Earthen, wooden, concrete or other structure built within a natural or man made channel to prevent gully development and bed erosion while improving water quality and habitat conditions.
How it works
A grade control structure is used to stabilize a stream, grassed waterway, or gully to reduce channel bed erosion. This practice is used at sites where the flow velocity or the concentration of water in a channel or gully requires a structure to stabilize the grade or to prevent head cuts from migrating upstream.
How it helps
Stabilizes the grade and controls erosion in natural or artificial channels
Prevents gully head cut formation and channel bed erosion by lowering water in a controlled manner
Enhances environmental quality and reduces pollution hazards
Manages channel flow line for non-erosion benefits, including fish passage, water table control, and reduced turbidity
Are ESA considerations or special permits required?
Are adequate conservation practices installed above the structure to prevent sedimentation?
Is the planned location in the proper place to achieve the level of control you want?
Ask your conservation planner for design and construction specifications.
The landowner must obtain any necessary easements or permits.
Avoid operating farm equipment too close to the structure.
Maintain good vegetative cover on all slopes and water courses.
Control livestock access to the structure.
Remove debris accumulation at the structure and immediately upstream or downstream.
