FIELD: ecosystem protection. ;SUBSTANCE: invention relates to the conservation of aquatic ecosystems of freshwater basins for the reproduction, development and maintenance of biological diversity, as well as providing the population with clean water and recreational fitness. A method for determining the level of the geoecological state of a freshwater reservoir consists in taking a water sample with a volume of at least 50 ml of water from water samples with the bathometer, taken at any depth and in any season of the year, placing it in a cuvette of a multichannel spectrophotometer and determining the spectral transparency at a light wave length of 430 nm, then using the Bouguer-Lambert-Beer formula, calculating the spectral index of light attenuation at a wavelength of 430 nm (m-1); the value of the optical index of the geoecological state of a freshwater reservoir is determined as the natural logarithm of the obtained value of the spectral attenuation index. The level of the geoecological state of a freshwater reservoir (m-1) is determined by the numerical value of the optical index of the geoecological state based on the gradation: 0-0. 34 - low level 1 (LL1), 0.35-0.69 - low level 2 (LL2), 0.70-0.91 - moderate level 1 (ML1), 0.92-1.09 - moderate level 2 (ML2), 1.10-2.3 - average level 1 (AL1), 2.31-3.1 - average level 2 (AL2), 3.11 and more - high level (HL). ;EFFECT: extension of the range of methods to control freshwater. ;1 cl, 4 tbl, 1 ex, 3 dwg
