What Are Some Effects of Rising Lake Water Levels?


Quick Answer

The effects of rising lake water include increased droughts, local flooding and a significant loss of wetlands. The rise of lake water is a direct result of global climate change.

The change in global temperature has caused heavier rains,and has also restricted the amount of water that is evaporated and absorbed by the ground. This imbalance in the water cycle has caused many lakes, including the Great Lakes, to rise considerably, as much as 3/4 meter in some cases. The area that has been hit the hardest by this rise is the Great Lakes region in the United States. Ten thousand miles of coastline is at risk of flooding, as the water level increases more every year.

Fluctuation in lake water level has occurred, as the average yearly temperatures fluctuate. As the climate continues to change, the rise in lake water has become more steady. Much of the rise in the lake water in the Great Lakes is due to a polar vortex that has caused lower average temperatures in that region and has reduced evaporation levels, while rain and melting levels have increased due to the higher-than-average global temperatures. Lakes in Germany have already experienced an 80 percent loss in wetlands due to a similar process.
