The dive

How all of the lakes, also here it is necessary take caution to the order and not to approach too much to the backdrop in order to avoid to put in suspension the very fine sediment, typical of environments of low energy. The underwater environment is very fascinating for the special feelings that succeeds to transmit the underwater. Diving in the Lake of Posta Fibreno is very different from diving in other places. The lake’s outstanding visibility allows divers at depth to see people walking along the beaches of the lake and clouds running across the sky. From behind the filter of the clear, icy water of the lake at Posta Fibreno, the external world, the non-aquatic world, appears very different. However, once in the water, divers become a part of this vulnerable ecosystem, so it is important that they be very careful not to disturb it; excellent buoyancy control and a refined skill-set go a long way in minimizing human impact on this beautiful, but fragile, ecosystem. Observing the banks is very easy to bump into a nàue, a typical boat of the place, entirely in wood and from the deep one entirely dish. The nàue is realized with oak of wood of aces nailed and glued between them with a special mixture of musk and flour and capable of to transport a loaded with 7/8 quintals. Such boat seems is very like to that already in use I press the ancient peoples italici. A particularity is that after to have used it, the nàue, comes immersed in the lake so that the rays of the sun and the dampness do not distort it, and every anytime again should be used goes brace outside from the water and emptied entirely.

Despite their bad reputation, meeting a Coypus underwater is still a fantastic experience, especially if one is lucky enough to meet a brave individual or one accustomed to the presence of human beings. Being careful not to scare it, observing the graceful underwater movements of these animals is quite a treat. Viewing one of these animals swimming free, in the clean, clear, cold waters of the Lake of Posta Fibreno must surely be one of the most treasured memories a scuba diver can have.

An other peculiarity of the area is the presence, perhaps the only in Europe and cited in the past from Plinio in his work “Naturalis Historia”, of an island floating, the rota, formed over thousands of years through an accumulation of algae, grass, shrubs and trees, is not anchored to the bottom of the lake but is mobile, and moves in different directions depending on wind velocity. From 1983 the area was submitted to environmental protection, actual to want to protect the natural particularity that mark it; is an of the naturalistic oasis more interesting and incontaminate in Central Italy, rich of flora and of fauna lake
