Lake Malawi is over 350 miles long, over 2,300 feet deep, ... Several thousand foot mountains drop down into the blue water and then continue down over 2,000 feet underwater.

Six years ago, Martin Hobbs had never swum a mile. This week, he cemented a world record by swimming 361 miles – the full length of Lake Malawi in Africa.

The National Water Resources Authority says Lake Malawi’s waters have risen to their highest level in more than a decade: 52 centimetres higher than last year.
