River development projects in the form of multi-purpose dams were also drawn up for the Imagawa River water system, and in 1965 a dam in Aburagi, which is in the Tagawa District's Tsuno, entered into construction under the Imagawa Comprehensive Development Project. This became Aburagi Dam. Plans to build the dam were unveiled in 1961. The reasons for the selection of the specific location of the dam at a contracted point of the Imagawa River were that it was possible to secure an ample amount of active water storage capacity, and it was effective from a cost-performance perspective. However, after construction plans were unveiled, residents of the Tsuno area unanimously opposed the dam's creation. The reservoir area that would be created by the dam would be centered on Tsuno, and not only houses but town offices and public facilities would be submerged. Residents were fearful for their livelihoods, and requested large sums as compensation for relocation, complicating compensation negotiations. As the backer of the plan, Fukuoka Prefecture frequently entered into compensation negotiations, but talks continued at length for 3 years. In March 1968, 7 years after the plan to build the dam was initially unveiled, representatives of the residents reached an agreement on compensation negotiations, and construction was authorized to commence. However, the construction of the dam meant that 155 city-maintained residencies, as well as the Soeda town Hall, Tsuno Branch Office, elementary and junior high schools, post office, police substation, fire department branch office, community center, and agricultural cooperative branch office would all become submerged. Aburagi was thus sacrificed for the development of Kitakyūshū. Construction began, and areas where the ground quality was poor were reinforced with water-impermeable concrete walls, eventually leading to the dam's completion in 1971, 9 years after construction plans were announced. During dry periods, the former village of Tsuno—as well the bridge built across the Imagawa River and stone walls built around former residences—can still be seen sunken at the bottom of the dam. The submerged bridge across the Imagawa River actually became visible above the water during times of water shortage during 1994, and again in 2002 and 2007. Aburagi Dam is used for flood control, unspecified water utilization, and tap water provision, as well as industrial water provision and hydroelectricity generation, making the dam's purposes numerous even among multi-purpose dams. Based on these objectives, Aburagi Dam—along with Rikimaru Dam, Masubuchi Dam, the Tonda Reservoirs #1 and #2, Hata Dam, and Matsugae Dam—contributes to Kitakyūshū's water storage.
