Repairs are not intended to significantly increase hydraulic efficiency or capacity of the ditch. The term "repair", means to restore all or a part of a drainage system as nearly as practicable to the same condition as originally constructed and subsequently improved.
Open ditch repairs include minor work such as spraying for weeds and brush, removal of isolated silt deposits, bridge or culvert cleaning, removal of vegetation, debris or other obstructions, fixing isolated side slope damage due to sloughing, fixing damage to culverts and fixing or installing erosion control structures.
Repairs may also involve more extensive cleaning of the ditch bottom of silt deposits to bring the grade line and bottom width to originally constructed or subsequently improved conditions.
Repairs on tile lines include repair or replacement of underground tile as well as the tile intakes and outlets.
