About Hobart
The primary purpose of Hobart is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by City Of Hobart (local government). It impounds the Little Elk Creek near Rocky.
The dam stands 29 feet tall and stretches 1,950 feet across, creates a reservoir covering 347 acres, has a maximum storage capacity of 6,340 acre-feet, and collects water from a drainage area of 55 square miles. Completed in 1933, the structure is well-established, with more than 75 years of service.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 12/23/2021.
