Salmon Migration and Dam Environmental Impact Quiz

Study Notes

Salmon Cannon Purpose

The salmon cannon is designed to transport salmon over obstacles like dams, facilitating their natural migration patterns.
It uses a system of pneumatic tubes to safely guide fish, helping maintain salmon populations and ecosystem balance.

Negative Impact of Dams on the Environment

Dams disrupt natural river ecosystems, affecting aquatic habitats and biodiversity.
They impede fish migration, leading to a decline in various fish populations, particularly salmon.
Water flow alteration can result in changes to sediment transport, affecting downstream habitats.

Hydroelectric Energy Production

Hydroelectric energy accounts for approximately 16% of the world’s electricity production.
It represents a significant renewable energy source, harnessing the power of flowing water to generate power.

Initial Benefits of Manmade Dams

Manmade dams originally provided water storage for agriculture and irrigation.
They helped with flood control, protecting communities and farmland from seasonal flooding.
Dams enabled the generation of hydroelectric power, contributing to economic development.

Perception of Dams During Creation

Initially, dams were regarded as engineering marvels, showcasing human ingenuity and control over nature.
They were lauded for their potential benefits, such as power generation and agricultural expansion, often celebrated as advancements in technology.
