I built a 200 feet stream / creek to make a natural filter system for my pond. Geotextile and epdm pond liner used for this cascading creek. Stones and gravel for realistic look. It was been a very big project. I don't find this project on the Internet. I would like to share to you my experiment. I made a free guide, step by step with pictures. I hope this is useful for someone !
