The Lal Lal Reservoir (built in 1970 [229] with a capacity of 59,500 megalitres (1.57 × 10 10 US gallons) [230]) is Ballarat's largest water catchment accounting for approximately two-thirds of the city's water usage. [231] The White Swan reservoir (built in 1952 [229] with a 14,100 Ml (3.7 × 10 9 US gal) capacity) supplies most of the ...
The flow of the creek is supplemented by a release of 2,000 megalitres (440,000,000 imp gal; 530,000,000 US gal) of treated waste water per year from the Ballarat North Treatment Plant. [4] The lake outlet is situated in the south-west shore of the lake and flows into Baillie Creek, which is a tributary of Hopkins River .
At this state, the reservoir is termed fully drawn down. For example, if built to supply water in the dry season, it is the water left behind when no more water can be extracted. Frequently, the effective minimum volume is greater if the water is needed for a purpose behind a dam. Available capacity May require knowing the reservoir's primary ...
In 1877 the Gong Gong reservoir was built to alleviate flooding and to replace Lake Wendouree as the primary water source for Ballarat. By the turn of the century, the river had become heavily polluted during the early industrialisation of Ballarat. During the 1960s, the river through the Ballarat CBD was re-routed, concreted and built over.
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Normally A increases with Q and S because the higher the water level is the higher the discharge capacity becomes. The factor is therefore called Aq instead of A. The non-linear reservoir has no usable unit hydrograph. During periods without rainfall or recharge, i.e. when R = 0, the runoff equation reduces to Q2 = Q1 exp { − Aq (T2 − T1 ...
The reservoir has a live capacity of 3,700,000 m 3 (3,000 acre⋅ft). From the balancing reservoir, water is again sent south through the 8.53 m dia, 12.38 km (8 mi) long Sundar Nagar Slapper tunnel.
