Channel width measurements from aerial photographs for selected streamgage sites in Montana The WY-MT WSC conducted a study to develop regression equations for estimating peak-flow frequencies in Montana, using channel-width characteristics. Channel widths were measured from aerial photographs at 517 streamgage sites.
