Do dams retain water?

How many Litres of water are in a reservoir?
The Reservoir Holds 3.5 gallons / 13.2 litres of solution. The frequency of fill rate and nutrient replacement will depend on multiple factors such as plant size and quantity, ambient temperature and watering frequency.
Are they releasing water from Warragamba Dam?
Warragamba Dam spillway is currently releasing water at a rate of 450 gigalitres per day (GL/day) and that rate could increase as inflows to the dam storage continue to rise. (By comparison Sydney harbour is estimated to hold 500 GL).
Which dam holds the most water?
Kariba Dam Kariba Dam is the worlds biggest dam based on water storage capacity. Located at the former Kariwa (Kariba) Gorge, the dam creates Lake Kariba, which has a storage capacity of 185 billion cubic metres of water and a surface area of 5,580km2.
How long do dams last?
The average lifespan of a dam is often estimated to be 50 years. (6) Another water policy expert (7) estimates that, on average, between 0.5% and 1% of a reservoir is filled by sediment each year, meaning that most dams would have a lifespan of 100-200 years.
