Bosch No. 2 is a privately owned dam located in Windsor, Sonoma County, California, along the Tr Windsor Creek. Completed in 1962, this earth dam stands at a height of 55 feet and serves the primary purpose of water supply for irrigation, recreation, and other uses. Managed by the Natural Resources Conservation Service, the dam has a storage capacity of 37 acre-feet and covers a surface area of 2 acres.

Despite its satisfactory condition assessment, Bosch No. 2 poses a high hazard potential, prompting regular inspections by state regulatory agencies to ensure its safety and compliance with permitting requirements. With a history of state jurisdiction, regulation, and enforcement, the dam is equipped with emergency action plans and inundation maps to mitigate risks and protect downstream communities. The last inspection conducted in December 2019 revealed no immediate concerns, but the dam remains under close monitoring due to its critical role in providing water resources to the region.

The presence of Bosch No. 2 highlights the intersection of water resource management and climate resilience in California, where infrastructure plays a vital role in addressing water supply challenges. As a key player in the state's water supply system, this dam serves as a reminder of the ongoing efforts to balance the needs of various stakeholders while ensuring the safety and sustainability of water resources in the face of a changing climate.
