Brisbane gets its water from all over the place. There are multiple dams linked into the water grid, and engineers can control the flow from each one. If we go back to drought conditions, we can summon up desalinated water or recycled water to add into the mix.
Brisbane's (in fact Queensland's) first major dam is the Enoggera Dam, about ten kilometres from the CBD in the suburb of The Gap. This dam was commenced in 1864 and finished in 1866, and was built to replace the previous water supply that emanated from Wheat Creek in the city. Here is a photograph of the Enoggera Dam from around 1888.

The dam's engineer, Joseph Brady, designed a very efficient dam that had three outlet pipes to draw water, rather than the usual single or dual pipe systems. This photograph is from 1912.

Being relatively close to the city, it has long been a favourite spot for a walk or a picnic. These folks were heading for a picnic at the reservoir back in 1900.

But the ensuing drought saw the infrastructure being brought back into service, and I dare say that it might be operating for a few years yet. Here is a recent picture.
