I'm dealing with a stream in my backyard that flows for about 4-5 months each year, and it's causing some soil erosion. The previous owners just dumped river rock along the stream, which has now become embedded in the soil, making it impossible for me to dig a proper trench for a French drain using handheld tools. I even tried renting a push trenching machine, but that didn't work either.
So here's my question: can I create the French drain without digging a trench? My idea is to build around the landscaping fabric and add soil to effectively "create" a trench above it. The stream already has a nice slope, and this approach would potentially eliminate the need for retaining walls. What do you think?

It sounds like you've got a tough situation there! Since the stream flows pretty decently, it might be okay to just create a channel to manage the flow. Keep in mind, though, some areas have regulations about working with natural water bodies, so check if you'll need a silt barrier or a permit. Renting an excavator could also be a good option if digging becomes feasible, though it can be a bit pricey.
I hear you—that's a tricky spot! With the gently sloping river, it might actually help if you plant some native species that can tolerate flooding. Their deep roots will help stabilize the soil and fight erosion. You’ll likely need to pull some of that rock to make room for planting or the drain, a pickaxe might be helpful here, or if that doesn’t work, you might need to rent some heavy equipment.
Honestly, I’d suggest just hiring someone with a bobcat for a day to tackle this. It should make quick work of clearing out what you need and setting everything up. Definitely a solid investment for the long-term health of your yard!
