The dam supplies about 80 percent of the potable water for the entire city of Accra and its surrounding environs.
[1][2][3] Its construction began in 1974 and was completed in 1978 by Messrs Tahi, an Italian Company.

Victims claimed that the flooding was as a result of the Bortianor Traditional Council refusal to dredge the river that flowed into the sea until the Homowo festival had ended.
