Idaho Power Company's Fall Chinook Salmon Hatchery
IDAHO POWER COMPANY’S FALL CHINOOK SALMON HATCHERY PROGRAM Stuart Rosenberger, Paul Abbott, James Chandler 1221 W. Idaho St., Boise, Idaho Background The current Idaho Power Company (IPC) fall Chinook salmon program was established to provide mitigation for losses associated with the construction and operation of Brownlee, Oxbow, and Hells Canyon dams which together form the Hells Canyon Complex. IPC’s current mitigation goal is to produce 1 million fall Chinook salmon smolts annually (see Origination of Idaho Power Company’s Hatchery Mitigation Program section for more details). Oxbow Hatchery, funded by IPC and operated by the Idaho Department of Fish and Game, is responsible for the incubation and rearing of up to 200,000 subyearling fall Chinook salmon. The hatchery is located on the Snake River downstream of Oxbow Dam near the IPC village known as Oxbow, Oregon (Figure 1). IPC also contracts with the Oregon Department of Fish and Wildlife (ODFW) for the production of an additional 800,000 subyearling fall Chinook salmon that were originally reared at ODFW’s Umatilla Hatchery and are now reared at ODFWs’ Irrigon Hatchery, both of which are located near the town of Irrigon, Oregon. Fish reared at both Oxbow and Umatilla/Irrigon hatcheries are released into the Snake River directly below Hells Canyon Dam with the exception of brood years 2003 to 2005 in which some of the production was released at the Nez Perce Tribe’s Pittsburg Landing acclimation facility. Similar to other fall Chinook salmon programs in the Snake Basin, Oxbow and Umatilla/Irrigon hatcheries receive eyed eggs from Lyons Ferry Hatchery, as it is one of only two broodstock holding and spawning facilities for fall Chinook salmon in the Snake Basin. -
Steelhead (Snake River Basin) Oncorhynchus Mykiss Gairdneri
Steelhead (Snake River basin) Oncorhynchus mykiss gairdneri Actinopterygii — Salmoniformes — Salmonidae CONSERVATION STATUS / CLASSIFICATION Rangewide: Imperiled/Vulnerable subspecies (G5T2T3) Statewide: Vulnerable (S3) ESA: Threatened USFS: Region 1: No status; Region 4: Sensitive BLM: Threatened, Endangered, Proposed, and Candidate (Type 1) IDFG: Game fish; Threatened BASIS FOR INCLUSION Threatened under the U.S. Endangered Species Act; declining abundance and habitat degradation. TAXONOMY Steelhead are the anadromous life form of rainbow\redband trout Behnke (2002). Steelhead spawning east of the Cascades are considered part of the redband trout of the Columbia Basin, which is a subspecies of rainbow trout. The rainbow trout Oncorhynchus mykiss complex includes 5 additional subspecies. Rainbow trout were originally described by Walbaum in 1792 (Nelson et al. 2004). DISTRIBUTION AND ABUNDANCE Steelhead, which are the anadromous life form of rainbow\redband trout, were historically found along the west coast of North America from southern California to central Alaska. The interior Columbia River basin steelhead ranged from east of the Cascades upstream in the Columbia River and tributary streams to natural geologic barriers such as Shoshone Falls on the Snake River (Behnke 2002). In Idaho, steelhead had access to most of the Clearwater, Salmon, Weiser, Payette, Boise, Owyhee, Bruneau and Salmon Falls Creek drainages. Populations using the tributaries above Hells Canyon Dam were eliminated with the construction of the Hells Canyon complex in the 1950s and earlier upriver dams. Currently, wild and hatchery steelhead are found in the Snake River below Hells Canyon Dam, Clearwater, and Salmon River drainages. The resident life form, inland redband trout, are also present in the Salmon and Clearwater drainage along with steelhead. -
Native Americans, the Earliest Interpreters: What Is Known About Their Legends and Stories of Yellowstone National Park and the Complexities of Interpreting Them
Lee H. Whittlesey Native Americans, the Earliest Interpreters: What is Known About Their Legends and Stories of Yellowstone National Park and the Complexities of Interpreting Them The thermal wonders of the Park did not frighten the native peoples of the region. Euro-Americans originated this idea and it must be dispelled before we can understand the true nature of Yellowstone’s human past. —Joseph Weixelman, “The Power to Evoke Wonder” (1992) hat did the Indians say about Yellowstone? They must have told stories about its strange wonders, but what were those stories? His- torians have long wondered. Answers have been slow to appear. WNative Americans probably had many more tales, legends, and myths about the Yellowstone country than the few we currently know of, but thanks to Peter Nabokov and Larry Loendorf, we now know more than ever before about some of those early Yellowstone stories. Prior to the emergence of their manuscript American Indians and Yellowstone National Park: A Documentary Overview, his- torians trusted only one Indian legend relating to Yellowstone; that is, they knew of only one that appeared to be genuinely Indian rather than “white” (the Ralph Dixey story discussed below). Moreover, before the Nabokov book appeared, only small, unsatisfying tidbits of Yellowstone information were known to us in general about the Sheepeaters, Shoshones, Crows, Bannocks, Blackfeet, Flat- heads, Kiowas, Arapahoes, Nez Perce, Assinboines, Northern Cheyennes, Gros Ventres, Sioux, and other tribes who inhabited the upper Yellowstone country and its edges at various times prior to 1870. But now, because of that book, we know more than ever before about how these tribes related to Yellowstone. -
The Twin Falls Water Story: More Growth, Less Use
The Twin Falls Water Story: More Growth, Less Use In 1746 among the pages of Poor Richard’s Almanac, Benjamin Franklin noted astutely, “When the well is dry, we know the worth of water.” Those who are intimately involved in city planning can agree it’s best to not wait until the well is dry before understanding the many ways water sustains industry, commerce and the well-being of a population. The City of Twin Falls, Idaho, has made water management a priority for decades. As a result, groundwater consumption has gone down even as their population growth continues at a steady pace. The History of Twin Falls Water When exploring the dozens of waterfalls in the Magic Valley including the sprawling, thundering Shoshone Falls, it’s difficult to imagine the area as a parched desert. “The building of Milner Dam around 1900 is really what brought the City of Twin Falls to life,” said Brian Olmstead, general manager of the Twin Falls Canal Company. “It turned what was once a desert into the rich farmland that it is now.” The implementation of the Milner Dam and the subsequent canal system were an early result of the Carey Act of 1894. Also known as the Federal Desert Land Act, the act promoted cooperative ventures with private companies to establish irrigation systems that would allow large areas of semi-arid federal land to become agriculturally productive. The Milner Dam project provided water to nearly 200,000 acres on the south side of the Snake River. “The initial setup included irrigation shares and ditches that flowed to nearly every lot in town until about the 1960s,” Olmstead said. -

