December 2014 Volume 1, Issue 1 The Flow News from the Peace-Athabasca Delta Ecological Monitoring Program Welcome to the PADEMP newsletter Welcome to the first edition of “The Flow” - the newsletter of the PeaceAthabasca Delta Ecological Monitoring Program (PADEMP). The PeaceAthabasca Delta (PAD), located in north-eastern Alberta where the Peace and Athabasca Rivers meet at the western end of Lake Athabasca, is one of the world's largest freshwater deltas. It is a Ramsar Wetland of International Importance, and is one of the features that contribute to Wood Buffalo National Park's status as a World Heritage Site (80% of the delta lies within WBNP). PADEMP was established by Parks Canada in 2008 to monitor the cumulative effects of regional development and climate change on the health of the PAD. Members include Aboriginal, federal, provincial, and territorial governments and environmental nongovernment organizations. PADEMP’s mandate is to develop and implement a long-term ecological monitoring program that will evaluate and communicate the state of the delta. Both Western Science and Traditional Ecological Knowledge are being used in program development In this issue: and implementation, and in the interpretation of monitoring results. Every few months we hope to bring you stories about the delta, profiles of the people that make the delta home, results from those that are studying the area, and other news and views related to the delta. This first issue is dedicated to the memory of Willie Courtoreille, a Mikisew Cree First Nation elder who was a strong, articulate and respectful advocate for the traditional knowledge of his people and the protection of the Peace-Athabasca Delta. Welcome to the PADEMP newsletter Spring flooding replenishes wetlands Muskrat update News and Views Willie Courtoreille—a lifelong defender of the Peace-Athabasca Delta On December 10, 2013 the Mikisew Cree First Nation (MCFN) lost a long-time Councillor, PADEMP supporter and beloved Elder, Willie Courtoreille. Willie was born on February 16, 1940 and grew up in the bush surrounded by the love of his parents, John James and Veronica, as well as his step –parent Therese and his many brothers and sisters. Willie Courtoreille in the 1970s. Willie was hired by Parks Canada at 16 to work on the fire crew and soon moved up to act as a fire crew instructor, and then as part of the fire management team. He was ultimately hired on year round to do park patrols and main- tenance. During the winter months Willie was an active trapper. Willie began politics as a MCFN Councillor in 2007 and spent 7 years on council. He joined PADEMP in 2008. He was a fountain of wisdom about the land, water, animals and fish in the traditional territories of the Mikisew Cree and fought hard to ensure the wisdom and values of his people were protected and preserved. Page 2 2014 spring flood replenishes Delta wetlands For the first time since 1997, spring ice jams on the Peace and Athabasca Rivers created a major spring flood in the delta . This was a very exciting event because the health of the delta depends on periodic spring flood events (every 6-9 years, according to Traditional Knowledge), and this hadn’t happened for a very long-time due to the effect of flow regulation and climate change (see News and Views, p.4). The ice jam on the Peace River established itself in early May and lasted for over a week. The downstream end was anchored on the Slave River at 30th baseline, and the head of the jam extended upstream as far as Burnt Thumb. Water levels breached the banks of the Peace River in many areas, creating overland flooding. Flows reversed on most Ice jams on the Peace and Slave Rivers backed up water and caused extensive flooding in the delta for the first time since 1997. channels south of the Peace (Sweetgrass River, Claire River, Baril River, Quatre Fourches, Revillon Coupé and Rivière des Rochers), carrying flood waters into adjacent wetlands and further into Lake Claire, and Mamawi and Baril Lakes. There was notable flooding in the area around Egg Lake, Jerry’s Lake, and Pushup Lake, resulting from a small ice jam that formed on the Quatre Fourches River. As water levels in the larger lakes rose, wetlands on the margins of the lakes flooded too. At the same time, ice jams and high water along the Athabasca River flooded large areas south of Lake Mamawi, between the Embarras and Egg Lake, dry for many years, received water in the 2014.spring flood. Athabasca Rivers, and along the delta reach of the Athabasca River and its channels. Flows from the Athabasca River contributed to higher lake levels as well, with high Peace River water levels preventing any drainage to the north. Parks Canada, Environment Canada, Natural Resources Canada and BC Hydro conducted activities to document the flood. These included aerial and groundbased observations of flood extent and water levels, water sampling to trace flood water source, and remote sensing. In the near future, this information will be brought together to further assess the flood’s extent and fully describe the conditions that created it. Ongoing monitoring using