The historic Tainter gate from Decorah’s Lower Dam now stands as an outdoor industrial sculpture in Trout Run Park. Originally installed around 1909 to help control water flow for hydropower generation, this Tainter gate is the last of its kind from the dam. Carefully preserved, it serves both as a public work of art and a testament to the engineering innovation that brought electricity to Decorah and its surroundings in the early 20th century. The gate was relocated and permanently displayed in Trout Run Park in May 2021.
