The O’Brien County Conservation Board was formed in 1964 by the decision of the county’s voters. The purpose of the board, which is supported by Iowa law, is to acquire, develop, maintain and make available to the inhabitants of the county, public museums, parks, preserves, parkways, playgrounds, recreational centers, county forests, wildlife and other conservation areas, and to promote and preserve the health and general welfare of the people, to encourage the orderly development and conservation of natural resources, and to cultivate good citizenship by providing adequate programs of public recreation.
