Bullhead Lake and Silver Lake Sediment Cores 1995

Purpose

Deep hole Bullhead Lake sediment core and west basin Silver Lake sediment core.

Outcome

Bullhead Lake: "A sediment core was collected from the deepest area of the lake on 30 September 1991. The core was collected with a piston core with a plastic tube having an inside diameter of 8.8 cm. The core was sectioned into 1 cm intervals for the first 20 cm and 2 cm intervals to the bottom of the core which was 70 cm. The core was dated by the 210Pb method and the CRS model used to estimate dates and sedimentation rate. The diatom community was analyzed to assess changes in nutrient levels and changes in the macrophyte community and geochemical elements were examined to determine the causes of changes in the water quality."
