Tolton Dam, located in Villisca, Iowa, is a privately-owned structure designed by Snyder & Associates for the primary purpose of recreation. Completed in 2020, this earth dam stands at a height of 30 feet and spans a length of 1360 feet, with a storage capacity of 74 acre-feet. The dam is situated on an unnamed tributary to Seven Mile Creek, within a drainage area of 0.13 square miles.

With a low hazard potential and a moderate risk assessment rating, Tolton Dam is regulated by the Iowa Department of Natural Resources and undergoes state permitting, inspection, and enforcement. The dam features an uncontrolled spillway with a width of 10 feet, and has not been rated for its condition assessment. Despite its recent completion, the dam has already become a focal point for water resource and climate enthusiasts seeking recreational opportunities in the area.
