Don Pedro Dike B, located in the picturesque Tuolumne River in California, is a vital piece of infrastructure designed by Bechtel and completed in 1971 for hydroelectric purposes. This earth-type dam stands at a height of 36 feet and stretches 560 feet long, boasting a storage capacity of 2.3 million acre-feet and serving multiple functions including flood risk reduction, irrigation, and recreation. The dam's location in La Grange makes it a key player in the state's water resource management, with state regulatory agencies ensuring its safe operation and maintenance.

Managed by a public utility, Don Pedro Dike B is under the jurisdiction of state and federal agencies, including the Department of Water Resources and the Federal Energy Regulatory Commission. With a high hazard potential and risk assessment rating, the dam's safety and emergency preparedness measures are periodically evaluated, with an Emergency Action Plan last revised in December 2020. The dam's association with other structures in the area highlights its interconnectedness in the region's water management system, with inspections conducted regularly to ensure its structural integrity and functionality.

As a notable feature along the Tuolumne River, Don Pedro Dike B not only contributes to hydroelectric power generation but also supports fish and wildlife habitats, reflecting a harmonious balance between human development and environmental conservation. Its historical significance and ongoing role in water resource management underscore the importance of sustainable infrastructure practices in the face of climate change and increasing water demands. Enthusiasts of water resources and climate resilience will find Don Pedro Dike B a fascinating example of engineering ingenuity and environmental stewardship in action.
