This report includes the analysis of historical air photos to identify the location and magnitude of changes in channel morphology over time. The area of interest is the 25 km long section of Nanika River between Kidprice and Morice Lakes. This analysis provides a basis for locating sites of interest where ground studies might be undertaken. The report reviews the physical and hydrological setting, and discusses regional land use as relevant background for the historical analyses. Eight images have been compiled at a common scale to document changes in channel conditions over the period since 1946. The most recent imagery is from 2021.
