In the Wasatch front surface water plays a large role in sustaining the population in the area. As population increases in the rapidly growing area some changes in the availability of surface water is expected. To quantify how much change has happened in the surface water in this area, Landsat imagery from 1985 to 2019 was processed using ERDAS Imagine and ArcGIS. Bands 4, 5 and 7 were stacked on all the years in the study and clipped to the watershed in which Utah Valley is located. Classifications were made to group similar pixels in an image, surface water being one of them. Change was calculated by comparing the water classifications against each other in the years 1985 to 2019.
