Standing here, on the shores of Tingalpa Reservoir, do you ever wonder about the water you drink? The water that quenches your thirst and nourishes your life comes from this very place. It’s a hidden treasure, a vital artery for the city, but few realize the story behind it.
Tingalpa Reservoir, also known as Leslie Harrison Dam, is a giant reservoir that supplies drinking water to the Redland City in Brisbane. Built in 1967 and upgraded in 1984, it’s designed to hold 13,200 million litres of water when it’s full. However, this wasn’t always a water source. Before the dam was built, Tingalpa Creek flowed freely. The creek’s catchment area covers 87 square kilometers. It was a wild and rugged place, but over time, with development in the area and the growing need for water, this area was transformed into the reservoir you see today.
One of the interesting facts is that the dam is un-gated, which means that when the reservoir reaches full capacity, the water flows over the spillway safely out of the dam. This might seem like a simple detail, but it’s a testament to the clever design of the dam. The spillway itself is a sight to behold. It’s a massive concrete structure, a testament to the ingenuity of the engineers who built it.
It’s a source of life that quietly serves millions without fanfare, a constant reminder of the delicate balance between nature and human ingenuity in the heart of the city. It’s a story of resourcefulness, adaptation, and the ever-present need to manage and protect our precious water resources.
