Abstract

A spectacular lake, situated behind a sliding wave, was very well preserved near the Căianu Mic village (Bistriţa-Năsăud County). GPS technique used in topo-bathymetric measurements were facilitate the obtaining of some important informations and leded to the unit lake and its area GIS modeling. Comparison of previous measurements, maked with great rigor by surveyor and limnology specialists of our faculty, with measurements made by the authors of this study, made it possible a sharp dynamic of the lake area and its basin. In this sense, horizontal and vertical mobility of the sliding wave is evident, and also a small lake basin silting. Our predecessors considered important a pisciculture capitalization of the lake, because their communist society followed the maximal output in all domains. But, we consider opportune a touring capitalization of the objective, considering the beauty and spectacular landscape components, regardless of the season. Simultaneously it is necessary a lake protection by its framing into geomorphologic protected sites category, given the fragile specific ecosystem developed there and the highly dangerous access on the steep and friability slopes of the lake.
