AbstractStewart Lakes are dammed by neoglacial moraines in a through-valley between Gibbs and Sam Ford fiords in northeastern Baffin Island. Maximum water depth on the basis of spot soundings is 108 m. Glaciers are retreating at rates between 19 and 34 m/a, and the lake level has lowered from 69 m above sea level to 55 m as a result of ice retreat and downcutting of the moraines. On 13 September 1983, suspended sediment concentrations in Stewart Lakes varied from 66 to 109 mg/L. In Refuge Harbour (Gibbs Fiord) the concentration in overflowing fresh water was 135 mg/L. These values are significantly higher than those measured in most other ice-proximal lakes and fiords.
