As human populations have changed over the years, people have altered the course of rivers and other waterways to better suit th

eir needs. one approach has been through the damming of certain rivers. over time, many people question whether this effort has been beneficial. what are the negative impacts of damming a river that are being assessed?
dams allow more water to flow into nearby reservoirs, increasing the chances of disease transmission.
dams cause increases in salmon populations because more water is available for them to live in.
dams reduce salmon stocks, which reduces revenue and overall whale populations.
dams allow for invasive species to move around more easily, which reduces biodiversity.

Dams allowing more water to flow into nearby reservoirs thereby increasing the chances of disease transmission is its negative impact.

This is a form of barrier which restricts the flow of water for different reasons such as reservoirs, electricity generation etc.

Since the water flows to reservoirs in close proximity, it increases the risk of disease transmission such as malaria etc.
