The Hardy River ((スペイン語:Río Hardy)) is a -long Mexican river formed by residual agricultural waters from the Mexicali Valley and running into the Colorado River. The river is believed to have been an ancient channel of the Colorado. In the 19th century, a sea captain (Captain Hardy) explored the Colorado River Delta, and noted that the main channel of the Colorado followed this course. Later in the 1880s, sea captains noted that the main channel of the Colorado had moved east, and this old channel became known as Hardy's Colorado. In much earlier times, the Colorado River periodically flowed north into the Salton Sink, forming a large lake called Lake Cahuilla. Eventually, Lake Cahuilla would fill to about 30' above sea level, at which point the lake would overflow its banks near Cerro Prieto and flow south to the Gulf of California. During those times, the Rio Hardy would serve as the overflow channel for Lake Cahuilla. ==Wildlife== The Rio Hardy is home to a variety of wildlife, including the mosquitofish and the sailfin molly (). The Hardy's wetlands are a nesting ground for the Snowy Egrets (Egretta thula). The wetlands and bird habitat are part of a protected Mexican Biosphere Reserve called the ''Reserva de la Biosfera del Alto Golfo de California y Delta del Rio Colorado'', (). 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「Hardy River」の詳細全文を読む スポンサード リンク
