Sand Lake, located in Le Sueur, Minnesota, is a state-regulated fish and wildlife pond designed by Ducks Unlimited. Completed in 2013, this 8-foot high dam with a storage capacity of 520 acre-feet serves as a crucial water resource in the region. The dam's primary purpose is to support fish and wildlife habitats, with a surface area of 120 acres and a drainage area of 0.8 square miles.

Managed by the Minnesota Department of Natural Resources (MNDNR EWR), Sand Lake features a low hazard potential and is in satisfactory condition as of the last assessment in April 2014. The dam is equipped with a slide gate outlet and is regularly inspected every 8 years to ensure its structural integrity and safety. With its strategic location on Co. Ditch 5, Sand Lake plays a vital role in providing water resources for the surrounding ecosystem while minimizing the risk of inundation and flood events.

As an essential component of the local water infrastructure, Sand Lake not only supports diverse fish and wildlife populations but also contributes to the overall resilience of the region's climate and water systems. With its efficient design and state-of-the-art management practices, this dam stands as a testament to the collaborative efforts of state agencies, environmental organizations, and local communities in safeguarding water resources for future generations of water and climate enthusiasts.
