The presence (or absence) of ice cover on lakes during the winter months affects both regional weather and climate (e.g., thermal moderation and lake-induced snowfall) (Brown and Duguay, 2010; Baijnath-Rodino et al., 2018). However, this is not always the case. It is a priority for CBC to create a website that is accessible to all Canadians including people with visual, hearing, motor and cognitive challenges. 2). Deline, N.W.T., sits on Great Bear Lake north of Yellowknife. Since BU anomalies were relatively small, the spatial pattern of ice cover duration (ICD) anomalies followed closely that of FU anomalies. All areas and trails east of Bear Lake Road have reopened. A., C. R. Duguay, and E. F. LeDrew, 2018: Climatological trends of snowfall over the Laurentian Great Lakes Basin. Rep., 6, 38449. It is ice-covered from November through July and its surface was, in earlier times, used as a highway before a road was built around the lake. Great Bear Lake drains through the Great Bear River into the Mackenzie River. Lake ice is an important component of the cryosphere for several weeks to several months of the year in high-latitude regions. Gaudet helped his friends across and decided to stay behind to warn other travellers who might be coming down the road. ICD for 2017/18 was shorter by up to ~1-4 weeks for Lakes Ladoga and Onega (western Russia) and 2-3 weeks shorter for lakes located in the southernmost part of Finland (ICDs as short as 98 days), northwestern Canada (Great Bear Lake and most of Great Slave and Athabasca lakes) and coastal southwestern Alaska. With a few exceptions, break-up dates were within ±1 week from the 2004-17 mean across the Arctic. The Lake is one of the deeper lakes in the world at 1463 feet, and the water is a pristine lake environment. 130km winter and ice road drive to Indigenous community of Deline on the Great Bear Lake! Pre-glacial valleys formed the bottom of Great Bear Lake. Despite the later FU on Great Bear Lake, when ice did begin to form, the lake froze over faster than the mean time needed to freeze, freezing over completely in 25 days (vs. 30 days mean). Duguay, C., L. Brown, K. -K. Kang, and H. Kheyrollah Pour, 2015a: [The Arctic] Lake ice [in "State of the Climate in 2014"]. And once I crossed I didn't hang around too long.". Ice cover duration anomalies largely mirrored those of freeze-up dates for much of the Arctic. Both Amadjuak and Nettilling lakes show a range of ICD from 11 days shorter to 15 and 18 days longer, respectively. remediation project, AUDIO | The ice roads of Northern Canada are disappearing. There is no better fishing in the world. Duguay, C. R., M. Bernier, Y. Gauthier, and A. Kouraev, 2015b: Lake and river ice, in Remote Sensing of the Cryosphere. "I realized I've got to find a way around it," he said. It's a two-and-a-half hour drive to the nearest community, Tulita. Dinner at B&B Comfortable Hotel accommodations. Hydrol. Brown, L. C., and C. R. Duguay, 2010: The response and role of ice cover in lake-climate interactions. Water flows out of the lake into the Great Bear River, then into the Mackenzie River.Other rivers connected to the lake include the Dease, Camsell and Johnny Hoe. Surdu, C. M., C. R. Duguay, and D. Fernández Prieto, 2016: Evidence of recent changes in the ice regime of high arctic lakes from spaceborne satellite observations. A few lakes with later BU anomalies of the same order of magnitude can be found in northeastern Canada (northern Quebec and Baffin Island, where ice persisted on Amadjuak Lake until 19 August) and Lake Ladoga (Russia), where ice cover persisted until late April (up to 23 days later than usual) and it took 28 days longer than normal for the lake to become ice free. World Meteorological Organization, 315 pp. Cryosphere, 10, 941-960. The department closed the road Saturday night to "let the affected area freeze and allow the department to strengthen the surrounding area with additional flooding.". The pressure will cause the ice to crack, and when the two sides crush together a ridge will form. These dates are compared to mean conditions for the length of the available satellite records, which begin in 2004. ICD on other large lakes, Great Bear and Great Slave lakes, and Lake Taymyr, show variations around the mean with ICD anomalies ranging from -18 to +26 days of ice compared to the mean of all seasons examined, with Great Slave and Great Bear lakes showing negative (shorter ICD) anomalies in 9 of past 14 seasons. Zillow has 99 homes for sale in 84028 matching Bear Lake. Lakes Ladoga and Onega (western Russia) and