam, powerplant, and various other parts of the CBP are operated by the Bureau of Reclamation. There are three irrigation districts (the Quincy-Columbia Basin Irrigation District, the East Columbia Basin Irrigation District, and the South Columbia Basin Irrigation District) in the project area, which operate additional local facilities.
Document 10: Brunswick–Altamaha canal: The Brunswick–Altamaha Canal was a 12-mile-long canal built to connect the Altamaha River to the city of Brunswick, Georgia at the Turtle River to transport goods from Brunswick's port to areas farther north and inland. It included locks on both ends of the canal. The canal was originally proposed in 1798 and after two failed charters (1826 and 1830), construction was started in 1836 by Thomas Butler King. The project was estimated to cost $450,000. The canal was finished and opened in 1854; however, by that time the canal was obsolete because of new railroads. The canal was closed by 1860. The Columbian mammoth was discovered during the construction of the canal.
Document 11: All-American Canal: The All-American Canal is an 80-mile (130 km) long aqueduct, located in southeastern California. It conveys water from the Colorado River into the Imperial Valley and to nine cities. It is the Imperial Valley's only water source, and replaced the Alamo Canal, which was located mostly in Mexico. The Imperial Dam, about 30 miles (48 km) northeast of Yuma, Arizona on the Colorado River, diverts water into the All-American Canal, which runs to just west of Calexico, California before its last branch heads mostly north into the Imperial Valley. Five smaller canals branching off the All American Canal move water into the Imperial Valley. These canal systems irrigate up to 630,000 acres (250,000 ha) of crop land and have made possible a greatly increased crop yield in this area, originally one of the driest on earth. It is the largest irrigation canal in the world, carrying a maximum of 26,155 cubic feet per second (740.6 m/s). Agricultural runoff from the All American Canal drains into the Salton Sea.
Document 12: New Waddell Dam: The New Waddell Dam is an embankment dam on the Agua Fria River in Maricopa County, Arizona, 35 mi northwest of Phoenix. It serves as part of the Central Arizona Project (CAP) while also providing water for the Maricopa Water District. The dam creates Lake Pleasant with water from the Agua Fria and also the CAP aqueduct. In addition, it affords flood protection, hydroelectric power production and recreational opportunities. Construction on the dam began in 1985 and ended in 1994. Its reservoir submerged the Old Waddell Dam which was completed in 1927 after decades of planning.
Document 13: Hayden-Rhodes Aqueduct: The Hayden-Rhodes Aqueduct is that section of the Central Arizona Project, an aqueduct system in Arizona, United States, formerly known as the Granite Reef Division.
Document 14: Augusta Subdivision: The Augusta Subdivision is a railroad line owned by CSX Transportation in the U.S. states of Georgia and South Carolina. The line runs from Augusta, Georgia to Yemassee, South Carolina for a total of 87.7 miles. At its north end it continues south from the McCormick Subdivision and at its south end it continues south as the Charleston Subdivision.
Document 15: Lowell Power Canal System and Pawtucket Gatehouse: The Lowell Power Canal System is the largest power canal system in the United States, at 5.6 miles in length. The system's estimated output is 10,000 horsepower, operating six major canals on two levels, controlled by numerous gates. The system was begun in the 1790s, beginning its life as a transportation canal called the Pawtucket Canal, which was constructed to get logs from New Hampshire down the Merrimack River to shipbuilding centers at Newburyport, Massachusetts, bypassing the 30-plus-foot drop of the Pawtucket Falls.
