Lake Tekapo, New Zealand. A moraine-dammed lake, occurs when the terminal moraine has prevented some meltwater from leaving the valley. When a glacier retreats, there is a space left over between the retreating glacier and the piece that stayed intact which holds leftover debris . Meltwater from both glaciers seep into this space creating a ...
Tarn—a proglacial lake impounded by the terminal moraine of the retreating Schoolroom Glacier in Grand Teton National Park, Wyoming In geology, a proglacial lake is a lake formed either by the damming action of a moraine during the retreat of a melting glacier , a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic ...
Moraine-dammed lake – Type of lake formed by glaciation; Terminal moraine – Type of moraine that forms at the terminal of a glacier; Rogen moraine – Landform of ridges deposited by a glacier or ice sheet transverse to ice flow; Kame; Moraine examples.

Moraine-dammed lakes occur when glacial debris dam a stream (or snow runoff). Jackson Lake and Jenny Lake in Grand Teton National Park are examples of moraine-dammed lakes, though Jackson Lake is enhanced by a man-made dam. Kettle lake: Depression, formed by a block of ice separated from the main glacier, in which the lake forms
The area which will see the greatest increase in lake formation is the Southern Tibetan Plateau region from debris covered glaciers. [3] This increase in glacial lake formation also indicates an increase in occurrence of glacial lake outburst flood events caused by damming and subsequent breaking of moraine and ice.
A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glacier or a moraine is released. A water body that is dammed by the front of a glacier is called a marginal lake, and a water body that is capped by the glacier is called a sub-glacial lake. When a marginal lake bursts, it may also be called a marginal ...
The lake is fed by the Gurudongmar glacier and is a moraine-dammed lake. [3] It is located to the north of the Kanchendzonga range, in a high plateau area connected with the Tibetan Plateau. It provides one of the source streams, which joins the Tso Lhamo Lake and then form the source of the Teesta River. The lake remains completely frozen in ...
Moraine deposits left behind by glaciers can also dam rivers to form lakes, such as at Flathead Lake, also in Montana (see Moraine-dammed lake). Natural disasters such as earthquakes and landslides frequently create landslide dams in mountainous regions with unstable local geology.
