Groundwater significantly impacts small lake water quantity and quality.
Groundwater can impact the amount and quality of surface water. A study at Osongji Lake in Korea analyzed water levels, chemistry, and isotopes to see how groundwater affects the lake. Groundwater entering the lake doesn't always match rainfall, suggesting a delay. The lake's water chemistry is influenced by groundwater. The isotopic composition of the lake water changes with the seasons, showing varying groundwater contributions. This research demonstrates how water data can reveal changes in groundwater's impact on surface water over time.
