German #1 is a privately owned irrigation dam located in Fort Lupton, Colorado. Built in 1910, this earth dam stands at a height of 10 feet and stretches 546 feet in length, with a storage capacity of 50 acre-feet. The primary purpose of German #1 is to support irrigation activities in the area, drawing water from the Big Dry Creek-OS. Despite its low hazard potential, the dam is classified as having a high risk level due to its condition assessment being "Not Rated".

This dam is regulated by the Colorado Department of Water Resources (DWR) and undergoes regular inspections, with a frequency of every 6 years. It is equipped with a spillway width of 50 feet, although it currently does not have a spillway type designated. The risk management measures for German #1 are not specified, and there is no Emergency Action Plan (EAP) in place. Despite these gaps in emergency preparedness, German #1 serves as a critical water resource infrastructure for the local agricultural community and contributes to the overall water management system in the region.
