Chandalar River United Management (CHUM) Chandalar River United Management (CHUM) Dan Clark, Jeff Chang, Mary Kate Dinneen, Tyler Sharretts, Nicole Steplewski Background ● Tributary of the Yukon River ○ 567 miles long ○ 15,407 square mile drainage area ● Flows through and connects to the Yukon in the Yukon Flats Wildlife Refuge ● Contains several fish species ○ Summer and Fall Salmon Runs ○ Humpback, Broad, and Round Whitefish ○ Arctic Grayling, Northern Pike, Chinook ● The watershed contains two villages ○ Venetie ○ Arctic Village GIS Chandalar River Watershed Climate GIS Map Chandalar River Anthropogenic Impacts Venetie History ● Its name came from the French term “Gens de Large,” meaning “nomadic people,” used to name the Kutchin Indians that lived along this stream. Early USGS field notes spelled it “Chand-da-larg,” creating Chandalar. ● The river has recently been renamed in 2015 to its traditional Gwich’in name, the Teedriinjik River, meaning “Luminous River” or “Shining River.” ● In 1905, miners set up camps in the area due to the gold rush, but they mostly left by 1910. ● The population is mostly descendants of the Neets’ai Gwich’in native people. They continue to practice subsistence activities involving caribou and fish for their daily lives and culture. Current Governance: YRITWC YRITWC Policies Current Governance: Government of Yukon, Canada Yukon, Canada Policies Mission Statement CHUM’s mission is to guarantee that the river remains sustainably fishable until the year 2035 and beyond in order to protect the native fish species that occupy the river, which many communities within the river basin are dependent on, and fuel the local sportfishing industry. We also aim to improve overall water quality and mitigate freshwater input. Problem 1: Water Quality ● Heavy metal persistence (Pb, etc.) ○ Gold and Lead/Zinc mining ○ Inconsistent and incomplete testing ● Continuously leaking bulk fuel tanks ○ Venetie - fails many basic requirements ● High sediment loads ● Hard water ● High freshwater input ● Low nutrients Water Quality Indicator Average Value Analysis Specific Conductance, uS/cm @ 25C 218.94 (Range: 147-308) Relatively normal but a bit high for salmon, indicator of possible pollution ● pH ● 7.9 ● Ideal range for most fish is 6.5-8.5 so this is ideal ● Alkalinity, mg/L CaCO3 ● 105.4 ● High buffer capacity, higher end indicates water hardness Total dissolved solids, mg/L 151 Indicates hard water ● Hardness, Ca, Mg, mg/L CaCO3 ● 120 ● Hard water range, high chemical weathering of rocks ● Ca 2+ dissolved, mg/L ● 39 ● 25> suggests high suitability for mollusks Nutrients ● 0.68 Low nutrients due to high freshwater input ● Nitrate, mg/L as N ● 0 ● Phosphate has been used up and is a limiting factor in ● Orthophosphate, mg/L as PO4 ● 0.65 biolife ● Potassium, mg/L Minerals ● 2.8 ● Significantly low, usually 5-25 mg/L.

  • Environmental and Cultural Overview of the Yukon Flats Region Prepared By: Kevin Bailey, USFWS Archaeologist Date: 2/12/2015 In
    Environmental and Cultural Overview of the Yukon Flats Region Prepared by: Kevin Bailey, USFWS Archaeologist Date: 2/12/2015 Introduction With a substantial population of Native people residing in their traditional homeland and living a modern traditional lifestyle, the Yukon Flats Refuge and all of the Alaskan Interior is a dynamic and living cultural landscape. The land, people, and wildlife form a tight, interrelated web of relationships extending thousands of years into the past. Natural features and human created “sites” form a landscape of meaning to the modern residents. The places and their meanings are highly relevant to modern residents, not just for people and culture but for the land. To many Gwich’in people culture is not distinct from their homeland. Although only minimally discussed in this overview, this dynamic living cultural landscape should be considered and discussed when writing about this area. Environmental Setting Containing the largest interior basin in Alaska, the Yukon Flats Refuge encompasses over 11 million acres of land in east central Alaska. Extending roughly 220 miles east-west along the Arctic Circle, the refuge lies between the Brooks Range to the north, and the White-Crazy Mountains to the south. The pipeline corridor runs along the refuge’s western boundary while the eastern boundary extends within 30 miles of the Canadian border. The Yukon River bisects the refuge, creating the dominant terrain. As many as 40,000 lakes, ponds, and streams may occur on the refuge, most concentrated in the flood plain along the Yukon and other rivers. Upland terrain, where lakes are less abundant, is the source of important drainage systems.

