Little Pine Lake, located in Aitkin, Minnesota, is a picturesque reservoir formed by a gravity dam constructed in 1937 by the Works Progress Administration (WPA). With a structural height of 10 feet and a dam length of 37 feet, this dam serves primarily for recreational purposes, offering a serene setting for water resource and climate enthusiasts to enjoy. The reservoir has a normal storage capacity of 5,390 acre-feet and covers a surface area of 225 acres, making it a popular spot for fishing, boating, and other outdoor activities.

The dam has a low hazard potential and a fair condition assessment as of the last inspection in 2015. The surrounding area is served by an uncontrolled spillway with a width of 35 feet, allowing for controlled release of water in case of excess inflow. Overall, Little Pine Lake offers a tranquil retreat for visitors to appreciate the beauty of nature while also highlighting the importance of sustainable water resource management.
