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.
