The Chagres River in central Panama, is the largest river in the Panama Canal’s watershed. The river is dammed twice*, and the resulting reservoirs—Gatun Lake and Lake Alajuela—form an integral part of the canal and its water system. Although the river’s natural course runs northwest to its mouth at the Caribbean Sea, its waters also flow, via the canal’s locks, into the Gulf of Panama to the south.

Before the development of land infrastructure, boats and river transport played the role in transportation of goods. Bumboats did not only ply the well-known Singapore River and the quays. They also plied other water bodies like the Kallang River, Rochor River and Rochor Canal for transport purposes. Rochor Canal is a continuation of a canal that begins from as far as the Bukit Timah area, its water source. Officially, only the section after the Kandang Kerbau Bridge is named Rochor Canal. It continues along the aptly named Rochor Canal Road and ends at Victoria Bridge, where it continues as Rochor River. It is one of five waterways that empties into the Marina Reservoir.

Rochor Canal gave rise to one of the earliest industries in Little India – cattle trade. The natural pasture fed by the waters of the Rochor Canal suited cattle trade. Many streets in Little India are named after this cattle trade legacy, such as Belilios Road (named after a prominent cattle trader), Buffalo Road, Desker Road (named after an abbatoir merchant), and Kerbau Road (kerbau means cattle in Malay). Kandang Kerbau means buffalo or cattle pen in Malay. The growth of cattle trade fuelled other industries. The first municipal incinerators were constructed off Jalan Besar and later, more municipal abbatoirs were built. Along the canal were rubber factories, ice works, and markets for used goods.

Incline, Lake Biwa Canal, Kyoto, Japan


Keage Incline on Street View

Lake Biwa Canal is a waterway in Japan constructed during the Meiji Period to transport water, freight, and passengers from Lake Biwa to the nearby City of Kyoto. The canal supplied Japan’s first public hydroelectric power generator, which served from 1895 to provide electricity for Kyoto’s trams…Due to the 36 meter difference in elevation between the upstream dam and its terminus, an inclined plane was built, which allowed boats to travel on land via the use of a flat car on which they were placed. Operation of the 9 ft (2,743 mm) track gauge incline ceased in 1948.
