Situated in the city of Springvale, this water resource is part of the Stanchfield Creek watershed and is managed by the Minnesota Department of Natural Resources. With a storage capacity of 100 acre-feet and a drainage area of 6.9 square miles, this earth dam structure serves as a critical habitat for local wildlife and contributes to the conservation efforts in the region.

Although the primary purpose of Cranberry WMA South Pool is for fish and wildlife management, the dam also plays a role in flood control and water quality improvement. The dam's spillway is designed as a controlled structure to manage water levels effectively, with a low hazard potential due to its current condition assessment being rated as poor. Despite the risk assessment indicating a very high risk level, the dam's emergency action plan status and risk management measures are currently unlisted, highlighting the need for continued monitoring and maintenance to ensure the safety and functionality of this important water resource.

As a key feature of the local ecosystem, Cranberry WMA South Pool provides valuable habitat for a variety of plant and animal species. With its strategic location within the Stanchfield Creek watershed, this dam serves as a crucial component of the region's water management infrastructure.
