The water nerd part...
A few lasts comment on history... During World War II the Biesbosch was used by the Dutch to escape from the Germans. The vast network of narrow canals and soggy, difficult-to-access land made it the perfect hiding spot. Also, 5 beavers were successfully reintroduced to the Biesbosch in 1988 (apparently the last native beaver was clubbed to death in 1825). Today there are over 60 beaver dams in the Biesbosch.
