Dam Basics. The purpose of a dam is to impound store water, wastewater or liquid borne materials for any of several reasons, such as flood control, human water supply, irrigation, livestock water supply, energy generation, containment of mine tailings, recreation, or pollution control. Many dams fulfill a combination of the above functions.

A dam is a barrier that impounds water and generally serves the primary purpose of retaining water. Wisconsin law defines a dam as any artificial barrier in or across a watercourse which has the primary purpose of impounding or diverting water and includes all appurtenant works, such as a dike, canal or powerhouse.

Other Water Retaining Structures. A number of structures that retain water are not licensed under the Water Sustainability Act. The Dam Safety Regulation does not apply to those structures. Mining. Dams on a mine site that require a water licence may be regulated under the Water Sustainability Act and Dam Safety Regulation.

Councils Responsible Gold Mining Principles, which have recently come into effect for World Gold Council members. This recognition may well be one of the reasons that the environmental risk of tailings management rose to the top 10 risks, likely driven by uncertainty around regulatory changes and the future impact of mining practices
On a global scale, the demand for mineral products has increased substantially with economic development. Consequently, the mining of mineral resources results in the production and accumulation of a large number of tailings, causing many problems with respect to mining, the environment, and the economy. In the mining process, tailings must be reasonably treated to prevent them from entering ...

Environmental regulations are also advancing, placing more stringent requirements on the mining industry, particularly with regard to tailings storage practices. This ultimately places added pressure on the operators of a tailings facility who carry out the day to day roles of tailings discharge and water management.
Summary. A tailings dam failure at the Mount Polley Mine occurred on August 4, 2014 resulting in the loss of about 17 million cubic meters of water and 8 million cubic meters of tailingsmaterials into Polley Lake, Hazeltine Creek and Quesnel Lake having significant impact.
a dam that is not on a watercourse and that holds less than one megalitre of water or a dam constructed for the primary purpose of storing waste as defined in the Act. In addition to a barrier across a watercourse, a dam includes an excavation in a watercourse and a flood levee, both of which also require a permit under the Act.

The most common type of timber retaining structure is the timber crib. A crib structure is made by placing a number of criblike cells together and filling them with soil or rocks to give them strength and weight. The cribs in retaining walls are made with timber, and the cells are filled with earth to form a gravity retaining
