Grassed waterways are an excellent way to prevent persistent gully erosion in small draws that have a slope of around 1.5% or more. These waterways are best maintained throughout the season with regular mowing, if possible. It is also important to till up to, but not across or parallel to the waterway (as the photo above shows). This way run off from the fields drains quickly away through the grassy area where it can be absorbed or runoff without the risk of creating deeper gullies. Tilling or planting parallel to the waterway actually prevents water from entering the waterway, and what happens is a new gully will form along the edge of the waterway: exactly what we don't want happening.
Grass waterways can save you soil and will save you money. No more filing in gullies with valuable topsoil only to see it wash away again after the next big storm.
