Oak Hammock Marsh
Oak Hammock Marsh consists of approximately of open marsh, and a slightly smaller area of surrounding woods and grasslands. The total Wildlife Management Area is 36 sq km. It is located approximately 20 km directly north of Winnipeg, Manitoba, Canada, near the town of Stonewall, Manitoba in the Rural Municipality of Rockwood.
Oak Hammock Marsh is listed as a Wetland of International Importance under the Ramsar Convention, and is also a globally significant Important Bird Area.
==History==
The marsh is a remnant of an originally 470 sq km area of marsh and fen near the south-western corner of Lake Winnipeg. This larger marsh had the original English name of St. Andrews Bog. But the original wetland underwent drainage for agricultural purposes beginning in 1897, and by the early 1960s all but 60 ha had been drained. Measures to restore a portion of the wetland began in 1967 when the Governments of Manitoba and Canada embarked on a cooperative program with Ducks Unlimited Canada and other wildlife conservation organizations to restore marginal agricultural lands to a state suitable for wildlife.
By 1974, 3,450 ha of land had been purchased and 22 km of dykes built to trap and hold water in three dyke-separated marsh compartments. In addition, 58 nesting islands were constructed within the three compartments. In 1984, the Manitoba government signed a further development agreement with Ducks Unlimited Canada to construct water control structures, water supply works, more nesting islands, additional dykes, and create a fourth compartment.
