Solution: Grass Waterways

Grass Waterways:  Shaping a natural drainageway and establishing grass to prevent gullies from forming in fields.

How it Works

A natural drainageway is graded and shaped to form a smooth, shallow channel and then planted to sod- forming grasses. The drainageway carries runoff water from the field and the grass prevents the water from forming a gulley. The vegetation may also trap some sediment washed from cropland, absorb some chemicals and nutrients in the runoff water, and provide cover for small birds and animals.

Planning

• The width and depth of the waterway will depend on the nature of the fields it drains.
• A grade stabilization structure may be needed at the bottom of the waterway to prevent a gully from forming.
• Use soil conservation measures on the fields to prevent siltation of the waterway.
• Significant land reshaping might be required in some situations.
• Establishing good cover quickly is critical. Tile drainage, mulching or other temporary cover might be needed until grasses are established.

Maintenance

• Lift equipment out of the ground and shut off spray equipment when crossing the waterway.
• Do not use the waterway as a roadway.
• Fertilize if needed and mow periodically, but wait until after July 15 when birds are done nesting.
• Be careful not to till into the edges of the waterway.
• Avoid end rows planted along the waterway, because they may allow gullies to form on the waterway edge.
