Lansink Dam, located in Ida Grove, Iowa, is a privately owned structure designed by NRCS for fire protection, stock, or small fish pond purposes. Completed in 2008, this earth dam stands at a height of 21 feet and spans 395 feet in length, with a storage capacity of 53 acre-feet. Situated on TR- Hoskins Creek, the dam serves as a crucial resource for water management in the area, with a surface area of 4.9 acres and a drainage area of 0.3 square miles.

Despite being classified as low hazard potential with a moderate risk assessment, Lansink Dam has not been rated for its condition. However, it is equipped with an uncontrolled spillway and has a spillway width of 2 feet. While the dam has not been modified in recent years and lacks certain emergency preparedness measures like an EAP and updated inundation maps, it remains a significant asset for the community in terms of water resource management. With its strategic location and purposeful design, Lansink Dam plays a vital role in maintaining water supply and protecting against potential hazards for residents in the surrounding area.
