Question: Which is older, the North Shore Channel, or the Friant-Kern Canal?
Context: The North Shore consists of many affluent suburbs north of Chicago, Illinois, bordering the shores of Lake Michigan.  These communities fall within suburban Cook County and Lake County.  The North Shore's membership is often a topic of debate, and is sometimes expanded to include other affluent Chicago suburbs which do not border Lake Michigan.  However, Evanston, Wilmette, Kenilworth, Winnetka, Glencoe, Highland Park, Lake Forest, and Lake Bluff are generally considered to be the core members of the North Shore, as all are affluent communities that border the lake just north of Chicago.  Other suburbs such as Glenview, Northbrook, Deerfield, Highwood, Skokie, and Northfield are often considered to be a part of the North Shore, but do not border Lake Michigan. The Evanston Wilmette Community Golf Course, formerly known as the Peter N. Jans Memorial Golf Course and locally called the Canal Shores Golf Course, is an 18-hole, par 60 golf course located in a suburban residential neighborhood on the east side of Evanston and Wilmette, Illinois.  Founded in 1919 on the banks of the North Shore Channel of the Chicago River, the course is 3,904 yards in length, featuring a narrow and tree-lined fairway and two over-the-water holes.  Eleven of the holes are located in Evanston, Illinois and 7 holes are in Wilmette, Illinois. The Edward R. Ladd Arboretum is an arboretum located at 2024 McCormick Boulevard, Evanston, Illinois, occupying 23 acres (93,000 m²) in a narrow three-quarter mile (1.2 km) stretch between McCormick Boulevard and the North Shore Channel on land leased from the Metropolitan Water Reclamation District of Greater Chicago. West Ridge is one of 77 Chicago community areas.  It is a middle-class neighborhood located on the far North Side of the City of Chicago.  It is located in the 50th Ward and the 40th Ward.  Also historically called North Town, and frequently referred to as West Rogers Park, it is bordered on the north by Howard Street, on the east by Ridge Boulevard, Western Avenue, and Ravenswood Avenue, the south by Bryn Mawr Avenue and Peterson Avenue, and on the west by Kedzie Avenue and the North Shore channel of the Chicago River.  At one time joined with neighboring Rogers Park, it seceded to become its own village in 1890 over a conflict concerning park districts (known as the Cabbage War).  West Ridge was annexed to Chicago on April 4, 1893, along with Rogers Park. The Lower North Shore refers to the Sydney Harbour Peninsula that is located on the north side of the Sydney Harbour Bridge.  The three bodies of water that surround the Lower North Shore are Lane Cove River on its western boarder, Sydney harbour on its south side, and Middle Harbour on its east.  The Lower North Shore borders the Upper North Shore when the Lane Cover River and Middle Harbour are at their closest. North Park is one of 77 well-defined community areas of the City of Chicago.  It is bordered by the North Shore Channel on the east, the Chicago River's North Branch and Foster Avenue on the south, Cicero Avenue on the west (except for the section in the northwest corner, north of Bryn Mawr Avenue, which is part of the Sauganash neighborhood) and Devon Avenue on the north. The North Shore Line is a railway line serving the North Shore in Sydney, New South Wales, Australia.  The North Shore Line extends from Sydney Central station through the western limb of the City Circle, across the Sydney Harbour Bridge and through the North Shore area to Hornsby where it joins the Main North Line.  Most services on the line are part of the T1 North Shore, Northern & Western Line, with some services to Wyong during peak hours. The Delta–Mendota Canal is a 117 mi aqueduct in central California, United States.  It is part of the Central Valley Project and its purpose is to replace water in the San Joaquin River that is diverted into Madera Canal and Friant-Kern Canal at Friant Dam.  Average annual throughput is 1993000 acre feet . The North Shore Channel is a drainage canal built between 1907 and 1910 to flush the sewage-filled North Branch of the Chicago River down the Chicago Sanitary and Ship Canal.  The sewage carrying duty has been largely taken over by the Chicago Deep Tunnel, but there are still occasional discharges due to heavy rains. The Friant-Kern Canal is a 152 mi Central Valley Project aqueduct managed by the United States Bureau of Reclamation in Central California to convey water to augment irrigation capacity in Fresno, Tulare, and Kern counties.  Construction began in 1949 and the canal was completed in 1951, at a cost of $60.8 million.
