Diatomaceous water-plants – unicellular, shallow microscopic organisms, the forms of cages are round mostly, sticks, three-cornered, to theoval trapezoid, cylindrical. In a cage outside of protoplasm there is a thintransparent shell, he outside consists of two durable armor silica. A sizeof cage is 4-2000 microns. In this work it was studied the intensificationof phytoplankton growth in a special environment, developed for growing diatoms. Diatomaceous water-plants meet in many places. A basicenvironment of their habitation is water. In water wide spread type ofbenthos and plankton. Some one-celled and colonial diatomaceous waterplants stick to and sprout on water water-plants and plants. Diatomaceouswater-plants have a 5600 kinds. The article provides the results of researchand alga taxonomic definition of species of diatoms in Lake Balkhash andBukhtarma reservoir. 2015 October of Lake Balkhash and Bukhtarma reservoir water sample was taken as the research object. Diatomaceous cageswere counted. As a result of research work, in Balkhash, were identifiedfollowing diatoms: Nitzchia, Pinnularia viridis, Gomphonema truncatum,Navicula sp., Fragillaria, Synedra ulna, Сyclotella commensis, Cymbella.In Bukhtarma lake Pinnularia viridis, Fragillaria crotenensis, Navicula sp.,Nitzchia palea, Synedra ulna, Сyclotella, Asterionella. In order to improvethe environmental situation of Kapchagay reservoir fill is recommended tostop, clean and waste water in a steel mill to control the amount of waterthat irrigates.Key words: lake Balkhash, Bukhtarma reservoir, diatoms, Centrophyceae.
