Moore, also known as the Thomas Enlargement, is a privately owned dam located in Kremmling, Colorado. Built in 1904 by designer Frank Huntington, this earth dam on Elliott Creek serves the primary purpose of irrigation. Standing at a height of 35 feet and with a length of 280 feet, Moore has a storage capacity of 241 acre-feet and a surface area of 15 acres. The dam is regulated by the Colorado Department of Water Resources and undergoes regular inspections to ensure its structural integrity and safety. With a low hazard potential and fair condition assessment, Moore poses a moderate risk that is managed through appropriate risk management measures.

The design of Moore includes a stone core supported by rock and soil foundations, with an uncontrolled spillway measuring 10 feet in width. Although the dam has not undergone any significant modifications over the years, it is equipped with outlet gates for water release when necessary. The last inspection conducted in October 2018 revealed the dam to be in fair condition, meeting regulatory guidelines and demonstrating a low hazard potential. The risk associated with Moore is considered moderate, with a risk assessment rating of 3, prompting the implementation of proper risk management measures to mitigate any potential hazards. For water resource and climate enthusiasts, Moore presents an interesting case study of a historic dam with a focus on irrigation and regulatory compliance in the state of Colorado.
