~ Grassed Waterway

Grassed Waterways are strips of grass seeded in areas of cropland where water concentrates or flows off a field.  Benefits of grassed waterways are the shaping of a natural drainageway and establishment of grass to prevent gully erosion and the formation of gullies in fields. The natural channel carries water runoff from the field while the grass prevents the water from forming a gully. Vegetation amongst the waterway may also trap sediment washed from cropland, absorb some chemicals and nutrients in the runoff water and provide cover for small birds and animals. Grass waterways are easier to cross with farm machinery than are natural gullies.
