Abstract
Cleaver Lake and Horneblende Lake in the Whitesand Watershed were studied for the impact of mining and milling activities. No release of zinc, copper, iron, or manganese was detected in aerated sediment samples and there were reductions in metals, sulphate, calcium, and conductivity, reflecting the eroding stratification.
