Question: Which canal was completed first, Dundee Canal or Cascade Locks and Canal?
Context: The Dundee Canal was an industrial canal in Clifton and Passaic in Passaic County, New Jersey.  It was built between 1858 and 1861 and ran parallel to the Passaic River.  It supplied hydropower and water for manufacturing.  There was interest by some members of the business community to modify the canal to support navigational uses, but the canal was never used for that purpose. The Bridge of the Gods is a steel truss cantilever bridge that spans the Columbia River between Cascade Locks, Oregon, and Washington state near North Bonneville.  It is approximately 40 miles (64 kilometers) east of Portland, Oregon, and 4 miles (6.4 km) upriver from the Bonneville Dam.  It is a toll bridge operated by the Port of Cascade Locks. The Junction Canal was a canal in the states of New York and Pennsylvania in the United States.  The canal was also called the Arnot Canal, after the name of its principal stockholder, John Arnot of Elmira, New York.  The canal was built and operated by a private stock company.  The canal was partly open in 1854, but the entire length was not finished until 1858.  The completed canal was 18 mi long and had 11 locks.  Then intent was to lengthen the reach of the Chemung Canal deeper into Pennsylvania in order to connect to the canal systems there.  Competition with railroads led to diminished use of the canal.  In 1865 the canal was severely damaged by a flood.  In 1866, the stock company was authorized to change its name to the "Junction Canal and Railroad Company," and work commenced in constructing a railroad on its right of way.  The canal was last used in 1871, and was then abandoned. The Cascade Locks Work Center, in Mt. Hood National Forest near the town of Cascade Locks, was built by the Civilian Conservation Corps in 1936.  It was listed on the National Register of Historic Places in 1986 for its architecture.  The Rustic style structures were designed by the architects of the United States Forest Service.  The listing includes three contributing buildings on a 1.9 acre parcel.  Historical the Work Center has been used as single dwelling and a warehouse. Cascade Locks is a city in Hood River County, Oregon, United States.  The city took its name from a set of locks built to improve navigation past the Cascades Rapids of the Columbia River.  The U.S. federal government approved the plan for the locks in 1875, construction began in 1878, and the locks were completed on November 5, 1896.  The locks were subsequently submerged in 1938, replaced by Bonneville Lock and Dam, although the city lost no land from the expansion of Lake Bonneville behind the dam some 4 mi downstream of the city.  The city population was 1,144 at the 2010 census.  The 2007 estimate is 1,075 residents. Cascade Locks School is a public school in Cascade Locks, Oregon, United States.  Opened in 1949, the school included high school grades until 2009.  The school includes grades K through 5. The Cascade Locks and Canal was a navigation project on the Columbia River between the U.S. states of Oregon and Washington, completed in 1896.  It allowed the steamboats of the Columbia River to bypass the Cascades Rapids, and thereby opened a passage from the lower parts of the river as far as The Dalles.  The locks were submerged and rendered obsolete in 1938, when the Bonneville Dam was constructed, along with a new set of locks, a short ways downstream. In the first decade of the 2000s, the Confederated Tribes of Warm Springs (a group of Indian tribes in the U.S. state of Oregon) sought to build a casino in the Columbia River Gorge.  They ended their pursuit of the project in 2013.  They considered various sites, as early as 1999; the most extensive plan called for a 60 acre facility with 250 hotel rooms in Cascade Locks, Oregon.  The proposed site is within the Columbia River Gorge National Scenic Area, and adjacent to a federally designated wilderness area, but within the city limits of Cascade Locks.  (The Columbia River National Scenic Area specifically exempts economic development projects within city limits and supports such growth for cities on both sides of the Columbia River). Cascade Locks State Airport (IATA: CZK, ICAO: KCZK, FAA LID: CZK) is a public use airport located one nautical mile (2 km) northeast of the central business district of Cascade Locks, a city in Hood River County, Oregon, United States.  It is owned by the Oregon Department of Aviation. The Oregon Portage Railroad was the first railroad in the U.S. state of Oregon.  It originally ran for 4.5 mi , with an accompanying 7 mi of telegraph line, and was later extended to a length of 15 mi .  The railroad was located on the south bank of the Cascades canal of the Columbia River.  It ran from Tanner Creek (near where Bonneville Dam was later built) to the Cascade Locks, which were under construction in the later years of the railroad's operation.  Although the Oregon Portage was the first railroad in Oregon, it was not the first along the Columbia River.  Francis A. Chenoweth operated a rail line on the river's north bank in present-day Washington in 1851.
