Unpopular opinion: skip the fancy French drains and save your cash

I dropped $2,800 on a contractor-installed French drain system in my Edmonton backyard last spring and it clogged up within 3 months anyway from all that clay soil. Has anyone else had better luck with a simple surface trench or gravel pit instead?

You're spot on with the gravel trench idea. I've noticed a bigger pattern here - we get sold on the most complicated, expensive fix first when the simple solution does the job just as well or better. It's like how people buy a $400 stand mixer when a good whisk and some elbow grease would work for most home baking. The French drain industry has convinced everyone you need pipes and filters and fabric, but the clay just laughs at all of it. A wide gravel pit gives the water room to spread out and find its own path down, which is exactly what nature does anyway in a swamp or wetland. Sometimes the old school methods win because they work with the soil instead of fighting it. Good on you for saving folks some cash and headaches.

Oh man, the clay soil struggle is so real out here in Alberta. I've seen a ton of folks in Calgary post about the same thing, and honestly, the fancy drain systems just don't hold up against that sticky clay. What nobody talks about is just digging a wide trench and filling it with coarse 3/4 inch gravel, no pipe needed. That lets the water spread out and soak in slowly instead of trying to channel it somewhere. Plus it's like $50 in materials instead of thousands, and when it gets muddy you just throw in more gravel. Way simpler, way cheaper, and in my experience it actually works better long term.

Another idea is mixing in some lime with the gravel to break down that clay over time.
