(a)

Removing brush and trees from the Dam;

(b)

Control of burrowing animals, especially nutria near the Dam or reservoir, including filling deep burrows;

(c)

Restoration of areas of surface or wave erosion, and taking measures to prevent future erosion;

(d)

Adding or moving fill to restore Crest Height and width;

(e)

Clearance of soil, rock, vegetation and debris from the Spillway;

(f)

Proper cycling and lubrication of Valves and Gates at least once a year, unless otherwise specified in a maintenance and operations plan approved by the Department;

(g)

Patching, sealing, or replacing areas of cracked concrete on the Dam;

(h)

Removing debris, rock, or earth from the inlet and outlet of penetrating Conduits and drains;

(i)

Repair or replacement of worn or damaged parts of Gates or Valves;

(j)

Ensuring access to the Dam is sufficient for inspection, repair and emergency actions, and that unauthorized access is controlled;

(k)

Securing operating equipment such as Valve controls and Spillway controls;

(l)

Evaluation of the Conduit and taking necessary actions to ensure the Conduit is not compromised, including patching pipes with minor corrosion; and
