� dams have inundated the spawning grounds of fish� dams have inhibited the seasonal migration of fish� dams have endangered some species of fish� dams may have inundated the potential for archaeological findings� reservoirs can foster diseases if not properly maintained� reservoir water can evaporate significantly� some researchers believe that reservoirs can cause earthquakes� the reservoir created by the dam may inundate land, crops, cities and villages� people may be displaced by the reservoir and have to find new homes� the reservoir may cause instability of the hillsides
2) Endagering to many wildlife species - while some species of wildlife thrive in a reservoir environment, most are affected in a negative way. Creative (...and expensive) solutions usually need to be engineered to minimize the effect on the wildlife
(Case Study) By Lewis Ian Latham from Knowsley Park CFL.
The 3 Gorges Dam is the largest of its kind in Asia and located on the Yangzte River. The power created from this dam supplies China one tenth of their requirements which is a great deal as it is more than 3x larger than the UK alone. The people protected from this dam have risen over the years to above 2 million civilians, the power is clean which helps ecosystems, wildlife and air purity (a big problem in China)
However.... Over 2 million civilians were therefore displaced and had to move many miles to relocate mainly travelling to Chongqing. Both land slides and Earthquakes have been triggered from this dam as the water fluctuates over 30m annually so the flow can be maintained to protect the rural area. The weight from the dam puts pressure on the ground below and continues on to trigger earthquakes throughout the local areas. Behind every dam ever created can be found a resevoir, the one located behind the 3 Gorges is VERY LONG and DEEP. Over 100 Heritage Sites were lost and 13 Cities, 140 towns, 1300 villages, 1500 factories and 100,000 acres of land were submerged by the resevoir....
