ANS:Effective
erosion-control practices on lands surrounding streams are important to help maintain clear,
clean water. It is also important to prevent silt or chemical pollutants from entering streams.
Maintaining stream-side forestation is important in regulating stream temperatures during the warm
summer months. Some species of fish stop feeding and may even die when stream temperatures
become too high. The amount of dissolved oxygen in warm water is also much lower than it is in cold
water. Without adequate oxygen, aquatic wildlife die.
