Abstract Four cores from Kootenay Lake have been dated using 2l0Pb. These cores have also been analyzed for total Pb concentration specifically to compare the sediment record with the known history of lead-zinc mining around the lake. Two sorts of impact on the lake are recorded in the sediments. First, there is obvious contamination by Pb in which concentrations within cores parallel the regional “boom-and-bust” mining history. Second, the sedimentation rate appears to have been affected by damming of the inflowing rivers and probably also by logging and the associated road construction in the watersheds. Spatial variability within the lake sediments is evident: sedimentation rate is highest towards the north and south ends of the lake where river inflow is greatest; contamination by Pb is highest in the middle of the lake close to the major mining activities.
