📒Fish Ladders For Lower Monumental Dam Snake River Washington ✍ Louis Z. Perkins
✏Fish Ladders for Lower Monumental Dam Snake River Washington Book Summary : Facilities for passing fish upstream over Lower Monumental Dam include a powerhouse collection system and a 16-ft-wide fish ladder on both sides of the river. A straight, 35-pool section of fish ladder and a typical fishway entrance weir were reproduced in a 1:10-scale model. Performance of a pair of typical diffusion chambers was studied in a 1:8-scale model that included portions of the adjacent supply conduit and fish ladder. Fishway weirs of original design, with 5-ft-long overflow crests at each end of a 6-ft-long nonoverflow section, upstream fins, and 18- by 18-in. orifices on the floor, were satisfactory. Discharges of 66.0 and 69.7 cfs produced heads of 10.0 and 12.0 in. on the weirs. With standard orifices in all weirs, heads of 12.2 and 13.4 in. on the first weir below the fish counting station were required to provide the above discharges. (Modified author abstract).
📒Lower Monumental Dam Snake River Washington ✍ Alvin J. Chanda
✏Lower Monumental Dam Snake River Washington Book Summary : Lower Monumental Dam is located 41.6 miles above the mouth of the Snake River and 35 miles northeast of Pasco, Washington. Maximum heat on the project is 103 ft; the project design discharge is 850,000 cfs. Excavation requirements, diversion plans, structures locations, and methods of operation were studied in a 1:100-scale model that reproduced 2.4 miles of river channel and pertinent overbank topography. The first-step cofferdam and diversion channel were designed to protect the work area against discharges to 250,000 cfs. The diversion channel and cofferdam cells were revised and the location of a temporary fishway was determined by means of the model study. Tests of the second-step cofferdam, designed for 200,000 cfs, indicated that the height of four upstream cells should be increased 3 ft, the three downstream temporary fishway entrance.
