P-557-420-SZSZ GLEN CANYON UNIT, hatchery truck at Lees Ferry, Arizona

Abstract

Rainbow trout by the thousands pour out the discharge tube attached to the hatchery truck at Lees Ferry, Arizona, as the first fish planting in the clear water below Glen Canyon Dam begins. Altogether 9,600 trout, averaging eight inches in length, were planted in this one brief operation, which is the first of many scheduled for this stretch of river. The fish were raised in the U. 5. Fish and Wildlife's Willow Beach Hatchery at Willow Beach, Arizona. Trout can now survive in the once-muddy Colorado River because Glen Canyon Dam has cleared the sediment from the water. Also, the cold water emerging from the lower levels of the reservoir (Lake Powell) is ideal for trout.
