Taff, a gravity dam located in Columbia, Wisconsin, was completed in 1954 and primarily serves the purpose of recreation. With a height of 9.7 feet and a hydraulic height of 6 feet, this structure spans 300 feet in length and has a storage capacity of 70 acre-feet. The dam, situated on the Rocky Run river, covers a surface area of 15 acres and drains a 1.5 square mile area, with a maximum discharge capacity of 372 cubic feet per second.

Despite being categorized with a low hazard potential and fair condition assessment, Taff is considered to have a very high risk level, marked as '1'. The last inspection in July 2015 revealed that the dam is in fair condition, and it undergoes inspections every 10 years. The risk management measures and emergency preparedness plans for Taff are not explicitly outlined in the available data, indicating a potential area for further examination and improvement to ensure the safety and sustainability of this water resource in the face of climate challenges.
