Built in 1886, Jello stands at a height of 20 feet and has a storage capacity of 1,738 acre-feet. The dam spans 1,320 feet in length and is under the regulatory jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC).
Despite its age, Jello is classified as having a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam has not undergone recent inspections or assessments, and there is no Emergency Action Plan (EAP) in place. While Jello serves as a critical infrastructure for flood risk mitigation in the region, the lack of recent evaluations and emergency preparedness measures raises concerns for water resource and climate enthusiasts regarding the safety and effectiveness of the dam in the face of potential natural disasters. Further monitoring and maintenance may be necessary to ensure the long-term resilience of Jello and the surrounding community in Capitol, Montana.
