In the Article possibilities of use of GIS-technologies for an assessment of a geoecological condition of water and lake objects are considered. The algorithm of creation of digital models of a relief of reservoirs with use of methods of geoinformation technologies is developed for definition of a geoecological condition of water objects. Use of data on a relief of a bottom will allow to carry out monitoring of erosive processes and will form a basis for complex researches of water ecosystems. The developed algorithm of creation of digital model of a relief of a bottom of water objects is based on use of materials of the field researches executed with use of geoinformation equipment and technologies. Initial materials for carrying out research are received with use of the GARMIN GPSMAP62 GPS navigator, GARMIN Fishfinder140 sonic depth finder, RADEKS40 radiometer and rn-meter. The special attention was paid to water and lake objects. As a result of computer processing of the received materials the digital model of an underwater relief of reservoirs which can form a basis for monitoring of erosive processes, an evtrofikation and the analysis of habitats of rare species of plants is created. On materials of field researches and the analysis of data of remote sensing of Earth the attributive tables of the specialized thematic GIS «Lakes of the Ivanovo Region» including more than 20 parameters are filled. It provides display of lakes of the Ivanovo region in different scales, layer-by-layer submission of information (96 thematic layers), display of attributes, search in inquiry, calculation the kartometricheskikh of characteristics.
