Best Practices for Tailings Dam Design - KCB

Sep 07, 2017 · Background. Recent major tailings dam failures have led to an industry-wide review of the design and management of tailings storage facilities. Before the 1960s, mine tailings were often disposed directly into ponds, lakes, rivers or natural topographic depressions, or stored in impoundments supported by earthen dams, without necessarily applying engineering principles (McLeod et al. 2015).

Eels: New Zealand freshwater fish - Department of Conservation

Culverts and dams can also impact on eels by preventing their migration. Eel habitat is also impacted by pollution. Sewage and effluent from meat works and pulp and paper plants discharged into rivers can remove large quantities of oxygen from the water. The result of this oxygen depletion is that the fish will either die or move away.
