Why do lakes not flood?

Most lakes experience fluctuating water levels, but they usually don't "flood" the way rivers do because lakes typically have outlet streams or rivers to help them drain. But not all lakes have such outlets, and these "closed-basin lakes" are prone to potentially catastrophic floods if their water level rises too high.

Accordingly, why does flood occur?

A flood occurs when water inundates land that's normally dry, which can happen in a multitude of ways. Excessive rain, a ruptured dam or levee, rapid melting of snow or ice, or even an unfortunately placed beaver dam can overwhelm a river, spreading over the adjacent land, called a floodplain.

Subsequently, question is, who is responsible for flood prevention? Water companies are Risk Management Authorities (RMAs) and play a major role in managing flood and coastal erosion risks. They manage the risk of flooding to water supply and sewerage facilities and flood risks from the failure of their infrastructure.

Then, why are the Great Lakes flooding?

At a Glance. Water levels on the Great Lakes remain at near-record high values as of early December. Coastal erosion and lakeshore flooding concerns are increased this winter due to the higher water levels. Excessive precipitation caused the Great Lakes to experience record-high water levels this year.

Can the Great Lakes Flood?

This US heartland has been flooded for five months. About 800 miles to the east, floods hit Buffalo, New York, on Lake Erie in two of the last three years, while Lake Michigan's historically high waters inundated parts of Chicago throughout the spring and summer months.
