In the context of lake water sources, which is most relevant for seepage lakes?

Seepage lakes are characterized primarily by their water balance, which is heavily influenced by groundwater interactions. These lakes do not receive significant inflows from rivers or streams, but rather, they rely on the surrounding groundwater to maintain their water level. Groundwater infiltration is crucial as it feeds the lake, providing essential water that replenishes the lake's volume and stabilizes its water quality.

Atmospheric gases relate to the gas composition in water rather than direct water sources. Rivers flowing into the lake would be more relevant for drainage lakes that actively receive surface water inputs. Watermelon irrigation is unrelated to lake water sources and does not contribute to the water volume of the lake. Therefore, groundwater infiltration is the most relevant source for seepage lakes, emphasizing their dependency on subsurface water movement for maintaining lake levels.
