What institution entered into a cost-sharing contract with the Army Corps of Engineers in 1960?

The Florida Game and Fresh Water Fish Commission is the correct answer because, in 1960, this agency collaborated with the Army Corps of Engineers under a cost-sharing contract to manage and control aquatic vegetation in Florida waters. This partnership was essential in addressing issues such as invasive aquatic plants that affect water quality, fish habitats, and recreation.

This historic collaboration allowed for more effective and coordinated efforts in aquatic weed control, combining resources and expertise from both organizations. The arrangement emphasized the importance of state and federal teamwork in managing aquatic ecosystems, setting a precedent for future initiatives.

Other options do not represent the correct entity involved in the specific 1960 contract. The Florida Department of Environmental Protection primarily focuses on environmental protection and regulation, not specifically on fish and aquatic resources like the commission. The Florida Aquatic Weed Control Board, while related to aquatic maintenance, did not exist at that time in the same capacity or as a party to that particular contract. Lastly, the Florida Wildlife Federation, while dedicated to wildlife advocacy in the state, is not directly responsible for managing aquatic resources in the same manner as the Game and Fresh Water Fish Commission.