both western science and Traditional Knowledge will help us understand the impact of this flood on delta ecology. Page 3 Volume 1, Issue 1 Muskrat numbers in the PAD rising after spring flood In December 2014, participants in the annual PADEMP muskrat count found that muskrat numbers may be on the rise! We counted an average of 30 houses per basin (ten times last winter’s average of three houses per basin!) across 24 lakes in the PAD. How is the relative abundance of muskrat changing over time? Is there a difference in muskrat abundance between basins receiving water from the Athabasca River and those that do not? How long does it take muskrats to re-establish after floods? Is there a difference in water quality between productive and unproductive basins? How are we doing it? Ground Survey: Park staff, trappers and David Campbell, left, Archie Antoine and Ross Campbell pose with a huge rat house in the delta. land-users began by identifying basins where trappers used to find lots of muskrat. Crews count active houses and pushups at the same Parks Canada and community observers fly over the same muskrat basins. They count houses and pushups from air in late winter to 120 muskrat houses per basin Muskrat can tell us about the health of the delta ecosystem. They play a key cultural and ecological role, and are sensitive to changing water levels. In recent years, Traditional Knowledge Holders pointed out that many lakes where they used to trap muskrat were empty. In 2012, community members, trappers, and Knowledge Holders from Fort Chipewyan identified questions they have been working with PADEMP to answer: 100 80 60 Dec. 2014 40 20 0 1972 1977 1982 1987 1992 1997 2002 2007 2012 Year Numbers of muskrat houses in the PAD fell sharply from 1977-1998 but can rise after years with big floods such as 1972, 1974, 1997 and 2014. basins twice every year: in early and late winter. This gives us an idea of how many muskrats are able to survive the winter. While we’re at the basins, we measure depth of snow, ice, and water, and vegetation composition of houses and pushups. Aerial Survey: Every year, estimate changes in muskrat numbers over time. Findings so far... On December 1-4, 2014, we counted 715 muskrat houses and 575 pushups at 24 lakes in the PAD. Lakes with muskrat have more water on average than those without. This confirms that water levels are important in determining which basins can support muskrat in the PAD. What’s next? 1) Our muskrat study is in its fourth year, but we know from elders that muskrat numbers used to be much higher. Can we translate this knowledge into a traditional baseline for muskrat numbers in the PAD? 2) In spring of 2014, water levels were higher in the PAD than they have been since the floods of 1997. Is this what caused muskrat numbers to increase, and will numbers stay high? 3) In December 2014, we had high school students from Fort Chipewyan involved in the muskrat study. By involving youth in the surveys, we hope to help connect youth and elders on the land. News and Views Mercury in Gull and Tern Eggs A report published in 2013 identified a trend toward increasing levels of mercury in gull and tern eggs collected from Mamawi Lake and Lake Athabasca. This suggests that mercury levels could be increasing in the delta area. Additional research is being undertaken to better understand the source, levels and trends of mercury in the area.

Gull and Tern Egg Advisory In May 2014, Alberta Health issued an advisory regarding the consumption of gull and tern eggs from Lake Mamawi and Lake Athabasca. The advisory was based on results of the study above about mercury levels in these eggs. The advisory identifies weekly consumption limits for children, pregnant women and adults, but if fish are regularly consumed from these lakes then no gull or tern eggs should be eaten by anybody. The advisory can be found at: mywildalberta.com/Hunting/ SafetyProcedures/ GullAndTernEggConsumptionAdvisory.aspx Is Oil Sands Development Increasing Contaminant Levels in the Lower Athabasca Region? Scientists studied sediment cores taken from 5 lakes near the main oil sands development area and from one lake further away. They found that contaminant (PAH) levels in these lakes have been rising since the 1960s, and concluded that the development and refining of oil sands plays a role in this trend. They also determined that climate change is driving significant ecological change in these lakes, and that the combination of the PAH trends with predicted climate change effects is creating “great potential for Athabasca oil sands ecosystems to experience marked changes in their function and ecological organization”.

Sciences online. 6pp. Delta Drying: what’s the cause - flow regulation or climate? Dr. Spyros Beltaos is one of Canada’s leading experts on river ice processes. His recent report examines a longstanding question: is the delta drying trend observed since construction of the W.A. C. Bennett Dam due to flow regulation by the dam or due to climate? He concludes that both play a big role, but that Peace River flow regulation by the Bennett Dam has the larger effect.
