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. Necessary for plants ● Silica, mg/L ● 16.5 ● Indicates water hardness ● Manganese, ug/L Radiation ● 2.95 ● Maximum Contaminant Level (MCL) = 15 pCi/L, MCL goal ● Alpha particles, pCi/L ● 0.03 (MCLG) = 0 pCi/L. Alpha particles are a ionized radiation ● Radium-226, pCi/L form of Polonium-210 decay which is carcinogenic at 0.1 pCi/L so Po-210 should be tested ● MCL = 3, MCLG = 0 Goal 1: Keep Water Quality at Fishable Standards Environment ● Consistent water monitoring ○ Heavy metals and Po-210 ● Decrease water hardness ○ Add water softener Economy ● Increase water nutrients ○ Implement riparian buffer zone ● Control mine runoff Equity ○ Safely close abandoned gold mines ● Improve bulk fuel safety, replace broken valves and leaking pipes/tanks ● Implement renewable energy sources ○ Wind, solar, and hydropower Problem 2: Salmon Industry ● Important food source for residents ● Economic impact ● Catch records low ● Problems for chum: ○ Low water temperature ○ Low food abundance https://www.fws.gov/fisheries/freshwater-fish-of- ○ Low water quality america/chum_salmon.html Goal 2: Salmon Hatchery Environment ● First hatchery implemented in 1970 huge success ● Majority of salmon harvest and release in southeast Economy ● A more convenient way to spawn ● Recirculating system to preserve heat ○ Produce 1 million eggs with only 10 liters of water/minute Equity Problem 3: Increased Freshwater Input ● Result of ○ Glacial melting (and overall climate change) ○ Increased development ● Negatively affects ○ Summer and fall Chum Salmon populations (lowering of water temperatures) ○ Plankton communities ○ Downstream estuarine ecosystems at mouth of Yukon River (decrease in salinity) ○ Natural nutrient cycling processes Goal 3: field and computational-based scientists to work on water temperature and salinity, glacial mass balance, and policy making Environment Economy Equity Concluding Recommendations ● Implement more complete and consistent water sampling and monitoring (Immediate) ○ Including for heavy metals and Po-210 radiation ○ Water Temp. and salinity ● Treat drinking water with water softener (Immediate) ● Improve safety of bulk oil facilities (By 2025) ○ Training for workers at the oil units ○ Replace leaking pipes, valves, and tanks ● Salmon hatchery implementation (2022-2024) ● Implement riparian buffer zone (2022-2030) ● Renewable energy sources (Gradual 15 year shift) ○ Wind, solar, and hydropower References APEC Water.
