Yerington Bb Dam, located in Lyon County, Nevada, serves as a crucial structure for tailings management along the Walker River. Owned privately, the dam stands at a height of 10 feet with a length of 100 feet, providing a storage capacity of 50 acre-feet. The dam, primarily constructed with earth and stone materials, has a low hazard potential but an unsatisfactory condition assessment, indicating a need for maintenance and improvement.

Despite the dam's low hazard potential, its risk assessment is rated as high due to various factors. The dam lacks a spillway and has limited discharge capacity, which could pose a threat in the event of excess water accumulation. The dam is state-regulated and regularly inspected by the Nevada Division of Water Resources to ensure compliance with safety standards. Emergency action plans and risk management measures may need to be enhanced to address potential safety concerns.

Yerington Bb Dam, situated in the San Francisco District and Congressional District 04 of Nevada, plays a vital role in managing tailings and controlling water flow along the Walker River. With its unique design and purpose, the dam serves as a key infrastructure in the region's water resource management. Ongoing inspections and risk assessments are essential to address any safety issues and ensure the dam's reliability in safeguarding the surrounding areas from potential flooding or water-related emergencies.
