Completed in 2018, this earth dam stands at a hydraulic height of 7 feet and spans a length of 1230 feet. With a storage capacity of 13 acre-feet, it serves the primary purpose of mitigating flood risks in the area.
The dam's condition assessment in June 2018 deemed it in satisfactory condition, with a significant hazard potential. Regular inspections are conducted every 5 years to ensure its continued functionality and safety. Despite its critical role in flood risk reduction, the structure has not been modified since its completion and lacks detailed risk management measures.
Water resource and climate enthusiasts interested in the intersection of infrastructure and environmental protection will find Conner Jarvis East Pond to be a valuable case study. Its location, design details, and regulatory oversight offer insights into the complexities of managing water resources in a changing climate. Further research and analysis could uncover opportunities for enhancing the dam's resilience and effectiveness in safeguarding the community from flood events.
