The report is devoted to further analysis of satellite observations of the area of the hill collapse that occurred in December 2018 on the banks of the Bureya River opposite the place where the Sredny Sandar River flows into it. In 2019, in the area of the canal formed in the embankment on the Bureya River, two significant events occurred that caused particular concern of specialists: spring ice drift and the second in volume summer rain flood, after the catastrophic flood of 2013. Observations showed that the alarming forecasts of the repeated collapse of the coast and blocking the Bureya river canal were not confirmed. Floodwaters contributed to the erosion of the embankment and a slight expansion of the canal. Also, satellite monitoring made it possible to identify and analyze seasonal changes in the hydrological regime of the Sredny Sandar River, which appeared in connection with the changed landscape. As a result of the analysis, it was found that the period of complete cleansing of the Sredny Sandar River from the ice increased by almost a month compared to the average long-term value, and the period of ice formation decreased by 12 days. Now the situation in the collapse area is stable, there is no threat of flooding of the settlements of Chekunda, Elga and Ust-Urgal, the emergency mode removed. The inflow of water into the reservoir returned to normal, the Bureyskaya HPP is operating normally. In the future, the natural erosion of the embankment by the flow of water and the restoration of the Bureya river bed will continue, but this process will take a long time.
