Question: California Aqueduct and Ohio and Erie Canal, are located in which country?
Context: Seneca River Crossing Canals Historic District is a national historic district located at Montezuma and Tyre in Cayuga and Seneca Counties, New York.  The district includes more than a mile of the Enlarged Erie Canal prism (built here between 1849 and 1857); towpath and heelpath; a drydock; the remains of the Richmond (Montezuma) Aqueduct crossing the Seneca River; remnants of the original Erie Canal, built between 1817 and 1825 and including Lock #62 and piers of the original mule bridge from that era; and a culvert that carries a stream beneath the Enlarged Erie Canal. Camillus Erie Canal Park is a town park in Camillus, New York that preserves a seven mile (11 km) stretch of the Erie Canal.  It includes the Nine Mile Creek Aqueduct, which is listed on the National Register of Historic Places.  The aqueduct underwent a $2 million restoration, completed in August 2009, which brought it back to navigable condition. Erie Canal: Second Genesee Aqueduct, also known as the Broad Street Aqueduct or Broad Street Bridge, is a historic stone aqueduct located at Rochester in Monroe County, New York.  It was constructed in 1836-1842 and originally carried the Erie Canal over the Genesee River.  The overall length of the aqueduct including the wings and abutments is 800 ft .  The aqueduct is 70 ft wide and has massive parapets on either side.  It is one of four major aqueducts in the mid-19th century Erie Canal system.  In 1927, a roadbed was added to carry automobile traffic and named Broad Street.  It also carried a part of the Rochester Subway. The Ohio and Erie Canal was a canal constructed during the 1820s and early 1830s in the U.S. state of Ohio.  It connected Akron, Summit County, with the Cuyahoga River near its outlet on Lake Erie in Cleveland, Cuyahoga County, and a few years later, with the River Ohio near Portsmouth, Scioto County, and then connections to other canal systems in Pennsylvania. Schoharie Crossing State Historic Site, also known as Erie Canal National Historic Landmark, is a historic district that includes the ruins of the Erie Canal aqueduct over Schoharie Creek, and a 3.5 mi long part of the Erie Canal, in the towns of Glen and Florida within Montgomery County, New York.  It was the first part of the old canal to be designated a National Historic Landmark, prior to the designation of the entire New York State Barge Canal as a NHL in 2017. Centreport Aqueduct is a historic aqueduct located in the town of Brutus near Weedsport in Cayuga County, New York.  The aqueduct was consrtructed in 1854-1857 as a part of the Weedsport section of the "Improved Erie Canal."  The wood and stone aqueduct carried the Erie Canal over Cold Spring Brook near its juncture with North Brook.  The aqueduct structure is approximately 125 feet in length, 125 feet in width, and 16 feet in height.  Improvements were made to the aqueduct in 1895 as part of the "Nine Million Dollar Improvement."  The aqueduct ceased being used after development of the New York State Barge Canal System in 1917.  The aqueduct stone work is still intact and is the prime feature of a roadside park constructed by the New York State Department of Transportation in 1972 with the assistance of the Weedsport Lions Club. The Harvey O. Banks Pumping Plant is located 2.5 miles (4 km) southwest of the Clifton Court Forebay and 12 miles (19 km) northwest of Tracy, CA.  The plant is the first pumping plant for the California Aqueduct and the South Bay Aqueduct.  It provides the necessary fluid head (potential energy) for the California Aqueduct to flow for approximately 80 miles (130 km) south past the O'Neill Forebay and the San Luis Reservoir to the Dos Amigos Pumping Plant.  The Banks Pumping Plant initially flows into the Bethany Reservoir.  It is from the Bethany Reservoir that the South Bay Aqueduct begins. Erie Canal Lock 52 Complex is a national historic district located at Port Byron and Mentz in Cayuga County, New York.  The district includes two contributing buildings (the Erie House and the blacksmith shop / mule barn); three contributing engineering structures (Erie Canal Lock 52, culvert, and canal prism of the enlarged Erie Canal); and archaeological sites associated with the canal operations.  Lock 52 was constructed 1849-1853 as part of the Enlarged Erie Canal program.  It remained in operation until the rerouting of the canal under the New York State Barge Canal System in 1917.  The Erie House was built in 1894 and is a two story frame structure that housed a saloon and hotel. 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. Tinkers Creek Aqueduct is an aqueduct that was constructed to bridge the Ohio and Erie Canal over Tinkers Creek near its confluence with the Cuyahoga River in Valley View, Ohio.  It is a relatively rare surviving example of an Ohio and Erie Canal aqueduct.  It was originally constructed in 1825-1827 by, and re-built due to flood damage in 1845 and 1905.  Tinkers Creek Aqueduct was included in a National Historic Landmark district established in 1966, and it was separately listed on the National Register of Historic Places in 1979.  The original Tinkers Creek Aqueduct was a wood plank, steel truss, and Ashlar-sandstone structure constructed in 1827, south of the present aqueduct's location.  Cuyahoga River and Tinkers Creek flooding caused continual damage to the original aqueduct, so successive structures were built in 1845 and 1905 in the present location.  Today, Tinkers Creek Aqueduct is the only aqueduct which remains of the four original aqueducts in the Cuyahoga Valley.  Of Furnace Run Aqueduct, Mill Creek Aqueduct, Peninsula Aqueduct, and (?  Yellow Creek ?)  Aqueduct; Mill Creek Aqueduct, of newer construction, is the only aqueduct which still carries Ohio and Erie Canal water.  After 102 years of flooding, weathering, and deterioration, Tinkers Creek Aqueduct was removed in 2007.  The National Park Service is currently working on Phase II of the project to reconstruct it from newer materials.
