Donovan No.1, part of the Robey Group in Wisconsin, is a privately owned Earth dam constructed in 1973 by the USDA NRCS. Its primary purpose is flood risk reduction along the Trimbelle River in Pierce County. The dam stands at a height of 28 feet and spans 490 feet in length, with a storage capacity of 48 acre-feet.

Despite its low hazard potential, the dam has a moderate risk rating due to its condition assessment being unavailable. The emergency action plan (EAP) status is also unknown, indicating potential gaps in preparedness. With a spillway width of 42 feet and a maximum discharge capacity of 150 cubic feet per second, the dam serves as a critical infrastructure for managing water resources in the area.

For water resource and climate enthusiasts, Donovan No.1 presents an intriguing case study in dam management and risk assessment. The collaboration between federal agencies like the USDA NRCS and local authorities is vital for maintaining the structural integrity of dams and ensuring effective flood risk reduction strategies are in place. As climate change continues to impact water systems, understanding the condition and management of dams like Donovan No.1 is crucial for sustainable water resource management in the region.
