Kentucky Lake is the largest reservoir by surface area in the US east of the Mississippi River. A long-term monitoring program has been in place since 1988 at Murray State University’s Hancock Biological Station on the Lake. In Situ data that measures various aspects of the physical, biological, and hydrological properties of the Lake have been collected at over 20 sites in the Lake, on the dates that coincide with the flyby of Landsat satellites. In this study, the long-term pattern of in situ data collection on temperature, chlorophyll and turbidity is explored. Cloud-free Analysis-Ready Landsat-5 and Landsat-8 imagery is collected for 1988-1993 and 2013-2018, and studied for its capability of predicting chlorophyll and turbidity measurements. It also compares Landsat-5 and Landsat-8 imagery for their ability of monitoring chlorophyll and turbidity in Kentucky Lake.
