Tammerkoski Rapid Between Lake Näsijärvi and Lake Pyhäjärvi is about 7500 Years Old
After the last ice age, post-glacial rebound has changed the topography of Finland enough to cause some lakes to develop new channels and to discharge into different directions than before. The rising surface level of Lake Näsijärvi to the north of Tampere eroded the sandy isthmus between Lake Näsijärvi and Lake Pyhäjärvi sufficiently to break a new channel into it about 7500 years ago. That channel is known as Tammerkoski today.
Here's a picture of Finland immediately after the last ice age:
A while ago I read that the finland land's is rising faster that sea levels due to the weight of the glaciers, if this is true it is a bit amazing but I really could not believe it.

Strange, are they sure about 7500 years.
I thought that the last ice age was yesterday.
People even wanted to take a selfie with me, because I looked like a snowman.

Yes, it was exactly 7500 years, 0 months, 1 day, 46 minutes ago. That's when ice age ended

That's a lot of water all over the map. Good thing it's a long time ago.
