The percentage of groundwater in streams can vary widely depending on factors such as rainfall, geology, and land use. On average, it is estimated that about 40-60% of streamflow comes from groundwater. However, in some regions this percentage can be much higher or lower.
During a prolonged drought, the volume of water that passes from groundwater to streams decreases. This is because there is less water available in the groundwater system due to reduced recharge from precipitation. As a result, streams receive less water from groundwater, leading to lower streamflow levels.
Aggressive extraction of groundwater can deplete underground water sources faster than they can naturally recharge, causing streams to go dry. When groundwater is over-pumped, the equilibrium between surface water and underground water is disrupted, leading to reduced flow in streams that are dependent on groundwater for their water supply. This can have negative impacts on ecosystems, wildlife, and communities that rely on those streams for water resources.
The antonym for groundwater is surface water, which refers to water that is above ground in rivers, streams, lakes, and oceans.
Most of Earth's freshwater is located in glaciers and ice caps, with a smaller amount stored in groundwater. Rivers, lakes, and streams make up a small percentage of Earth's total freshwater supply.
Groundwater systems consist of aquifers, which are underground rock formations that hold water. Groundwater recharge occurs when precipitation replenishes these aquifers. Groundwater flow can move through the aquifer and eventually discharges into streams, lakes, or oceans. Groundwater systems play a vital role in providing drinking water and supporting ecosystems.

Reducing pollution in streams and groundwater helps preserve water quality, making it safer for human consumption and ecosystem health. Conserving water by reducing wastage and promoting efficient usage helps maintain the quantity of available clean water resources in streams and groundwater, ultimately contributing to sustainable water management.
In landlocked lakes, water is primarily discharged through evaporation, groundwater seepage, and rivers and streams that flow into or out of the lake. Precipitation also contributes to the water balance of a lake by adding water to the system.
Groundwater is found underground in porous rocks and sediments, while surface water is found in rivers, lakes, and streams. Groundwater moves very slowly compared to surface water. Groundwater is less susceptible to evaporation, pollution, and temperature fluctuations compared to surface water.
Groundwater depletion can lower the water table, leading to reduced base flow in streams. This decrease in base flow can impact stream ecosystems, aquatic life, and water quality. Additionally, it can increase the risk of stream drying up during dry periods.
