To avoid this problem, make sure to use sound conservation strategies on the land above the waterway. At the first sign of a sediment-choked waterway, reshape and reseed the area to ensure proper function. Inspect the waterway outlets. Small gullies can grow into a gulch in a single rainstorm. Install an outlet structure where runoff dumps into a road ditch or other outlet.
Structures are especially important where water drops 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. If the grass stand stays 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. Minimize or eliminate livestock traffic through a waterway because hoofprints are natural erosion starters. If there are burrowing animals, such as badgers, groundhogs or moles, they'll have to be controlled.
