Reservoir Dam Outlet and Spillway Inspection

Inspection template for supply reservoir dams, outlet works, and spillways to assess structural condition, seepage, debris accumulation, and operational readiness for dam safety.

Inspection Details

• Inspection date and time recorded
• Inspector name and role documented
• Dam name, location, and asset ID verified
• Weather and recent rainfall conditions noted
• Inspection scope completed for dam, outlet works, and spillway

Dam Crest, Embankment, and Abutments

• Crest, embankment, and abutments show no visible settlement, cracking, sloughing, or deformation
• Surface erosion, animal burrows, sinkholes, or depressions observed
• Vegetation, trees, or root intrusion affecting embankment or sightlines
• Access roads, crest walkway, and inspection points are safe and passable
• Any new cracks, slumps, or movement compared with prior inspection documented
• Overall dam crest and embankment condition rating

Seepage, Drainage, and Toe Conditions

• No uncontrolled seepage, piping, boils, or wet areas observed on downstream face or toe
• Seepage quantity and location documented where present
• Drainage features, toe drains, and relief wells are functioning and unobstructed
• Evidence of erosion, sediment transport, or muddy discharge at seepage points
• Toe area free of standing water, sinkage, or saturated ground that indicates instability

Outlet Works, Gates, and Appurtenances

• Outlet conduit, intake, and appurtenant structures show no visible cracking, corrosion, or displacement
• Trash rack, screens, and intake openings are clear of debris and blockage
• Outlet gate, valve, or control mechanism operates smoothly through full travel
• Gate stem, actuator, handwheel, seals, and visible hardware are intact and secure
• Leakage, unusual vibration, or abnormal noise noted during operation
• Outlet works condition notes

Spillway and Energy Dissipation

• Spillway channel, crest, and sidewalls are free of obstruction, cracking, spalling, or undermining
• Debris, sediment, woody material, or ice accumulation affecting spillway capacity
• Energy dissipation structure, apron, stilling basin, or plunge pool shows no scour or displacement
• Spillway approach and downstream discharge area are stable and free of erosion

Documentation, Deficiencies, and Closeout

• Photos captured for all deficiencies and notable conditions
• Deficiencies, non-conformances, and immediate hazards documented with location and severity
• Corrective actions, responsible party, and target completion date recorded
• Inspector signature completed
• Overall inspection result
