Impact of water level fluctuations on lacustrine groundwater discharge and groundwater-borne nutrient import into lakes

Key Points

• Nutrient import is influenced significantly by groundwater discharge fluctuations, highlighting essential ecological dynamics.
• Groundwater discharge rates varied throughout different water levels, showing a correlation with nutrient levels entering lacustrine systems.
• Observational analysis across multiple lakes identified patterns in biogeochemical processes related to water fluctuations.
• Findings may enable better management of freshwater ecosystems by understanding nutrient dynamics especially during seasonal changes.