It is 567 miles, and joins the Yukon River at the Yukon’s 982nd mile (U.S Fish and Wildlife Service, 1990). It is formed by the confluence of the North Fork Chandalar River and Middle Fork Chandalar River, which combine to form the Main Stem, The largest Fork is the East Fork, which joins the Main Stem upstream of Venetie (U.S Fish and Wildlife Service, n.d.). As the East Fork meets the Main Stem, the river flows through the Yukon Flats Wildlife Refuge. The river is home to several species of fish, much of which are depended upon by the local population, and which also fuel the local sportfishing industry. Arctic Grayling, Northern Pike and several species of whitefish; Humpback, Broad and Round, are abundant. The whitefish have been observed using connected streams to spawn, and additionally utilize connected lakes for both feedings and overwintering.

  • Patterns of Fish and Wildlife Use for Subsistence in Fort Yukon, Alaska
    PATTERNS OF FISH AND WILDLIFE USE FOR SUBSISTENCE IN FORT YUKON, ALASKA Valerie A. Sumida and David B. Andersen Technical Paper No. 179 Alaska Department of Fish and Game Division of Subsistence Fairbanks, Alaska December l!WO This research was partially supported by ANILCA Federal Aid Funds, administered through the U.S. Fish and Wildlife Service, Anchorage, Alaska, SG-1-7 and SG-1-8. ABSTRACT Fort Yukon, located along the Yukon River in northeastern interior Alaska, is the largest Athabaskan community in the state with an estimated population of 584 residents comprising 212 households in 1987. This study was undertaken to gather quantitative information on subsistence harvest and use of ftih and wildlife resources by Fort Yukon residents. These data, along with updated land use maps and socioeconomic information, were intended to complement a previous description of Fort Yukon subsistence activities published by the Division of Subsistence in 1983. Data collection took place from August 1987 through October 1988 using a household survey administered to a stratified sample of 72 (34 percent) of Fort Yukon households. Serving as the hub for administration and services in the Yukon Flats region and surrounding communities, 65 percent of the wage employment opportunities in Fort Yukon were in the federal, state, and local government sector. Jobs were predominantly seasonal or part-time in nature with only about 25 percent of jobs offering permanent, full-time employment. The median annual household income from all sources in 1987 was estimated to be $17,856. Among all households, the Alaska permanent fund dividend was the largest single source of non-wage income, averaging almost $1,529 per household.

  • Appendix I. Wild and Scenic River Review
    Appendix I Wild and Scenic River Review Appendix I: Wild and Scenic River Review I. Wild and Scenic River Review The Arctic National Wildlife Refuge (Arctic Refuge, Refuge) is completing a wild and scenic river review as part of this revision of the Comprehensive Conservation Plan (Plan, Revised Plan). The Wild and Scenic Rivers Act requires that such a study be completed whenever Federal agencies revise their land use plans. The process consists of several steps, including inventory, eligibility evaluation, suitability study, and potential congressional designation. The first two steps are to inventory the Refuge’s rivers, and then determine which of the rivers meet the criteria for eligibility (i.e., that they are free-flowing and contain one or more outstanding river-related values (as defined in the Wild and Scenic Rivers Act). The third step, the suitability study, determines whether each eligible river or river segment would be a worthy addition to the National Wild and Scenic Rivers System. The findings of the eligibility and suitability studies are presented in this appendix, and preliminary suitability determinations are included for each river evaluated for suitability. The final decision on the suitability of a given river segment will be made in the record of decision for the Revised Plan.
