Moraine-dammed lake

From Wikipedia, the free encyclopedia

A moraine-dammed lake occurs when a terminal moraine has prevented some meltwater from leaving the valley. Its most common shape is that of a long ribbon (ribbon lake). Example of moraine dammed lakes include:

• New Zealand: Lake Hawea, Lake Ohau, Lake Pukaki, Lake Tekapo, Lake Wakatipu, and Lake Wanaka (i.e., almost all large lakes in the South Island)
• Switzerland: Lake Zurich
• United States: Donner Lake in California, Flathead Lake in Montana, Mille Lacs Lake in Minnesota, Wallowa Lake in Oregon
• Wales: Llyn Peris and its twin Llyn Padarn.
