About Hopewell Lake Dam
The primary purpose of Hopewell Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by New Mexico Department Of Game And Fish (state). It impounds the Placer Creek near Canon Plaza.
The dam stands 27 feet tall and stretches 340 feet across, creates a reservoir covering 13 acres, has a maximum storage capacity of 170 acre-feet, and collects water from a drainage area of 6 square miles. Completed in 1953, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. The most recent inspection on record was 11/03/2015. That was over 10 years ago.
