The survey was initiated to assess angling pressure, angling effort, catch rate and angler satisfaction. These data were compared with data collected from previous angling surveys in the UOM drainage between 1988 and 1992 to assist resource managers in monitoring the status of the cutthroat trout fishery. A total of 2,941 anglers fished a total of 8,468 h in the UOM drainage and reported a combined catch of 9,560 cutthroat trout, 93 rainbow trout, 84 bull trout and 60 mountain whitefish. Of the 9,560 cutthroat, 2,531 (26%) were legal‐size (i.e., total length ≥ 30 cm), two‐thirds of these were captured in the Livingstone River. The catch‐per‐ unit‐effort (CPUE) for cutthroat trout across the entire study area averaged 1.13 fish/h. There was no clear temporal pattern in CPUE. However, CPUE on the Livingstone River was higher in 2004 than in 1992, but the reverse pattern occurred on Dutch Creek over the same period. In 2004, angling pressure was lowest on Dutch Creek and Racehorse Creek and highest on the Livingstone River. Overall, angling pressure was higher in 2004 than in previous surveys in 1988 and 1992. In addition, angling pressure shifted from the Upper Oldman River during the 1988 to 1992 surveys to the Livingstone River in 2004. The shift in popularity toward the Livingstone River was likely due to the increased size and number of cutthroat trout in this system, presumably related to the implementation of a catch‐and‐release regulation on the Livingstone River in 1995. In contrast to the Livingstone River, catch rates decreased on the Upper Oldman River and Dutch Creek from 1992 to 2004, and anglers captured fewer and smaller cutthroat trout in these rivers compared to the Livingstone River. Despite the overall increase in fishing pressure, the majority of anglers felt that the size and number of cutthroat trout caught in the drainage did not change between 1992 and 2004. Of the 2,941 anglers interviewed during the study, the majority (95%) were residents of Alberta, 3% were from out of province and 2% were from the United States. Fly‐fishing was the most common angling method and provided the greatest overall CPUE. ii ACKNOWLEDGEMENTS A number of individuals and organizations contributed to the angler survey. We thank Nathan Shaw, angler survey technician, for assisting with the angler survey and Mike Jokinen, Trevor Council and Daryl Wig for assisting with survey preparations. Alberta Public Lands and Forest Division, Gap Base, allowed us to establish a field camp at the fire base and also provided access to facilities. Devon Canada Corporation funded a portion of the angler survey.

ACKNOWLEDGEMENTS We thank Frank Bishop and Della Clish of the Alberta Fish and Wildlife Division for important suggestions concerning sportfishing in southern Alberta and technical assistance. We also welcome the interest of Trout Unlimited in supporting the study. We gratefully acknowledge the Alberta Fish and Wildlife Division and the Fisheries Enhancement Fund for funding this project. PREFACE This is the third report resulting from the study: "A Socioeconomic Evaluation of Sportsfishing Activity in Southern Alberta." The first report dealt with general results from the survey, while the second focused specifically on the impacts of the Oldman River Dam on recreational fishing in the Crowsnest area. This, the third report, examines the economics of fishing in a more regional framework, and investigates a number of behavioural assumptions in deriving non-market values associated with fishing in the area. A number of resource management scenarios are examined in this study. These were chosen with no particular knowledge of actual or contemplated management actions. However, the treatment of these scenarios illustrate how a vast number of management alternatives which result in changes in environmental or recreation quality could be examined in an economic context.

  • Gold Creek Cutthroats, Condemned by Coal? Below You Will Find the Second Revision to a Story Which Began in July 2015 and Continues to This Day
    Gold Creek Cutthroats, Condemned by Coal? Below you will find the second revision to a story which began in July 2015 and continues to this day. Since its writing, the Alberta Energy Regulator has rendered it's decision: (Link failed to load, see instructions below) The AER's decision is wildly inconsistent with my independent investigation of the incident and contrary to the findings I discussed with federal investigators looking into the file. While it will take a significant amount of work and time to correlate the inconsistencies, a few stick out like sore thumbs. I believe it in the public interest to be aware of this incident prior to the December 8, 2017 closing of submissions regarding the mine's operational permit, and as such, I'll provide what I can at this time. Notable Issues and Inconsistencies: -The Date of the Thunderstorm/s: The AER contends the storm occurred on July 17 and goes on to reference Alberta Environment and Parks data in its report claiming, "Alberta Environment stream-flow data for Gold Creek (north of the release) confirms that there was a large spike in the measured flow in Gold Creek. My investigation informs a major thunderstorm occurred on July 11 and another smaller storm in the area on July 16. Alberta Environment and Parks data confirms my findings, as pictured in the post, not the AER's. -Inability of the Regulator's Investigators to Identify Coal Deposits: The AER decision states, "AER staff did check the Gold Creek Bridge at Hwy 3 near Frank, Alberta and could not identify any coal deposits at that location" A picture's worth a thousand words; clearly the posted picture shows coal fines deposited at the Highway Three Bridge in Frank.

