These ongoing studies are de- signed to reduce deep percolation of irrigation water and seepage from farm ditches. Improvements consist of lining some existing farm ditches and placing other ditches in pipe. Water measuring devices and flow control structures are being installed on the improved conveyance facili- ties. Up to approximately 665 miles of on-farm ditches may be lined or 7
