During the last two winters the lower Sagavanirktok River has been affected with extensive aufeis formations. As a result, severe flooding during spring break occurred in 2015. Ongoing research seeks better predictors of flooding in this area. The Ivishak River, a main tributary to the Sagavanirktok River, is ungauged, and aerial field observations taken during winter research on the Sagavanirktok indicated areas of open water along the Ivishak River, potentially a contributing factor in ice formation. Better data from these subwatersheds could offer better indicators on water movement along the Sagavanirktok.
