The Importance of Dry Dams on the Farm

What 4.4 Inches of Rain Taught Us

Monday, we received 4.4 inches of rain, most of it overnight as heavy storms moved through. By Tuesday, I checked our dry dams to make sure everything was holding.

The result was simple but telling- very little water had collected.

That dam captures runoff from more than 10 acres of fields covered in 2-foot-tall ryegrass. Instead of running off, the water soaked in. Our soils handled 4.4 inches of rain in a single day with minimal runoff.

That doesn’t happen by chance.

At Fischer Farms, we focus on building soil that functions. Through regenerative practices like keeping living roots in the ground and maintaining year-round cover, we’ve created soils that act more like a sponge- absorbing rainfall, reducing erosion, and holding water for when crops need it.

Ryegrass plays a big role in that system. Its deep, dense root structure adds organic matter and strengthens soil structure, improving both water infiltration and long-term resilience.

Later that day, I drove past fields that had already been tilled and planted. Many had visible erosion from the storm. Bare soil simply can’t handle that kind of rainfall the same way.

This time of year, it’s easy to feel behind when others are planting and we’re still waiting to harvest ryegrass. But moments like this are a reminder that soil health is the priority.

Because when the rain comes, the results speak for themselves.
