Waterwheel Microhydro P1, The Dam

This is the first part of my waterwheel series. In this video and subsequent videos I go over the construction of a dam, flume, waterwheel, and electrical system for my little microhydro scheme.


  • Minimum Flow: 10 GPM
  • Maximum Flow: 1000+ GPM
  • Designed operating flow: ~50 GPM
  • Designed water drop (head): 32″
  • Desired wattage output at 12V: Peanuts, or somewhere between 5W and 20W continuous output.