lakes of smaller size in the southernmost part of Finland froze over in a period spanning mid-January to late February, later than any other region of the Arctic. Lake ice phenology, which encompasses freeze-up (ice-on) and break-up (ice-off) dates, and ice cover duration, is predominantly influenced by air temperature changes and, therefore, is a robust indicator of regional climate trends and variability. J. Despite the later FU on Great Bear Lake, when ice did begin to form, the lake froze over faster than the mean time needed to freeze, freezing over completely in 25 days (vs. 30 days mean). Sci. The question that may be running through your mind is - why of all places Great Bear Lake? All areas and trails east of Bear Lake Road have reopened. 273-306. When Lakes Ladoga and Onega did freeze over, a complete ice cover formed ~2 weeks faster than the mean freeze time for each lake. and surface observations. For example, in the 2012/13 season, ICD followed the BU anomalies closely (Duguay et al., 2013) (Fig. Comments on this story are moderated according to our Submission Guidelines. West of the latter region, and in the Mackenzie Basin (e.g., Great Bear Lake) and the western coast of Alaska, FU occurred later than mean conditions by ~2 weeks, with some small sections of Great Bear Lake exceeding 3 weeks later. It was around 9:30 p.m. As Gaudet got closer, he realized the terrain could be very dangerous — a pressure ridge had formed, leaving standing water and a massive crack longer than the width of the 45-metre road. There is no better fishing in the world. Closed Captioning and Described Video is available for many CBC shows offered on CBC Gem. According to Greg Hanna, a spokesperson with the Department of Infrastructure, the road reopened to light traffic on Thursday afternoon. Prog. Process., 20, 781-801. Ice in some valley lakes in the Scandinavian Mountains range began to form as early as mid-November, which is ~1 month earlier than the mean (Fig. Bull. The Deline settlement is on the lake, near the headwaters of the Bear River. World Meteorological Organization, WMO/TD-No. "So I found a way around it and realized well, it's cracked even beyond that.". Hence, monitoring of lake ice is critical to our skill at regional forecasting (Kheyrollah Pour et al., 2012; Eerola et al., 2014). Analyses of records from ground-based observational networks have provided much of the evidence of long-term trends, variability and regime shifts in lake ice phenology. Satellite remote sensing has assumed a greater role in lake ice observing in recent years due to: 1) a dramatic reduction in ground-based observational recordings globally since the 1980s (IGOS, 2007; Jeffries et al., 2012; Duguay et al., 2015a) and 2) the availability of increasingly longer satellite datasets, particularly from 2000 onward (Duguay et al., 2015b). "He called us and gave us a warning that there's a huge crack in the ice," he said. GCOS 2016 Implementation Plan. Soc., 96, S144-S145. Process., 21, 1576-1586. Hundreds of miles from civilization, Great Bear Lake Lodge is the 4th largest lake in North America and is fished by only 300 lucky anglers each year. The IMS (Helfrich et al., 2007) incorporates a wide variety of satellite imagery (AVHRR, GOES, SSMI, etc.) He and some friends were out for their inaugural rip. He knew what he was looking at because he makes ice roads for a living. "So I slowed down.". Exceptions are some lakes in the Scandinavian Mountains, where ICD was nearly 2 months longer, and Amadjuak and Nettilling lakes (the two largest lakes of Baffin Island). Climatol., 38, 3942-3962. The Lake is one of the deeper lakes in the world at 1463 feet, and the water is a pristine lake environment. Tellus A, 64, 17614, doi: 10.3402/tellusa.v64i0.17614. These lakes have shown positive ICD anomalies for 7 of the last 14 ice seasons, with most of the longer ICD anomalies in the past six seasons. Bear Lake is a beautiful subalpine lake surrounded by pines, aspen groves, ablaze with color in early October, and an easy, accessible 0.5 mile (0.8k) loop trail with essentially no elevation gain. The Great Bear Lake is located in Canada’s Northwest Territories, on the Arctic Circle, at an altitude of 186 meters (or 610 feet). ICD was longer by ~1-2 weeks for most other regions of the Arctic. Inuvik-Aklavik Ice RoadLength: 117 kilometres Average Opening: December 24 Average Closing: April 29 Avg. The most striking FU anomalies are noticeable in southern Finland and western Russia, where lake ice formed ~2-5 weeks later in 2017/18 compared to the mean period.
