Stable isotopes of hydrogen (δ2H) and oxygen (δ18O) provide important quantitative measures of lake hydrology and water balance, particularly in lakes where monitoring of fluxes is incomplete. However, little is known of the relative effects of seasonal variation in water isotopes on estimates of lake hydrology, particularly over decadal scales. To address this gap, we measured water isotopes bi-weekly May-September during 2003–2016 in seven riverine lakes within the 52,000 km2 Qu’Appelle River drainage basin of the Canadian Prairies. Analyses revealed that within-year variation in δ18O values routinely exceeded that among years, reflecting rapid changes in water source, particularly in lakes with water residence times |
