How does the rainfall affect the rivers and lakes?

Rainfall significantly impacts rivers and lakes by replenishing their water levels, which can enhance aquatic habitats and support local ecosystems. Increased rainfall can lead to higher river flows, potentially causing flooding and erosion. Conversely, insufficient rainfall can result in lower water levels, affecting water quality and availability for wildlife and human use. Overall, the amount and intensity of rainfall play a crucial role in maintaining the health and stability of freshwater systems.
