Mitchell #3, also known as Red Feather Lake, is a private fish and wildlife pond located in Larimer County, Colorado. Built in 1890, this earth dam stands at 11 feet high and spans 140 feet in length, offering a storage capacity of 119 acre-feet. With a primary purpose of supporting fish and wildlife habitats, this reservoir also serves for recreational activities and water supply needs in the area.

Despite its age, Mitchell #3 remains in fair condition with a low hazard potential. However, a high risk assessment level of 2 indicates the need for ongoing monitoring and potential risk management measures to ensure the safety and integrity of the structure. The dam lacks a spillway, but features a spillway width of 30 feet in case of overflow events. The last inspection in September 2013 revealed a satisfactory state, with inspections conducted every 6 years to assess its overall condition.

Located in the scenic surroundings of Columbine Creek, this historic dam plays a vital role in supporting local ecosystems and recreational pursuits. With its picturesque setting and important water resource functions, Mitchell #3 stands as a testament to the enduring legacy of water management efforts in Colorado and highlights the need for sustainable practices to preserve our natural resources for future generations.
