The Gippsland Lakes
Excersises..
a)Because it was open to the sea lakes entrance in the 1980s. This is flushing lots of sea water making the lake salty.

b) The lakes water temperature is increasing due to global warming so the temperature is rising.

c) This is because Australia is going through a drought and there is very little rainfull to fill up lake Victoria.

d) This is because vegetation has been removed there for Animals die creating a great environment for algal blooms. Due to ferteliser and temperature rise, also increases the number of algal blooms.

e) When trees get removed from the edge of creeks there are no roots to keep the soil in place so when it rains, the soil goes into the creeks and stops water from entering the lakes.
