East Lake Dam, located in Clarke County, Iowa, serves as a crucial water supply source for the region. Built in 1915 by the USDA NRCS, this earth dam stands at a height of 41 feet and spans 795 feet in length. With a storage capacity of 257 acre-feet and a surface area of 13 acres, the dam plays a vital role in regulating water levels in the White Breast Creek watershed. Despite being uncontrolled, the dam's spillway width of 3 feet helps manage water flow during periods of excess precipitation.

Managed by the Iowa DNR, East Lake Dam is subject to regular inspections and enforcement measures to ensure its structural integrity and public safety. The dam has been assessed as being in satisfactory condition, with a significant hazard potential due to its location and size. With a moderate risk assessment score of 3, the dam has measures in place to mitigate potential risks and respond effectively in emergency situations. As a key component of the local water infrastructure, East Lake Dam showcases the importance of sustainable water resource management in the face of climate variability and changing hydrological patterns.
