Polk Dam, located in Lancaster County, Nebraska, was completed in 1936 and serves multiple purposes including fire protection and as a stock or small fish pond. This private earth dam with a stone core stands at a height of 16 feet and spans 450 feet across the TR-Little Salt Creek. With a storage capacity of 61.3 acre-feet and a drainage area of 0.4 square miles, the dam has a low hazard potential and has not been rated for its current condition.

Despite being under state jurisdiction and regulation by the Nebraska Department of Natural Resources, Polk Dam has not been inspected since October 1982. Its emergency action plan status, risk assessment, and management measures are unknown, posing potential concerns for its long-term safety and effectiveness in managing water resources. As an important structure for the local area, it may benefit from updated inspections and risk assessments to ensure its continued functionality and safety for the surrounding community.
