“Our property backs up to a side channel off the McKenzie near McKenzie Bridge, and snowmelt used to carve a new path through the yard every spring. We lined a swale with three tons of large river rock last fall to slow the water down and spread it out. Through this year's runoff the channel stayed put instead of migrating toward the barn like it used to.”

- Color
- Tans, grays and browns
Winter saturation in the Willamette Valley can leave exposed runoff routes looking temporary unless they are finished as part of the landscape. Large River Rock brings naturally rounded stone to a planned dry runoff course, giving the feature enough visual presence to remain distinct beside planted ground or a road edge. Its smooth surfaces suit a border around a constructed water feature as well.
Where seasonal water crosses a slope or collects near a landscape edge, these stones can also serve as visible erosion control. Shape the runoff route before placing Large River Rock, then use the stone as the exposed lining so the course reads as an intentional part of the finished site. This approach is useful where wet-season water needs a clear route through clay ground.

Common Uses
Dry Creek Beds
Create the look of a seasonal creek channel with large river rock, adding texture and definition to the landscape. Follow an existing swale or lay out a curving channel as a focal landscape element.
Ponds & Water Features
Use large river rock along the edges of ponds, waterfalls, and fountains, creating a stone border that helps built water elements sit naturally within the landscape.
Erosion Control
Because these stones are large and heavy, they can help hold material in place on slopes, banks, and along water edges where flowing water could move smaller rock.
Landscape Accent Features
Set large river rock in planting areas, near entrances, or around individual plants as noticeable accents. Its scale gives the eye a place to rest within the landscape.
Why Choose Large River Rock
Strong Landscape Contrast
With its 2 to 4-inch scale, large river rock adds pronounced texture and visual contrast to landscape layouts. It can mark focal areas and give ordinary outdoor spaces more definition.
Landscape Stone
In landscape settings, large river rock does not rot or decompose. Its color and form remain in place rather than breaking down as organic ground covers do.
Stays in Place
After installation, large river rock's weight helps it remain where it is placed. It is less likely than lighter materials to move with wind, flowing water, or pedestrian use.
Naturally Rounded Character
Water shapes large river rock into individually varied, rounded stones. This natural texture and range of forms offer an appearance distinct from manufactured landscape materials.
Frequently Asked Questions About Large River Rock

Solved erosion behind our storage yard for good
We operate a small equipment rental business near Gold Hill along the Rogue, and every winter the runoff off the hill behind our storage yard cut a deeper groove toward the fence line. Last fall we addressed it with six tons of large river rock laid in a shallow channel over fabric, sloped to carry water toward the ditch instead of pooling against our fence posts. Oregon Rock Supply's driver worked the tandem down a tight access road and dumped it in two spots where we'd marked with stakes. Through a full winter of rain the channel has done its job, no new gouges and no water against the building.

Nice border along the dry creek bed
Built a dry creek bed border along the side yard near Reedsport where the Umpqua fog keeps everything damp most of the year. Four tons of large river rock did the job, mixed with some smaller stone for texture. Delivery ran a bit past the window since our road is a long haul from the yard, but the driver still got it here the same afternoon.

Swale holds up along the McKenzie
Our property backs up to a side channel off the McKenzie near McKenzie Bridge, and snowmelt used to carve a new path through the yard every spring. We lined a swale with three tons of large river rock last fall to slow the water down and spread it out. Through this year's runoff the channel stayed put instead of migrating toward the barn like it used to.

Good size for the outfall project
Client near Harrisburg had a downspout outfall eroding a hole in the lawn every winter, so we placed two tons of large river rock in a shallow basin to break up the flow. Looks clean and has held together through a wet season already. A few of the rocks were on the smaller end of the range, closer to two inches, which made the bed look a little thinner than we planned.

Erosion fix worked in one weekend
Water from the downspout kept cutting a gully at the edge of our yard near Rogue River. A ton of large river rock laid over fabric stopped it cold. Looks natural, and it hasn't budged through one soggy winter.
