B Lake #2, located in Grundy, Tennessee, is a privately owned Earth dam with a structural height of 15 feet. The dam has a maximum storage capacity of 32 acre-feet and covers a surface area of 4.6 acres with a drainage area of 0.65 square miles. The dam is associated with the TRIBBLACK CREEK and falls under the jurisdiction of the Nashville District of the US Army Corps of Engineers.

Despite its relatively small size, B Lake #2 poses a significant hazard potential, with a moderate risk assessment rating of 3. The dam has not been rated for its condition assessment, and the last inspection was conducted in May 2016. The spillway type is listed as uncontrolled, and there are no outlet gates associated with the structure. Emergency action plans, inundation maps, and risk management measures for the dam are not specified in the available data.

Overall, B Lake #2 serves as an important water resource in the region, providing storage for the surrounding area. However, its significant hazard potential underscores the importance of regular inspections, monitoring, and emergency preparedness to ensure the safety and integrity of the dam and the community downstream. For water resource and climate enthusiasts, B Lake #2 presents a compelling case study in the management and maintenance of small-scale dams in rural settings.
