Assessing the influence of lake and watershed attributes on snowmelt bypass at thermokarst lakes
TL;DR: In this paper , isotope data were used to estimate the amount of lake water replaced by freshet and to observe how the water sources of lakes changed in response to the freshet.

Modern Eastern Canadian Arctic Lake Water Isotopes Exhibit Latitudinal Patterns in Inflow Seasonality and Minimal Evaporative Enrichment
TL;DR: In this paper , the authors used modern lake water isotopes (δ18O and δ2H) collected between 1994-1997 and 2017-2021 from a transect of sites spanning a Québec-to-Ellesmere Island gradient to evaluate the effects of inflow seasonality and evaporative enrichment on the lake water composition of lake water.

Response of the Porcupine and Old Crow rivers in northern Yukon, Canada, to Holocene climatic change
B. Lauriol,C. R. Duguay,A. Riel +2 more
TL;DR: In this article, a major aggradation took place from 8000 BP to 4000 BP in the Porcupine and Old Crow rivers, northern Yukon, as a consequence of an increase in flow and the result of a perturbation of the permafrost active layer following the early-Holocene climatic warming of northwestern Canada.