M. Murray, demolished c .1946 OWNER: State of Idaho SIGNIFICANCE: The bridge was built by The Union Bridge Company of Portland, Oregon. It is a cantilever deck truss that rises 550 feet above the height of the River. At the time of construction it was reportedly the "highest" bridge in the world. HISTORIAN: Idaho Department of Transportation, 1977 TRANSMITTED BY: Gary Arabak, 1983 • Twin Falls-Jerome Bridge HAER ID-3 Page 2 PERRINE BRIDGE An unusual obstacle to travel disrupts communication across an otherwise open portion of the Snake river plains of southern Idaho. Immediately below Milner, the river descends into a narrow gorge that reaches a maximum depth of about 600 feet below Shoshone falls. Here the stream bec®mes unnavigable. Worse yet, roads and trails can cross the river at very few convenient spots. Travellers in the valley can come almost to the edge of the gorge without noticing that a large river is anywhere in the area. But aside from a spot above Murtaugh, no fairly easy grade could be constructed down both sides of the canyon to a bridge site for forty miles or more below Milner. -
State Highway Department
Description of WOrk of the State Highway Department in the Counties of the State 1923 -1924 BAKER COUNTY There was less activity in highway constructjon in Baker County dur- ing the biennium just past than in previousyears. However, the main trunk line highway known as the Old Oregon Trailwas completed during this period, and some work was doneon the Baker-Cornucopia and the Baker-Unity Highways. The work on the Baker-Cornucopia Highway involved theconstruction of the grade down the Powder River Canyon, which eliminated the high Sparta summit and materially improved existing communicationbetween the Eagle and Pine Valleys and Baker.However, there still remains a very bad section between Middle Bridge and Love Bridge, and the section between Black Bridge and Richland, through the Dry Gulch country, is impassable to automobile traffic during the spring of theyear. On the Baker-Unity Highway the gradeon both sides of Dooley Moun- tain was completed. Those who were forced to travel the old mountain grade, which was narrow, crooked, and in places reacheda gradient of 22 per cent, will appreciate traveling over thenew highway now open to traffic. The total length of grading completed in Baker County during the past biennium was 18.11 miles, of which 8.95 mileswere surfaced. in addition to this work there were 25.90 miles surveyed. The Baker County bond issue of 1918, amounting to $500,000,was in- sufficient to meet the State in cooperating to complete the state highways through the county, and on November 4, 1924,an additional $500,00G was voted to complete the Baker-Cornucopia and the Baker-Unity High- ways. -

After covering the U.S. Civil War, (many of his photos appear in this earlier series), O'Sullivan joined a number of expeditions organized by the federal government to help document the new frontiers in the American West. The teams were composed of soldiers, scientists, artists, and photographers, and tasked with discovering the best ways to take advantage of the region's untapped natural resources. O'Sullivan brought an amazing eye and work ethic, composing photographs that evoked the vastness of the West. He also documented the Native American population as well as the pioneers who were already altering the landscape. Above all, O'Sullivan captured -- for the first time on film -- the natural beauty of the American West in a way that would later influence Ansel Adams and thousands more photographers to come.

The Hells Canyon Dam Controversy
N 1956, AT THE TENDER AGE OF THIRTY-TWO, Frank Church made a bold bid for the United States Senate. After squeak- I ing out a victory in the hotly contested Idaho Democratic pri- mary, Church faced down incumbent Senator Herman Welker, re- ceiving nearly percent of the vote. One issue that loomed over the campaign was an emerging dis- pute over building dams in the Snake River’s Hells Canyon. While Church and other Democrats supported the construction of a high federal dam in the Idaho gorge, their Republican opponents favored developing the resource through private utility companies. Idaho EVOLUTION voters split on the issue, and so, seeking to avoid a divisive debate, Church downplayed his position during the general election “be- of an cause it was not a winning issue, politically.”1 Senator Frank Church Although Church won the election, he could not escape the is- sue. Indeed, his victory and subsequent assignment to the Senate Committee on Interior and Insular Affairs put him at the center of a growing controversy about damming Hells Canyon. Over the next eighteen years, Church wrestled with balancing Idaho’s demand for economic growth and his own pro-development beliefs with an emerging environmental movement’s demand for preservation of nature—in Idaho and across the nation. As he grappled with these competing interests, Church under- went a significant transformation. While Church often supported development early in his Senate career, he, like few others of his time, began to see the value of wild places and to believe that rivers offered more than power production opportunities and irrigation water.
