A survey of some watercourses in the southeastern part of the Kamchatka Peninsula was conducted. The Kamchatka, Andrianovka, Plotnikova, Avacha, Paratunka, Gavanka, Kirpichnaya, Karamshina, Mutnushka rivers and the Pervy Klyuch spring were studied. Water quality analysis using the Pantle-Buck method modified by SladeChek for the presence of algae species - indicators of organic pollution showed that at present the waters of nine surveyed watercourses are in good ecological condition, have a low degree of natural organic pollution. The quality of their waters is assessed as “practically clean” (class II) and “slightly polluted” (class III). The only exception is the Mutnushka River, whose waters are classified as moderately polluted. All of the above data were obtained for the first time for the watercourses of the Kamchatka Peninsula and can serve as a basis for their further monitoring.
