HIGH ASWAN DAM

PROBLEM?

• Fishing industry has decreased
• Water isn't nutrient rich due to harmful salts and pesticides
• Farmers must use artificial fertilizers
• Contaminates get into water
• Parasites that cause schistosomiasis can infect the water

CAUSES

• Silt build up at bottom of Lake Nasser
• Natural nutrients also build up
• Waste products get into water supply
• Low nutrient water going into Mediterranean Sea

SOME BACKGROUND

• Government almost lost valuable artifacts from time of pharoahs
• Government almost lost valuable artifacts from time of pharoahs
• Land around Lake Nasser is more fertile from nutrients in the water
• Regulates water flow and gives irrigation systems water
• Caused a loss of wetlands-dam dried them up
• Silt builds up at the bottom of Lake Nasser instead of flowing through the water
• Silt builds up at the bottom of Lake Nasser instead of flowing through the water

LONG TERM EFFECTS

Untitled Slide

• Lake Nasser becomes smaller each year because of silt build up
• Build up also decreases amount of water going into dam

Untitled Slide

• Decreased power of the Nile downstream
• Water doesn't have natural nutrients

Untitled Slide

• Salt content will continue to rise

POSSIBLE SOLUTIONS

FIND ANOTHER SOURCE OF ELECTRICITY

CHANGE AGRICULTURAL PRACTICES

Untitled Slide

• Prevent salt and nutrients from building up

Untitled Slide

• Don't control the Nile River so strictly
