It was converted from a sand quarry that was used by the Housing and Development Board (HDB). Construction of the reservoir began in 1983, with the construction of a deep pumping station and a perimeter road. The reservoir was completed in June 1985, and it began operations later that year. Reservoir Bedok Reservoir is now open to water sports activities such as wakeboarding, sailing, Forest Adventure fishing, canoeing and kayaking. This follows the Singapore Sports Council's (SSC's) efforts to allow water sport enthusiasts to make use of the various reservoirs for activities which do not compromise the quality of the water. The programme kicked off with the HSBC Wakeboard World Cup Singapore 2004, held at Bedok Reservoir on 30–31 October 2004 and this was the first international water sports event to be held at a local reservoir. The hill on the west part of Bedok Reservoir is a popular place to fly model gliders. Bedok Reservoir Park The Bedok Reservoir Park was developed around the reservoir.
