Change Over Time – Flooding on the Landscape (NW Iowa)
Use sliders to compare images.
Today’s image shows an area in northwest Iowa between Spencer (Clay County) and Emmetsburg (Palo Alto County). The two images on the left are showing water levels in 1990 (typical year) and 2022 (recovering from a drought) compared to 1993 (heavy flooding) and 2008 (flooding). Notice the swollen streambanks and flooding along water bodies in the right images.
This year we are celebrating 50 years of the Landsat earth observing satellite mission. Landsat data helps us observe changes in our communities and environment over time.
