Whether to build a dam

Positive Impacts

-There will be less floods

Lesser crops would be lost

-Able to control floods

Lesser crops would be affected by the floods

-There will be more water available

Crops would grow better

-Farmers downstream will be saved

Negative Impacts

-Farms will be put underwater and destroyed due to the flood that will cover the land

-Those who live behind the dam will have to leave their homes as the land would be flooded

People might not get used to staying in other place resulting in a not comfortable stay

-Spend money to buy expensive fertilizers to replace slit to grow crops as slit will be trapped below the newly dam

Farmers might have little profit and might not be able to purchase fertilizers

-Soil is no longer fertile

It is almost impossible to grow crops.

-When there are no avaliable farms, there would not be any food avaliable.

Opinion on proposal

I do not think it is a good idea as the farms are the best agricutural land that they have,and they have learnt to adapt to the floods and learnt to counter the floods too. They feel that the government should not disrupt the flooding as there might be terrible consquences like what happened in Egypt after building the Aswan dam.

Positive Effects

Increase of water supply to Brisbane to reduce the impact of lack of water.

Water for agri-culture

Use for recreational activity like Swimming pool,canoeing etc...

water for cooling of machinery,washing buildings ,washing of machinery etc...

Prevention of loss human life as there is no more flooding,to ensure public safety.

Less money used for repairing of flood damage and money can be used for other uses.

Less buildings will be damaged due to absence of flooding.

Generation of electricity via Hydroelectric plant.

Can be used as a new way to produce electricity.

Negative effects

Large amount of money used for building and maintaining the dam.

Farmers will complain as lack of fertile land below the dam.

fishermen who depend on the fish for their livelyhood will be affected and will affect the local fishing industries too.

Opinion on proposal

I think it is a good idea as we can save alot of money on repairs and we can prevent the loss of human life,which is our top priority as the government.We can also decrese our carbon credits as we can produce greener energy.

Positive effects

Rise in river temperature

It causes species of fishes that are unable to survive in cold river to thirve in the now warm river.

Negative Effects

Due to reduced water speed, silt will collect behind the dam,making the land below the dam less fertile.

The reservior will not be able to collect as much water as silt collects, making it shallower.

Many species of animals will be affected example: fish might not be able to travel up stream to spawn,so thier population will decrease.

Rubbish will collect behind the dam and the dam's slow moving water will stop the rivers natural cleaning mechcanisms.

Opinion on proposal

It is not recommended to build a dam as ot causes a lot of harm to the ecosystem, forcing a lot of fishes to extinction. It also leads to pollution of the river as, the waste materials deposited into the river are unable to exit as it will be blocked by the dam.

Positive Impacts

The flooding will stop and
so, buildings and structures
will stop being damaged.Hence,
place will become safer. Familes
then could have a better life
and dont have to be so worried
about safety.

Negative Impacts

If the dam breaks, flooding
will continue. So, it means
the dam is a temporary
way to stop flooding.So,
must find another better way.

Opinion on proposal

Its a good idea. Many
people in the company
lost homes and even
love ones. Hope that
the dam will end the
flood forever.Think that
its also good for attracting
tourist when reservoir
is created and when
there are new recreational
activities there.
