NASA JOVE research involved hydrologic investigations at Devils Lake, northeastern North Dakota. Landsat MSS satellite imagery was utilized to document changing conditions of the lake system. Devils Lake occupies an enclosed drainage basin with no surface outlet at present. As such, it fluctuates substantially in response to climatic and cultural events. Its surface area, elevation, salinity, and biomass have varied greatly in recent years. With support from the North Dakota Geological Survey, an investigation was undertaken to document these changes during the period 1973-91. The image below represents a typical view of Devils Lake during the late 1980s.
Standard false-color composite for Devils Lake and vicinity. In this composite, active vegetation appears in red and pink colors. The blue color in the western portion of the lake is a reflection of suspended sediment in lake water.
