It is located 70 km southeast of Edmonton, near the town of Tofield, and lies in the hydrographic basin of the North Saskatchewan River.[4]
As recently as 1990, the lake had a total area of 139 km2 (54 sq mi) and a maximum depth of only 2.3 m (7 ft 7 in)[4] Like similar "prairie pothole" lakes, Beaverhill lake receded significantly after much of its headwaters were diverted, in recent years it has lost about one-quarter of its depth between 1999 and 2009.[5]
The lake is an important bird habitat and has been designated as a "National Nature Viewpoint" by Nature Canada (formerly known as the Canadian Nature Federation) in 1981. The Beaverhill Natural Area was established in 1987 to protect the lake and its surrounding area. Beaverhill Lake Heritage Rangeland Natural Area is also established on what were the shores of the lake.[6]
The Beaverhill Lake Group, a stratigraphical unit of the Western Canadian Sedimentary Basin was named for this lake.

Озеро Биверхилл (англ. Beaverhill Lake ) — Бобровый холм — высохшее озеро в центральной части провинции Альберта (Канада). Расположено в 70 километрах юго-восточнее города Эдмонтона. Общая площадь — 139 км², глубина до 2,3 метров. Бассейн реки Норт-Саскачеван. Национальный парк Элк-Айленд[1] расположен примерно в 15 километрах на северо-запад от озера. Биверхилл — одно из важнейших мест для птиц на территории Альберты, так как озеро находится на маршруте миграции береговых и водоплавающих птиц на их пути в Арктику и обратно. Каждый год в мае и сентябре тысячи птиц становятся хозяевами на этом озере, большинство из них улетает дальше, но многие остаются на гнездование и проводят на озере всё лето.Другой контент может иметь иную лицензию.
