SUMMARY AND CONCLUSIONS
Ice-affected streamflow describes the effects of channel ice on the relationship between stream
stage (water-surface elevation) and flow. Because an ice cover physically blocks the channel and
increases flow resistance, these effects result in lower flows than would be expected from corre-
