Beaverhill Lake ((クリー語:amisk-wa-chi-sakhahigan)) is a large lake in central Alberta, Canada. It is a site of regional importance in the Western Hemisphere Shorebird Reserve Network. It is managed by the Canadian Wildlife Service division of Environment Canada. It is located 70 km southeast of Edmonton, near the town of Tofield, and lies in the hydrographic basin of North Saskatchewan River. As recently as 1990, the lake had a total area of 139 km² and a maximum depth of only 2.3 m.〔 Like similar "prairie pothole" lakes, Beaverhill lake has receded significantly in recent years, losing about one quarter of its depth between 1999 and 2009. 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.〔Alberta Community Development - (Beavehill Natural Area ), (Beaverhill Lake Heritage Rangeland Natural Area )〕 The Beaverhill Lake Group, a stratigraphical unit of the Western Canadian Sedimentary Basin was named for this lake. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Beaverhill Lake」の詳細全文を読む スポンサード リンク
