“Farm up on the Camas Prairie above Craigmont, and every spring the creek that cuts through the north forty would eat another foot or two off the bank, taking good wheat ground with it. Twenty tons of riprap went in along the worst hundred feet, ordered through Idaho Rock Supply after the local quarry quoted three weeks out and we didn't have that kind of time before spring runoff hit. The tri-axle made two trips in one day and the driver placed it exactly along the toe of the bank like we walked him through. Two runoff seasons later, the line hasn't moved and we haven't lost another foot since.”

Size and Grading
- Size
- 4 inches to 12 inches and up
- Type
- Large, heavy stone
After placement, Riprap leaves a substantial stone surface at an Idaho irrigation ditch, shoreline, bank, or runoff route that needs erosion protection. It is made for areas where flowing water can work against exposed soil and displace lighter aggregate. This material fits drainage channels and the ground below culverts, as well as slopes that receive concentrated runoff.
Conditions vary from freely draining ground in the Treasure Valley and Snake River Plain to water-holding loess in the Palouse and clay in the Panhandle. Look at the route water takes across the site before deciding where protection is needed. Use Riprap at the exposed part of that route, particularly where irrigation water or runoff meets bare ground. Its role is surface armoring, not general base material. Where the project calls for smaller erosion-control stone or a heavy base layer, compare crushed stone suited to that separate use.

Pond dam holding strong after spring melt
Twelve tons of riprap faced the downhill side of our stock pond dam out past Soda Springs. We'd lost a chunk of the bank two years running before this went in. The rock locked together better than the broken concrete a neighbor used on his dam, and it came through this year's snowmelt without so much as a slump.

Good rock, driver came late in the window
Nine tons of riprap for the bank along an irrigation return ditch near Homedale, close to the Snake River. Delivery window was noon to four and the truck didn't roll in until almost six, which pushed my afternoon plans back. The rock itself is exactly the size we needed and has held through one full irrigation season already.

Creek bank stopped eating into the wheat field
Farm up on the Camas Prairie above Craigmont, and every spring the creek that cuts through the north forty would eat another foot or two off the bank, taking good wheat ground with it. Twenty tons of riprap went in along the worst hundred feet, ordered through Idaho Rock Supply after the local quarry quoted three weeks out and we didn't have that kind of time before spring runoff hit. The tri-axle made two trips in one day and the driver placed it exactly along the toe of the bank like we walked him through. Two runoff seasons later, the line hasn't moved and we haven't lost another foot since.

Watched that bank slump for years
been watching that ditch bank along the Big Lost River slump into the water more every spring since my kids were small, and this fall we finally piled riprap along it so my grandkids won't watch it slide too.

Shoreline finally stopped eroding into the lake
Eight tons of riprap went in along the shoreline below the cabin out at Sagle, where wave action off Lake Pend Oreille had been chewing into the bank for years. The tri-axle came right down the access road and dumped it in stages so we could place the biggest rock at the waterline first. One full winter of ice and wake from boat traffic, and the bank hasn't lost another inch.
