Bass is a privately owned irrigation dam located in Weld County, Colorado, near the city of Platteville. Built in 1896, this earth dam stands at 18 feet in height and stretches 520 feet in length, with a storage capacity of 125 acre-feet. The primary purpose of Bass Dam is to provide water for irrigation in the surrounding area, drawing from the Howlett Gulch-Tr river or stream.

Despite being over a century old, Bass Dam has a low hazard potential and has not been rated for its current condition. The last inspection took place in October 1984, with a scheduled inspection frequency of 6 years. While the risk assessment indicates a high risk level (2), there are no specific risk management measures or emergency action plans in place for this structure. With its historical significance and continued importance for local irrigation, the future maintenance and assessment of Bass Dam will be crucial for water resource and climate enthusiasts in the region.
