Can rock dams reverse climate change? [video]

I watched this video a few days ago and what they've done is truly amazing.

I live in the Ozarks in SW MO and four of the five acres are hill side littered with rocks.

A few years ago I piled up some of those rocks in an area that was washing out and now it has about 8-10" of soil built up and is covered with mostly weeds growing.

When it cools down (we've had about a month of 100º temps here) I'm going start making rows of rock piles to catch soil and hopefully slow down the erosion and green things up a bit.

The lady in the vid, Valer Austin Clark, has some great lectures and slideshow presentations on YT if you search for her name and sort for 20+ mins. She built some absolutely massive rock dams that survived some huge floods.

Won't it deprive downstream sources of sediment and flow when done at scale?

Seems a lot like the sort of changes beavers install in a river.

Nice video. Appears to go against Betteridge's Law of Headlines since it does reverse climate change in the area (if climate change was making it drier).
