Closure plans for open pit mines require the prediction of final pit lake water chemistry. The geochemical models used for water quality predictions make assumptions about the physical and chemical behavior of the water in the lake; however, few pit lakes have been well documented to provide empirical data for model design. The pit lake at the Sleeper Mine has been characterized with regular water chemical analyses and regular, continuous, multi-parameter profiles through the water column. The lake has undergone repeated periods of chemical and thermal stratification, punctuated by rapid turnover events resulting in vertical homogenization within the water column.
