Trego is a captivating hydroelectric dam located on the Namekagon River in Wisconsin, specifically in the city of Riverside. Completed in 1927, this gravity dam stands at 39 feet in height and stretches 625 feet in length, with a storage capacity of 4,700 acre-feet and a maximum discharge of 9,240 cubic feet per second. The dam serves multiple purposes, including hydroelectric power generation and recreation, making it a vital resource for both energy production and outdoor activities in the region.

Managed by the Federal Energy Regulatory Commission, Trego is a significant structure with a hazard potential classified as "Significant" and a risk assessment rating of "Very High (1)." Despite its age, the dam's condition assessment is currently listed as "Not Available," indicating a need for further evaluation. The spillway width of 81 feet and the presence of multiple outlet gates, including slide and tainter gates, contribute to the dam's operational efficiency and safety measures. With its historical significance and ongoing role in water resource management, Trego remains a focal point for water resource and climate enthusiasts interested in sustainable energy solutions and infrastructure resilience.
