Overview
• Dams are Potential Storage Devices
• Design Based on Water Pressure – 33 ft = 14.7 psi
• Keys - Head (height) and Water Quantity
• Material – Dependent on Type and Head
• Spillways – excess water – prevent overtopping
• Water Conductors – Piping or Penstock
• Power House – Electric Generators
