A colossal structure of earth and rock stands before us. This is Leslie Harrison Dam. It’s more than just a dam; it’s a silent guardian of Brisbane’s water supply.
Leslie Harrison Dam impounds the Tingalpa Creek. It provides roughly 20% of Redland City’s water. Imagine the countless homes and businesses reliant on this reservoir. The dam was completed in 1968. It was named after Robert Leslie Harrison a Queensland parliamentarian. He sadly passed away in 1966.
The dam’s impressive size is breathtaking. It’s 25 meters high and stretches 535 meters long. The dam wall holds back an enormous volume of water. At full capacity the reservoir contains a staggering 13206 megalitres of water. That’s enough water to fill millions of bathtubs. The catchment area for this impressive reservoir is 87 square kilometers. That’s a vast area including parts of the Venman Bushland National Park.
The dam’s history isn’t just about construction. In 1984 it underwent a significant upgrade. Controlled gates were added. These increased the water supply to the region. However these gates were removed in 2014 to enhance dam safety. This highlights the ongoing commitment to both water security and public safety.
Today Leslie Harrison Dam remains a vital part of South East Queensland’s water infrastructure. It’s a testament to engineering prowess. It’s also a reminder of the constant need to balance water management and environmental considerations. There are no plans for recreational activities at the dam. Seqwater prioritized water quality for the Redlands. They conducted comprehensive studies to assess the impact of recreation. The dam’s primary function remains securing the precious resource of drinking water.
As we stand here gazing at Leslie Harrison Dam let’s appreciate its significance. It silently works to support the lives of many. It is a vital part of Brisbane’s infrastructure.
