| Description | Sediment cores were collected from Walupt Lake, Loon Lake, and Wannacut Lake as part of a long-term study evaluating mercury trends through sediment cores across Washington State. Mercury concentrations at Walupt Lake are low, and recent levels represent a decline over previous measurements. Mercury analyses throughout the cores indicated peak flux rates at Loon Lake occurred during the early 1990s and have since declined. Peak fluxes at Wannacut Lake took place in the early 1930s concurrent with hard-rock mining in the drainage basin. Flux rates declined after mining stopped, and current levels are similar to Loon Lake. |
