  • Tatshenshini River Ten Year Monitoring Report Prepared
    Tatshenshini River Ten Year Monitoring Report Prepared for: Yukon Parks Department of Environment Government of Yukon Whitehorse, Yukon Prepared by: Bruce K. Downie PRP Parks: Research & Planning Whitehorse, Yukon Purpose of the Report The Tatshenshini River was designated as a Canadian Heritage River in 2004. The Canadian Heritage River System requires regular monitoring of the natural, heritage and recreational values underpinning each designation. This report presents the results of the ten year review of the river values and key elements of the management strategies for the Yukon portion of the Tatshenshini watershed. The report also points out which characteristics and qualities of the designated river have been maintained as well as the activities and management actions that have been implemented to ensure the continued integrity of the river’s values. And, finally, the report also highlights issues that require further attention in order to maintain the heritage values of the designation. On the basis of these findings, the report assesses the designation status of the Tatshenshini River within the Canadian Heritage River System. Acknowledgements Thanks are due to the those individuals consulted through this analysis and especially to the dedicated individuals in Yukon and First Nations governments who continue to work towards the protection of the natural and cultural values and the wilderness recreational opportunities of the Tatshenshini River. Appreciation is also extended to Parks Canada and the Canadian Heritage Rivers Board Secretariat for their assistance and financial support of this review.

  • A Family Float Trip Down the Yukon River by John Morton
    Refuge Notebook • Vol. 10, No. 39 • October 17, 2008 A family float trip down the Yukon River by John Morton the Yukon Quest. But it’s equally challenging when young kids are involved and you’re worried about making sure they’re having fun and are SAFE. This is a tall order when they’re inhaling mosquitoes, pad- dling through water as cold as ice with big hydraulics or camping in bear country. Our “wilderness” trip got a rocky start as we passed a sign below Whitehorse that cautioned about treated effluent being discharged into the river. Sev- eral miles below town we ran into a grocery cart stick- ing out of a muddy bar in a bend on the river. As we paddled across the 30-mile long Lake Lebarge, made famous by Robert Service’s poetic celebration of the Cremation of Sam McGee, we saw abundant signs of humans everywhere: tent sites, rusted cans, old cables, and broken glass. But gradually these modern archaeological arti- facts disappear as we get into dining on grayling and wild onions further down the river. Saxifrage, blue- Straight off the water to the telephone, Mika Morton, 11, bells, cinquefoil, wild sweet pea, and fleabane are flow- reconnects with civilization in Eagle after 700 miles on ering everywhere.

Reference collection work done in 1983 was was greatly assisted by Elizabeth Andrews, Steve Rehnke, John Wright, and Dr. Robert Wolfe who made their own collections of regional references available and offered useful suggestions regarding organiza- tion of the bibliography and additional sources. References collected in 1983 sat for over two years awaiting further work and funding, and. for a time it appeared that they would never make it into print. We have Jim Fall to thank for spearheading efforts to resurrect the project in 1986, offering suggestions for updating the collection with new material, reviewing citations and introductory text, and providing the funds for printing. Others contributing additional reference material to the updated collection include Elizaheth Andrews. Susan Georgette, Judy Morris. and Janet Schichnes. Thanks also to Dan Foster, who expertly prepared the maps appearing in the introduction. to Kathy Arndt, who painstakingly edited an early rough draft of the hihliography. and to Margie Yadlosky, who efficiently handled data entry and editing tasks on the data file. Cover artwork was the creation of Tim Sczawinski. Finally. special thanks go to Louis Brown for his programming wizardry which created the microcomputer version of the data base and the indexing routines.

  • Observations of Freeze-Up and Break-Up of the Yukon River At
    JOURNAL OF GLACIOLOGY OBSERVATIONS OF FREEZE-UP AND BREAK-UP OF THE YUKON R I V ERA T BE A V E R, ALASKA* By JOHN R. WILLIAMS (U.S. Geological Survey, Washington, D.C.) ABSTRACT. Observations of faU freeze-up and spring break-up, important to subarctic hydrology and to local economy, were made at the Yukon River town of Beaver, Alaska, September 1949 to June 1950. On October IS, witb river temperature at 0° C., the freezing together of floating ice crystals formed thin icc pans that gradually thickened. Falling river level and increasingly heavy icc concentration choked off all but main channels. On 2S October ice jammed downstream and produced a continuous ice cover and a temporary rise of about I m. at Beaver. After 26 October the river resumed its drop in level until April. Freeze-up appears governed by local channel, current and weather conditions and lacks systen1atic progression either upstream or downstream. Spring thaw beginning in late i>\pril tha\ved sno\\.' cover and weakened river ice. In early ~tay the river began to rise sl()\.vly, but at an increasing rate, untll 13 IVlay when ice ,vas nearly free frorn shore. On 14 :\rIay, after a risc of about 3 m. in 24 hours, the icc broke and moved downstream as the flood crest passed Beaver. Downstream progression of break-up is delayed by local ice jams, the chief cause of disastrous river floods, and is advanced hy early break-up of large tributaries. ZVSAMMENFASSUNG.
