Steep Eroded Banks
Steep Eroded Banks
Bank erosion is a problem that happens in some parts of our streams. What causes stream bank erosion could be a result of: steep hills, lack of bank vegetation, and human impacts. Erosion damages fish habitat by damaging spawning grounds, excessive siltation caused by erosion covers gravel used for spawning. Bank erosion also increases the width of the stream decreasing flow and decreasing depth.

Grade the bank
Grade the bank
By sloping our bank to 45 degrees it will stop the bank from eroding further and adding sediments to the water, destroying the fish habitat in catfish creek.

Lack of buffer strip
Lack of buffer strip
A buffer strip is an area of land with vegetation that influences the water quality of the creek. Buffer strips trap sediment and enhance filtration by slowing down runoff that enters the creek. Buffer strips also prevent erosion by stabilizing the stream bank. Without buffer strips banks erode water quality drops and creeks become choked with sediments.
lack of overhanging vegetation
lack of overhanging vegetation
Stream shading and overhanging vegetation influence the temperature of creeks and the base of the food chain. Overhanging vegetation shades the creek lowering overall temperature. Vegetation also provides detritus (dead organic matter) for the base of the food chain.

Plant more vegetation
Plant more vegetation
Planting more vegetation along stream banks helps protect against erosion and sedimentation so by planting more buffers along the stream bank it protects the fish habitat from being destroyed.

In a stream you need about 75% stream cover to control the temperature of the water. Water temperatures need to remain cool throughout the year so that cold water species such as trrout can survive.