  • Selenium Central on the Crown of the Continent
    Selenium Central on the Crown of the Continent Teck Resources has stepped up to the selenium plate in a robust way committing over one billion dollars to the mitigation of impacts from this potentially toxic metal in British Columbia's Elk River watershed. Meanwhile in Alberta, the Alberta Energy Regulator continues to deny not only historic impacts, but has frankly refused to investigate new release events. One investigation the regulator did attend to as a result of my personal efforts prior to the creation of the, Crowsnest Journal was the release of coal and other substances from the east flank of Grassy Mountain in 2015. I discussed the obvious disparity between the AER's report and my investigation with Riversdale Resources/Benga Mining in late 2017; later that week, the firm's lead environmental contact left the firm. RR/BM has refused further comment on the matter citing privacy concerns. The Fernie Free Press reports on the new commitments by Teck, "Teck’s water treatment facility on track for 2020 completion": https://www.thefreepress.ca/…/tecks-water-treatment-facili…/ Previous reports from the CNJ on the pictured release events are found here, "Ineffective Oversight from the Alberta Energy Regulator": https://www.facebook.com/thecrowsnestjournal/posts/1453149848153310?__tn__=K-R "Selenium, What's the Big Deal?" a collection of articles posted to the CNJ provides background and understanding on the issue: https://www.facebook.com/thecrowsnestjournal/posts/1158244654310499 The headwaters of the Oldman River are the water tower for southern Alberta and points beyond.

Heavy rainfall commenced on June 19th and continued for three days. When the event was over, more than 200 mm and as much as 350 mm of precipitation fell over the Front Ranges of the Canadian Rocky Mountains. Tributaries to the Bow River including the Ghost, Kananaskis, Elbow, Sheep, Highwood, and many of their tributaries all reached flood levels. The storm had a large spatial extent causing flooding to the north and south in the Red Deer and Oldman Basins, and also to the west in the Elk River in British Columbia. Convergence of the nearly synchronous floodwaters downstream in the Saskatchewan River system caused record high releases from Lake Diefenbaker through Gardiner Dam. Dam releases in Alberta and Saskatchewan attenuated the downstream flood peak such that only moderate flooding occurred in Saskatchewan and Manitoba. More than a dozen municipalities declared local states of emergency; numerous communities were placed under evacuation order in Alberta and Saskatchewan. More than 100,000 people needed to evacuate their homes, and five people died.

  • Water Quality in the South SK River Basin
    Water Quality in the South SK River Basin I AN INTRODUCTION TO THE SOUTH SASKATCHEWAN RIVER BASIN I.1 The Saskatchewan River Basin The South Saskatchewan River joins the North Saskatchewan River to form one of the largest river systems in western Canada, the Saskatchewan River System, which flows from the headwater regions along the Rocky Mountains of south-west Alberta and across the prairie provinces of Canada (Alberta, Saskatchewan, and Manitoba). The Prairie physiographic region is characterized by rich soils, thick glacial drift and extensive aquifer systems, and a consistent topography of broad rolling hills and low gradients which create isolated surface wetlands. In contrast, the headwater region of the Saskatchewan River (the Western Cordillera physiographic region) is dominated by thin mineral soils and steep topography, with highly connected surface drainage systems and intermittent groundwater contributions to surface water systems. As a result, the Saskatchewan River transforms gradually in its course across the provinces: from its oxygen-rich, fast flowing and highly turbid tributaries in Alberta to a meandering, nutrient-rich and biologically diverse prairie river in Saskatchewan. There are approximately 3 million people who live and work in the Saskatchewan River Basin and countless industries which operate in the basin as well, including pulp and paper mills, forestry, oil and gas extraction, mining (coal, potash, gravel, etc.), and agriculture. As the fourth longest river system in North America, the South Saskatchewan River Basin covers an incredibly large area, draining a surface of approximately 405 860 km² (Partners FOR the Saskatchewan River Basin, 2009). Most of the water that flows in the Saskatchewan River originates in the Rocky Mountains of the Western Cordillera, although some recharge occurs in the prairie regions of Alberta and Saskatchewan through year-round groundwater contributions, spring snow melt in March or April, and summer rainfall in May and early July (J.W.
