Materials for Harrold Projects

Water moves across this country with force, and coarse stone is what holds a slope, a swale or a bank in place. Riprap is the big angular rock for culvert outlets, dam faces, spillways and shoreline.

Large river rock suits draw bottoms and dry creek beds, where heavier rounded stone slows a channel and spreads the flow. Large River Rock is the piece to start with when a bank keeps cutting back.

Below the coarse end, #4 crushed stone handles heavy drainage, approaches and trench bottoms in wet ground. It is a 1 1/2 inch clean rock.

#4 Crushed Stone sits well in a swale that has to stay open through the spring thaw.

For tighter work, 3/4 quartzite is the hard pink stone from the southeast, good for drives, drainage beds and landscape stone. 3/4 Quartzite takes a beating on a slope that sees runoff.

Where a cushion course goes under concrete or asphalt, gravel cushion is the South Dakota term.

Gravel Cushion also works as the crushed top course on a gravel drive.

For the fine end, washed rock is the clean drainage stone used in drain tile, drywells, sump runs and window wells. Washed Rock carries water instead of holding it.

Ground and Conditions in Harrold

The working season here runs between the spring thaw and freeze-up, and wind and drifting stay a factor well into spring and again from late fall. Time a delivery around that window rather than against it.

Across the Missouri Coteau the ground is stony glacial till over Pierre shale, jumbled into knobs and closed kettles with gravel in the kames. Water has nowhere to run, and the shale under the till stops what does soak through.

That is why low ground stays saturated and why drainage stone earns its place on a site here. On the open knobs, wind scour strips exposed ground, and runoff cuts the steeper slopes.

Frost heave and the spring thaw move exposed ground, and gumbo ground is the slow-draining shale country west of the river. Exposed slopes and low spots take the worst of it.
