P12-201-4497 NA Klamath Project, OR-CA. 3500 Manitowoc leaving PP EE. This crossing is located on east bank of drain enlargement just north of PP EE outlet transition. This area was of concern due to narrowness of top surface and also looseness of material. This was remedied by cutting down top surface and laying matts on surface. This crossing was made with little or no problems; November 28, 1977; USBR photo by D.J. Kline
