I know lots just keen to learn info on things I didn't know I'm mainly asking this because in Maze there was water drops on the roof anyone know what that's about?
Look at the weather (e.g. at
http://www.bom.gov.au/vic/forecasts/melbourne.shtml) and make a judgement call. Safest is 0% chance of rain, 0 mm.
Don't expect this to be 100% accurate. Weather, particularly in Melbourne, is notoriously unpredictable. If the sky is overcast or grey, consider your moves carefully. I rarely go draining unless it's thoroughly sunny.
Some drains contain a connection to a cooling tower or other runoff (sometimes illegally installed) from a nearby factory or other building. These sometimes dump their water into the drain, causing a temporary 'flood'. Other water sources, such as firefighting equipment, burst water mains and people washing cars, can also do this. However, you shouldn't assume this is the always the case and when you do see a rise in water levels, leave as safely and quickly as you can.
Not sure what you mean by 'water drops'. If you mean droplets of water on the ceiling, that might be water evaporating from the base flow (i.e. the water constantly flowing through the drain) and condensing on the ceiling, which might be colder in some parts depending on how the drain changes in height. If it's a constant drip, it may be water leaking from an old mains or just the base flow from a tributary to the drain (i.e. a sidepipe).
