Hinsdale County and the Town of Lake City faced many challenges while responding to the threat of flooding resulting from abundant snowpack and unprecedented avalanche activity along the Henson Creek and Lake Fork river. Working together, and with the support of the State of Colorado, Bureau of Land Management, National Resource and Conservation Services, and other organizations, Hinsdale County and the Town of Lake City have accomplished a great deal in a short time. The following is a brief sample of their many accomplishments.

Heavy equipment was brought in to remove debris and haul it out of the area to reduce the risk of debris flows. The amount of debris and the corresponding threat has been dramatically reduced.

The Colorado Department of Natural Resources was tasked with evaluating dam safety. With local partners, they determined that the Ute-Ulay dam did not pose a significant risk. However, the Hidden Treasure dam had the potential to become blocked, hold water, and then fail, creating a substantial debris flow. It was recommended that the dam be removed. Contractors began deconstruction, but as the work progressed it was determined that the risk to the community could be mitigated while preserving a portion of the historic Hidden Treasure dam for future generations.

Colorado Department of Transportation evaluated bridges in the affected area. Heavy equipment has been and will continue to be used to remove debris and prevent them from collecting at bridges.

The Town and County devised a public warning system using automated cell phone and landline notifications, and door to door notification by governmental personnel. A warning siren with voice messaging capability has been installed in the Town of Lake City, and a second warning siren will soon be erected to supplement the system.

Over the course of the last six weeks preparedness plans have been developed from the community. Representatives from the Town, County, State and supporting agencies met on June 14, 2019, for a plan rehearsal. Participants ran through a mock exercise to test the alert and warning, evacuation, and re-entry plans. They then provided input. This information will be incorporated into the document.

Critical facilities in Lake City were identified, and the Army Corps of Engineers and others worked to develop plans to protect facilities necessary for the operation of the town, as well as buildings with historical significance. Based on the advice of engineers, an earthen berm was improved along the north bank of the Henson Creek. A second berm made from large sandbags weighing as much as 4 thousand pounds each was constructed south of the Henson Creek to divert flood waters away from homes and businesses. Large sandbags were also used to protect structures between the berms on the south side of Henson Creek. Moreover, approximately 25,000 individual sandbags were filled and distributed throughout the community to homes and businesses.

With these mitigations in place, the threat to Hinsdale County and Lake City is significantly reduced. The Unified Coordination Group sent to assist with the preparedness effort has stood down. Remaining mitigation work will be overseen by local recourses.

Although not anticipated, State of Colorado and emergency management partners stand ready to respond if Hinsdale County needs assistance in the future.
