Skaneateles and Oneida lakes are both glacially-formed lake basins in Central New York State that are important regional water resources utilized for drinking water as well as recreation. Skaneateles Lake is the primary water source for the City of Syracuse, and Oneida Lake is the largest lake entirely within New York State and serves as a water source for several near-by communities. The mechanisms which carved these lake basins vary, resulting in different lake morphologies with significant differences in average depth, width, watershed area, and trophic status. Both have seen varying development within their watersheds. These differences make them unique study sites for comparing how local climate and watershed activities impact nutrient loading in lakes in the same temperate, deciduous zone. Sediment in both lakes archive environmental and climatic conditions during and since the last North American deglaciation (Muller & Calkin, 1993; Mullins & Hinchey, 1989). Short cores were collected in the summer of 2022 from both lakes which capture sediment deposited over the last few hundred years (Figures 1 & 2). In this study we use sediment cores to examine the record of changing environmental conditions through time in two end-member lakes and established a baseline record of sediment nutrients entering the lakes from the late 1600s to present.
