Plants and grease underwater in a reservoir soon rot, lessen the amount of nutrient in the water, and eventually leading to a reduction in fish stocks. Some scientists believe that the Brobdingnagian weight of the water female genital organ dams may trigger earthquakes. small dams cause less ecological damage but governments and investors are often attracted by large dam-building projects. The over enthusiasm and depravation in these projects, result in untoward placed and faded dams. The unsuccessful person of such dams has caused a morsel of floods leading to death of life and property.
