  Osceola Machine Works’ unique products are a quick & easy solution to your water control structure needs. At Osceola Machine works, we have successfully combined proven water control methods with our innovative patent pending coupling system.


  Every flashboard Riser, Flapgate or Screwgate is sized to fit your culvert. Often “one size fits all” really means you will be left to your own devices to “make it fit”.


  Osceola Machine Works’ all steel design fits directly to your corrugated steel, polyethylene (plastic) or custom fitted to fit any culvert pipe. Our proven design never requires any welding, concrete or any modification. Often those additional “small print” installation steps cost more than the water control structure.
