Question: Kern Island Canal and Indiana Harbor and Ship Canal are both what? 
Context: The Grand Calumet River is a 13.0 mi river that flows primarily into Lake Michigan.  Originating in Miller Beach in Gary, it flows through the cities of Gary, East Chicago and Hammond, as well as Calumet City and Burnham on the Illinois side.  The majority of the river's flow drains into Lake Michigan via the Indiana Harbor and Ship Canal, sending about 1500 cuft per second of water into the lake.  A smaller part of the flow, at the river's western end, enters the Calumet River and ultimately drains into the Illinois and ultimately the Mississippi River. Carrier Canal is an irrigation canal in Kern County, California.  It originates from a common diversion at Manor Street in Bakersfield, which also supplies the Kern Island Canal and Eastside Canal.  The common diversion originates from the Kern River about 1 mi south of Gordon's Ferry.  There are additional diversions from the Kern River at Golden State Highway (SR 204 freeway) and Coffee Road.  The canal terminates at the Kern River, near Enos Lane west of Bakersfield.  For its entire length, it runs roughly parallel to the Kern River. Mill Creek is a district in Downtown Bakersfield, California.  It is primarily a mixture of residential and commercial on the east side of downtown.  Since the mid-2000s, the district has gone through major redevelopment.  These included, the development of the Kern Island Canal into a walking path (also called Mill Creek), the redevelopment of Central Park, construction of the Federal Courthouse, and construction of several new housing and commercial developments. The Chicago, Indiana and Southern Railroad (reporting mark CI&S) is a defunct railroad which operated in the states of Illinois and Indiana during the early 20th century.  The CI&S formed in 1906 from the consolidation of the two other railroads: the Indiana, Illinois and Iowa Railroad and the Indiana Harbor Railroad.  The new railroad also owned the capital stock of the Danville and Indiana Harbor Railroad.  The stock of the new company itself was wholly owned by the Lake Shore and Michigan Southern Railway and the Michigan Central Railroad, both of which were part of the New York Central system.  A 1907 report called the CI&S a "tributary to the Lake Shore."  The railroad operated two lines: a north-south line between Indiana Harbor (East Chicago, Indiana) and Danville, Illinois, and a line from the Spring Valley coalfields at Seatonville, Illinois, to South Bend, Indiana.  Together the two lines controlled 301 mi of track.  In 1914 the CI&S was one of several railroads consolidated to form the modern New York Central Railroad. Kern Island Canal is an irrigation canal in Kern County, California.  It primarily irrigates farmland located on the Kern Lakebed, south of Bakersfield.  It originates from a common diversion at Manor Street in Bakersfield, which also supplies the Carrier Canal and Eastside Canal.  The common diversion originates from the Kern River about 1 mi south of Gordon's Ferry. The Whiting Refinery is an oil refinery located on the southwestern shore of Lake Michigan and the Indiana Harbor Ship Canal and operated by BP.  The facility is primarily located in Whiting, Indiana, USA, though portions of the 1400 acre complex span into the neighboring cities of Hammond and East Chicago. Eastside Canal is an irrigation canal in Kern County, California.  It originates from a common diversion at Manor Street in Bakersfield, which also serves the Carrier Canal and Kern Island Canal.  The common diversion originates from the Kern River, about 1 mi south of Gordon's Ferry.  The canal terminates south of Bear Mountain Boulevard (SR 223), just west of Arvin. The Indiana Harbor and Ship Canal is an artificial waterway on the southwest shore of Lake Michigan, in East Chicago, Indiana which connects the Grand Calumet River to Lake Michigan.  It consists of two branch canals, the 1.25 mile (2 km) Lake George Branch and the 2 mile (3 km) long Grand Calumet River Branch which join to form the main Indiana Harbor Canal.  The Indiana Harbor Canal also functions as a harbor and runs 1.4 miles (2 km) before reaching the Indiana Harbor which connects to Lake Michigan.  In 2002, Indiana Harbor was the 45th busiest harbor in the United States, handling almost 13,300,000 short tons (12,000,000 metric tons) of cargo.  Foreign trade accounted for only 500,000 short tons (450,000 metric tons) of that.  Indiana Harbor is not a state-managed harbor, and it is maintained by the Chicago District of the U.S. Army Corps of Engineers, as authorized by the Rivers and Harbors Act of 1913. I-Pass (stylized as I-PASS) is the electronic toll collection system utilized by the Illinois State Toll Highway Authority (ISTHA) on its toll highways that launched on November 18, 1993, with the opening of Interstate 355 (Veterans Memorial Tollway).  It uses the same transponder as the E-ZPass system used in the Northeastern US and the Indiana Toll Road, along with the future Indiana State Road 912 (Cline Avenue) Indiana Harbor and Ship Canal bridge. The Indiana Harbor East Breakwater Light is an active aid to navigation that marks the end of a breakwater on the east side of the Indiana Harbor and Ship Canal where it enters Lake Michigan.
