Ramsey is a privately owned dam located in Mapleview, Minnesota, along the Cedar River. Built in 1872, this gravity dam stands at a height of 13 feet and has a length of 138 feet, providing a storage capacity of 340 acre-feet. The primary purpose of the dam is for recreation, with a low hazard potential and poor condition assessment.

Despite being regulated by the Minnesota Department of Natural Resources, Ramsey has not undergone recent inspections, with the last assessment conducted in 2018. The dam poses a low risk, but its poor condition raises concerns for potential hazards. With a drainage area of 182.5 square miles, the dam plays a crucial role in water resource management for the region, highlighting the need for regular maintenance and monitoring to ensure its safety and functionality for recreational activities and environmental conservation efforts.
