Ditch & Culvert Cleanout in Western South Dakota

Ditches and culverts only work when water can get through them. Over a few seasons they fill with silt, cattails, tumbleweeds and debris, and the water backs up into fields, yards and roads. Black River Contracting cleans out ditches and plugged culverts across Western South Dakota and Northeast Wyoming.

Our Cat 324E long-reach excavator digs from the bank, so it can clean a ditch without driving down into it and reach the ends of a culvert from the road or the field above.

Ditch cleaning

  • Drainage ditches along fields, yards and roads that no longer carry runoff away.
  • Irrigation ditches and canals that have silted in or grown over.
  • Road ditches for landowners, towns and counties.

We dig the ditch back to its line and grade, and place the spoil where you want it, spread along the bank or hauled away.

Culvert cleanout

  • Plugged inlets and outlets cleared of silt, debris and growth.
  • Outlet repairs: reshaping the channel and placing riprap where water leaving the pipe has cut a hole.
  • Pipes past saving: if a culvert is crushed, rusted through or too small, we’ll tell you and can replace it.

We call in utility locates before we dig, since buried lines often run along ditches and roads.

Common questions

How much does ditch cleaning cost?
It depends on the length of ditch, how much silt and growth is in it, how far the machine has to reach, where the spoil goes and how far we travel. We look at the ditch with you and quote that job.
Can you clean a ditch that has water in it?
Usually. The long-reach excavator works from the bank and reaches into the ditch, so it doesn't need to be bone dry. Low water makes for cleaner digging and drier spoil.
Can a plugged culvert be cleaned out, or does it need replacing?
Many can be cleaned out, especially when the problem is silt and debris at the ends. If the pipe is crushed, rusted through or too small for the water it gets, it's usually time to replace it.
Who owns the culvert under my road?
It depends on the road. Culverts under county and state roads belong to the county or the state, and they should be asked before anyone works on them. Culverts on private drives and field approaches usually belong to the landowner.
