Abstract The Great Salt Lake, located in the state of Utah, is the largest salt water lake in the West and the eighth largest terminal lake in the world. The lake is a home for millions of native birds, shorebirds, and waterfowl, including the largest staging population of Wilson’s phalarope in the world. Since 1847, there has been a constant decline in its area. Lake Powell is a lake near the Colorado River in the United States and serves as a major vacation destination for approximate 2 million people annually. However, because of successive droughts and insatiable requirement of water for human and agriculture, Lake Powell has fallen way below in terms of water, depth, and surface area. This study focused on the temporal changes of these two lakes using the multi-temporal Landsat images using Prewitt edge detection and the comparison of the result with other edge detection techniques. The results thus obtained reflect the constant decline in Lake Powell and the Great Salt Lake in terms of surface area in the period 1984–2018 and 1987–2018, respectively.

of mature rivers. There are many lakes, in different parts of the globe, which were formed because of improper drainage systems. None of the lakes are permanent, as they will slowly get filled up with sediments or tip over the basin containing them. Many lakes are artificial in nature and have been constructed for serving the industrial or agricultural needs, or for hydro-electric power generation and domestic water supply, or for exquisite, recreational purposes, or some other activities. Over the years, surface water bodies like lakes, ponds, reservoirs, etc. have been treated as a community resource. They were being nurtured, protected, conserved and managed by the major percentage of the local community without any code of conduct or rule. In turn, these water bodies have been catering the local human and livestock populations. In the modern times, after the introduction of water supply for the public and ground water usage through the hand pumps and wells, a dramatic shift in the attitude of the people towards these water bodies has been witnessed. Both the governments as well as the locals have b
