The Fish Ladder PDF Author: Katharine Norbury

Pages : 332

Book Description
Katharine Norbury was abandoned as a baby in a Liverpool convent. Raised by a loving adoptive family, she grew into a wanderer, drawn by the landscape of the British countryside. One summer, following the miscarriage of a much-longed-for child, Katharine sets out-accompanied by her nine-year-old daughter, Evie-with the idea of following a river from the sea to its source. The luminously observed landscape grounds the walkers, providing both a constant and a context to their expeditions. But what begins as a diversion from grief evolves into a journey to the source of life itself: a life threatening illness forces Katharine to seek a genetic medical history, and this new and unexpected path delivers her to the door of the woman who abandoned her all those years ago. Combining travelogue, memoir, exquisite nature writing, and fragments of poems with tales from Celtic mythology, The Fish Ladder has a rare emotional resonance. It is a portrait of motherhood, of a literary marriage, a hymn to the adoptive family, but perhaps most of all it is an exploration of the extraordinary majesty of the natural world. Imbued with a keen and joyful intelligence, this original and life-affirming book is set to become a classic of its genre.

Pages : 70

Book Description
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).

Pages : 108

Book Description
Facilities for passing fish upstream over John Day Dam include a powerhouse collection system with fishway entrances at each end and along the downstream face of the powerhouse, and a 24-ft-wide fish ladder with 1-on-10 slope on both sides of the river. The north fish ladder (except entrance section) and a portion of ladder adjacent to the south fish counting station were studied in a 1:10-scale model. A group of four typical diffusion chambers in each ladder was reproduced in a 1:8-scale model. Fishway weirs with 6-ft-long overflow crests at each end of a 12-ft-long nonoverflow section, upstream fins, and 18- by 18-in. orifices at the floor were adopted. Orifice sizes in the regulating sections were adjusted to control discharge and head drops between 19 nonoverflow bulkheads for an 11-ft range in forebay levels. Sloping floors, baffle beams at a constant elevation, and metering orifices sized to provide 60 cfs each were selected for diffusers in sloping portions of the fish ladders.

The Founding Fish

The Founding Fish PDF Author: John McPhee
Publisher: Farrar, Straus and Giroux
ISBN: 0374706344
Category : Nature
Languages : en
Pages : 368

Book Description
John McPhee's twenty-sixth book is a braid of personal history, natural history, and American history, in descending order of volume. Each spring, American shad-Alosa sapidissima-leave the ocean in hundreds of thousands and run heroic distances upriver to spawn. McPhee--a shad fisherman himself--recounts the shad's cameo role in the lives of George Washington and Henry David Thoreau. He fishes with and visits the laboratories of famous ichthyologists; he takes instruction in the making of shad darts from a master of the art; and he cooks shad in a variety of ways, delectably explained at the end of the book. Mostly, though, he goes fishing for shad in various North American rivers, and he "fishes the same way he writes books, avidly and intensely. He wants to know everything about the fish he's after--its history, its habits, its place in the cosmos" (Bill Pride, The Denver Post). His adventures in pursuit of shad occasion the kind of writing--expert and ardent--at which he has no equal.
