Canals are man made water ways used in different ways in Holland, or more accurately, Netherlands. They were dug around a lake, a dyke was build in between and the water out of the lake was pumped into the canal. The reclaimed land from the lake is then known as a "polder". The canals are usually linked up with other waterways and canals and pump houses can the regulate the water levels. Canals are also used for irrigation for the reclaimed land and a way of transport, as the produce could easily be transported with a "praam" (flat boat). They are also great for ice skating in winter and as most canals are connected with other water ways, you can easily cover 20 to 200-km on your skates. Hope that answered your question.
