Netley Libau Marsh preliminary engineering report. D. Flavell

TextPublication details: MB : 1982Online resources: Abstract: An engineering concept has been developed for the Netley-Libau Marshes which would provide the capability for water level control as recommended by Ducks Unlimited biologists. The primary factors presently limiting waterfowl and muskrat production which are addressed by the concept are short-term water level fluctuations in the marshes due to Lake Winnipeg wind tides, dropping water levels during the winter,flooding from the Red River, and lack of low water periods for rejuvenation of marsh vegetation. The works proposed to deal with these water control problems are a system of barriers (probably earth dykes)to protect the marshes from short-term water level fluctuations and from flooding from the Red River; pumps to drawdown the marshes; control structures which can be opened to provide a refill capability or closed to protect the marshes from water level changes; and separator dykes to divide the marshes into dependently operable units. Refer to Figure 2 for a map illustrating the
