The ideas about the Holocene fluctuations of the Lake Nero level differ among researchers. We have studied the structure of bottom sediments and bottom topography in the deepest northeastern part of the lake. A bathymetric survey was carried out. Drilling with the selection of undisturbed columns, GPR profiling, radiocarbon dating and a set of lithological analyzes were performed. Stratigraphic unconformities in the structure of bottom sediments indicate a drop in the lake level during the Lateglacial and the early Holocene. The level dropped to 87 m asl, which is 7 m lower than the current water level in the lake. The size of the lake at this stage was reduced several times. From 9 to 6.5 ka BP a transgressive stage was established: the average level of the lake could have risen to 91–94 m asl, which is close to its modern level. From 6.5 to 2.4 ka BP a decrease in the level by 1–3 m below the current one is revealed, followed by a gradual increase in the level. The current level was reached 300–500 years ago. The main factor in the fluctuations in the level of Lake Nero in the Holocene is the change in the height of the runoff threshold, caused by the transformation of the Ustye, Veksa, and Kotorosl river sistems. This transformation was associated both with regional changes in fluvial activity and with the processes of self-development of river channels.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324897568">Палеогидрологическая обстановка в Ростовской низине (Ярославская область) является предметом многолетних дискуссий. Представления о голоценовых колебаниях уровня озера Неро существенно расходятся у разных авторов. Нами исследовано строение донных отложений и рельефа дна в наиболее глубокой северо-восточной части акватории озера. Проведена батиметрическая съемка. Выполнены бурение с отбором ненарушенных колонок, георадарное профилирование, радиоуглеродное датирование и комплекс литологических анализов. Стратиграфические несогласия в строении донных отложений указывают на падение уровня озера в позднеледниковье и раннем голоцене. Глубина падения достигала отметки 87 м абс., что на 7 м ниже современного уровня воды в озере. Размеры озера на этом этапе сокращались в несколько раз. С 9.0 до 6.5 тыс. л. н. установлен трансгрессивный этап: средний многолетний уровень озера мог подниматься до 91–94 м абс., что близко к современным показателям. В интервале от 6.5 до 2.4 тыс. л. н. фиксируется снижение уровня на 1–3 м ниже современного. Затем начинается постепенный рост уровня вплоть до достижения современных значений 300–500 л. н. Основной фактор колебания уровня озера Неро в голоцене – изменение высоты порога стока, вызванное вертикальными деформациями речных русел Устья, Которосли и Вексы. Эти деформации были связаны как с региональными изменениями флювиальной активности, так и с процессами саморазвития русловых систем.</p></trans-abstract><kwd-group xml:lang="en"><kwd>paleolimnology</kwd><kwd>lacustrine deposits</kwd><kwd>ground-penetrating radar</kwd><kwd>facies analysis</kwd><kwd>hiatuses</kwd><kwd>Rostov lowland</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>палеолимнология</kwd><kwd>георадиолокация</kwd><kwd>озерные отложения</kwd><kwd>фациальный анализ</kwd><kwd>перерывы в осадконакоплении</kwd><kwd>флювиальные процессы</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Laboratory and analytical studies and reconstruction of the Nero fluctuations were carried out at the expense of the Megagrant (agreement No. 075-15-2021-599 dated 06/08/2021).
