To avoid that, use sound conservation strategies on the land above the waterway. At the first sign of a filled-in waterway, reshape and reseed the area to ensure proper function. Also, inspect the waterway outlets. Little gullies can evolve into a gulch in a single rainstorm. Install a waterway outlet structure where runoff falls into the road ditch or other outlet.
Structures are especially important where when water falls from one level to another.
Get help from the local conservationist in designing an outlet structure that will prevent gullies and gulches from cutting back into the waterway. There are more tips for keeping a waterway healthy. If the grass stand is poor, try to fertilize the grass periodically and evaluate the results. Inspect the area frequently and repair minor rills or gullies by reshaping and reseeding. Wet seasons can dramatically point out the necessity for sufficient waterways, Miller said.
