Detailed explanation-1: -The water in lakes comes from rain, snow, melting ice, streams, and groundwater seepage. Most lakes contain freshwater.

Detailed explanation-2: -Lakes are supplied with water by rainfall that falls directly on the surface of the lake, by water run-off from the adjacent land and small streams, or by groundwater that seeps through the soil to the lowest point which is the lake.

Detailed explanation-3: -There are two primary sources of water – surface water and groundwater.

Detailed explanation-4: -Ninety-eight percent of Earth’s available fresh water is groundwater. It is about 60 times as plentiful as the fresh water found in lakes and streams. Water in the ground travels through pores in soil and rock, and in fractures and weathered areas of bedrock.
