On April 1st the temperature dropped a lot due to the el nino effect. The ocean temperature effects the weath er patterns and causes the temperature to drop. The temp. drops due to the water temperat1ures of the ocean. The pressure from the ocean currents pushes the hot or cold air across the U.S. The air can carry precipitation to the Great Lakes. The precipitation can cause the Great Lakes levels to rise.

GREAT LAKE LEVELS
The great lakes consist of Lake Huron, Lake Ontario, Lake Michigan, Lake Superior, and Lake Erie. There levels can rise and drop due to a varity of reasons. When several months of above-average precipitation occur with cooler, cloudy conditions that cause less evaporation, the levels gradually rise. Likewise, prolonged periods of lower-than-average precipitation and warmer temperatures typically result in lowering of water levels. So in order for the levels to be affected you need to have either several months of above average precipitation or several months o
f below average precipitation.
When the Great Lakes levels rise after months of above average rain expensive lake front property can be damaged. Waves can erode the land and leave it damaged. On the other hand when the levels drop resorts and marinas sometimes dont have enough water to launch their boats. When the water drops channels dry up and fish can not get throu
Because the major factors affecting the water supply to the lakes such as precipitation, evaporation and runoff the levels cannot be controlled or accurately predicted for more than a few weeks into the future.
