During the 1730s, the lake filled to its current size and shape.

So heavy were the rains that the lake filled in only three days.

Down its center, a long, narrow lake filled most of the floor.

So when the lake fills, residents to the south know it is just a matter of time.

A small lake now fills the place where the clay was removed.

During the last ice age, about 12,000 years ago, the lake filled the entire basin, 338 square miles, and was in places 900 feet deep.

In 1963 the whole area was flooded and a lake filled the valley.

The lakes eventually fill up with water returning to their previous state.

Since 1885 the lake has filled in 1886/1887, 1889/1890, 1916/1917, 1950, 1955 and 1974-1976.

The lake filled in 1897 and again in April 1989.
