Cross Lake, located in Pine County, Minnesota, is a state-regulated concrete dam constructed in 1938 by the Works Progress Administration (WPA). The dam spans 244 feet in length and stands at a height of 10 feet, with a storage capacity of 14,670 acre-feet and a normal storage of 10,156 acre-feet. The reservoir covers an area of 1,013 acres and is fed by the Snake River, with a drainage area of 968 square miles.

The dam at Cross Lake serves a primary purpose of "Other" and is classified as a low hazard potential structure with a satisfactory condition assessment. The spillway type is uncontrolled, with a maximum discharge capacity of 7,750 cubic feet per second. While the risk assessment for the dam is moderate, with a rating of 3, there are currently no inundation maps prepared, and the last inspection was conducted in July 2013 with a frequency of every 8 years.
