More than half a billion people live near lakes that freeze over in the winter. However, lakes are rapidly losing winter ice cover in response to warming, and the rate of loss has accelerated over the past 25 years. Hampton et al. reviewed the state of seasonal ice cover on lakes and discuss some of the consequences of its disappearance. Ice loss will affect culture, economy, water quality, fisheries, and biodiversity, as well as weather and climate. —Jesse Smith

Concentrations of road deicing salt are increasing in many inland waters. High salt concentrations can negatively impact aquatic organisms and ecosystems. Few frameworks exist for predicting how high road salt concentrations might become in lakes. We present a simple, generalizable model that predicts equilibrium road salt concentrations in lakes as a function of salt application rate, road density, and runoff.
