Dauphin Lake
From Wikipedia, the free encyclopedia
Dauphin Lake was named by the heir to the French throne in 1739, Francois de la Verendrye. It is in western Manitoba near the city of Dauphin, Manitoba. The lake covers an area of 200 square miles and has a drainage basin of about 3250 square miles. The Mossy River drains the lake into Lake Winnipegosis. The basin is drained by seven major streams and has a total relief of 1900 feet.
In 1964, a new dam was constructed at Terin's Landing at the outlet of the lake. The Mossy River dam is still in use today. It is a ten bay concrete stoplog structure complete with a fish ladder.
Regulation of the lake is diffcult. Conditions can change very quickly. For example a four day rain in June of 1947 produced an estimated peak inflow of 60,000 cubic feet per second. At normal levels, the Mossy river can only take out about 500 cubic feet per second.
The lake provides wonderful recreational opportunities. Fishing is popular in both winter and summer, many people camp on the lake's shores and there are many cottages.
