“…The longest course of the Baikal levels was reconstructed by A. N. Afanasyev from 1747, in which century-old cycles and intra-century rhythms were determined [2]. A number of data on Baikal amplitudes has been extended until 2015 with the specification of the boundaries of "high-water and low-water years" for the historical and modern periods [7]. In this study, the boundaries of periods of high and low water content in the Selenga River basin are determined by the deviation of the average annual flow from the average long-term water flow (Fig.2).…”

The technogenic stage of relief formation of the river mouth systems of the Lake Baikal coast occurred during the rise of the basic level in the 50-70 years of the last century and continues to the present time. In the considered stage, there were at least 6 anomalies of river flow, which caused the onset of low-water and high-water periods in the Baikal basin. Changes in the basic conditions of formation of the Baikal coast were significantly reflected in the morphology of the largest river mouth system of the Selenga River, representing the protruding delta. The fluvial process is leading in delta-forming and is controlled by the level of the receiving reservoir, hydro-climatic events in the basin and seismotectonic manifestations in the coastal zone. During the mentioned period at the top of the Delta, there was a change of the type of channel process, the restructuring of the channel network, the formation of flood-plain terrace, channel meso – and microforms was noted. Morphometric analysis of cartographic data allowed building a hydrological and geomorphological model development of the relief of the Delta, as well as for the time sections corresponding to the periods of low water and high water.

“…In high‐pool periods, villages in Buryatia, which has a shallower shoreline, can experience flooding. But if extra water is discharged through the dam to lower lake levels, human settlements along the Angara can experience flooding as well (Nikitin, Abasov, Bychkov, & Osipchuk, 2019), as happened in the autumn of 2020 (TASS, 2020b). These problems are worsened by illegal and uncontrolled coastal development along Baikal and the Angara River in both regions (Yasakova, 2020).…”

Lake Baikal in eastern Siberia is the deepest and (by volume) largest lake on Earth. Among the most ancient lakes, it is home to thousands of endemic species. Lake Baikal is well‐known for its water purity, especially its dominant deep‐water layers, which consist of pristine, drinking‐quality water and is inhabited by unique endemics with enormous biodiversity. But some coastal sites of this giant lake (mainly localized in isolated shallow bays and littoral zones close to settlements and industrial sites) are suffering from an environmental crisis that threatens the water's quality and the ecosystem it supports. As part of the global ecosystem, Lake Baikal is already facing significant impacts from global climate change, which, in turn, increase the risks and consequences of local anthropogenic effects. Although the lake is protected by federal law, human activities are nevertheless having a growing negative impact on its ecosystem. Political, economic, and social factors result in cascading natural consequences in water quality, coastal sustainability, pollution sinks, water level management, forest maintenance, fire control and biodiversity. While Lake Baikal is a UNESCO World Heritage Site, known and valued around the world, it remains vulnerable to worsening threats that must be addressed if humanity is to preserve this unique ecosystem and its endemic species into the future.

“…In the last 20 years, the Lake Baikal has only been providing seasonal regulation. The 2014-2017 period of extremely low water demonstrated the insufficient validity and impossibility of implementing the Resolution under the water conditions other than normal one [9].…”

The paper discusses the trends, features, and current problems of the operation of hydro power plants in the interconnected power system (IPS) of Siberia. The main feature of the IPS of Siberia is a high proportion of hydro power plants and, as a result, a strong dependence of power generation on the natural fluctuations of water inflows into reservoirs. The problems affecting the power system efficiency arise when the inflows deviate from normal and close-to-normal values. The study indicates the need to improve the current system of managing and planning the operation of hydro power plants. The important factor that can increase the efficiency and reliability of the power system operation is bringing the permissible ranges of variations in reservoir levels in compliance with the design values. Planning the long-term power balances and increasing their validity should involve predictive scenarios of water inflows into reservoirs.
