This week we are exploring urban growth in Ames, Iowa. The red areas are showing areas of vegetation that are primarily agricultural in the larger areas, the neon green areas are short grass and trees, the gray color is urban areas, and blue areas are water.

Timelaspse Video of Ames, Iowa 1984 to 2021 – Summer Landsat Images

As you watch the time lapse video notice several things:

  1. The expansion of Ada Hayden (the large lake in the center right of the image.)
  2. How the agricultural land in the center of the images fills in rapidly with development between 2008 to 2021
  3. The increase in permanent water retention ponds in as the city develops.
  4. Many of the red agricultural parcels along Ioway Creek (the left river) become smaller and more developed through the time series.

Today’s time lapse video is highlighting the damming of Brushy Creek and the creation of 690-acre Brushy Creek Lake, Iowa’s deepest artificial lake.

Watch the dam development begin around 1994 and then the lake begin to fill around 1998. The Brushy Creek State Recreation Area is a 6500-acre park located in north central Iowa.
