More than any other ecological construction project, stream restoration demands precision. Streams must be well constructed and exact in every detail to meet the natural challenges of stream channel movement, persistent erosive forces, and periodic flooding. Given an incorrect angle, a rock vane can increase a stream’s erosive effects upon the opposite bank, while too much of a gap between stones in a flow control structure can result in its degradation and collapse.

For stream restoration projects, Angler Environmental combines deep expertise, rigorous oversight, and years of experience to achieve precise results. Our construction teams are experts in the use of specialized tools that are ideal for stream work. We are able to preserve as much existing forest as possible within a stream corridor by using smaller, more maneuverable equipment. These machines also have smaller buckets and arms to increase the degree of our precision during installation. These lighter machines allow us to reduce overall impact to stream corridors, while crossing streams easily on temporary bridges.

Our stream restoration projects often include:

• Channel realignment
• Streambed reconstruction
• Installation of in-stream structures such as j-hook rock vanes, grade control structures, cobble riffles, and plunge pools
• Grading banks back to non-erosive slopes (also called bank grading or lay back banks)
• Stabilization with erosion control matting and vegetation
• Addition of vegetative buffers along a stream corridor
