Hillsborough was a three-decker cargo ship launched in 1783. She completed six voyages to India and China as an East Indiaman for the British East India Company (EIC) between 1784 and 1798. In 1798, she was sold to new owners and repurposed to transport convicts from England to New South Wales. After disembarking her convicts in 1799, she was employed as a whaler in the South Seas fisheries until her dismantling in 1804.

History

The Itō-Ōkawa River is a primary source of drinking water for the city of Itō, on the eastern coast of the Izu Peninsula. However, the area is a region of heavy rains, and is prone to typhoons. The 1958 Kanogawa Typhoon caused widespread flooding and damage to property in the Itō area. From the 1960s, the area around Itō began to develop as a bedroom community for Atami, as well as a popular vacation destination due to its beaches, hot spring resorts and ease of access to Tokyo. In 1972, a project office was established and construction begun by a consortium consisting of Kajima Construction and Kumagai Gumi. Due to the geography of the site, a rock-fill dam design with a central spillway and a height of 63 meters was selected. The estimated completion time was 1983. However, due to difficulties arising from transporting the necessary stones from distant locations, work was not completed until 1989. Although styled as a 'multi-purpose dam', the dam has no associated hydroelectric power facilities, and its primary function is flood control and the supply of drinking water.

The reservoir impounded was named Lake Matsukawa (松川湖, Matsukawa-ko) in 1987, and is a popular recreational area for sports fishermen and bird-watching.
