Abstract

A spectacular lake situated behind a sliding wave was preserved very well since the beginning of Holocene, near the village Caianu Small (Nasaud County). GPS technique used in making of rises topo-bathymetric and mobile kit with 12 physico-chemical measurements were used to facilitate obtaining important information that led to the modeling and GIS unit lake area, as well as the representation of quality parameters of water. Comparison of previous measurements, conducted with great rigor by specialist surveyors and Limnology of our faculty, with measurements made by the authors of this study made it possible to highlight a sharp dynamic area of the lake and its basin. In this sense, horizontal and vertical mobility of the sliding wave is evident, and a small lake basin clogging. Given the relatively small size of the lake, there are some differences of physico-chemical parameters, are related to the presence of underwater springs that feed the lake (temperature, dissolved oxygen) or local and zonal Petrography, with abundance and marly clay structures and the emergence of diapir structures (pH, electrical conductivity, salinity). Recommendations from our predecessors vis-a-vis the potential lake, made a kind of society which sought to obtain the maximum in any field, do you consider a tourism recovery target, given the beauty and spectacular landscape components regardless of season . Is necessary but a parallel objective to protect the geomorphological classification as category protected sites, given the fragile ecosystem developed specific and highly dangerous here related to access to steep slopes and friability of the lake.
