<P> Tenochtitlan was founded on an islet in the western part of the lake in the year 1325 . Around it , the Aztecs created a large artificial island using a system similar to the creation of chinampas .

It also permitted them to control the level of the lake . The city also had an inner system of channels that helped to control the water . </P>
