A 37 million year old lake?

I was taught in school that lakes tend to be temporary, since
erosion will tend to fill in a basin rather than clean it out.
According to Wikipedia, http://en.wikipedia.org/wiki/Lake_Wanapitei
the impact that created Lake Wanapitei occured 37 million years
ago. Now, it may not have been a lake that whole time, but
whatever depression the impact created has had 37 million years
to fill in. And it probably *was* a lake for much of that time,
any time it was below the local water table. Why is it still
concave?
