RBC | Effective immediately, Rio Blanco County has temporarily closed all equine facilities at the Meeker Fairgrounds and Rangely’s Columbine Park due to the recent outbreak of Equine Herpesvirus-1 (EHV-1) affecting multiple states, including Colorado. This precautionary closure is being implemented to protect the health of local horses, prevent potential transmission, and ensure the safety of upcoming events and facility users.
While the closure is in effect, no new horses or equine activities will be permitted on the grounds. Existing boarders may keep their horses on site or choose to remove them from the facilities; however, once a horse leaves the grounds, it may not return until after reopening.
County staff will use this time to complete enhanced sanitation and biosecurity measures consistent with current recommendations from the Colorado State Veterinarian’s Office.
Anticipated Re-Opening: Dec. 6, 2025
This date is subject to change based on additional guidance or directives from the Colorado State Veterinarian.
We appreciate your understanding and cooperation as we work to ensure the safety of our equine community.
