COUNCIL BLUFFS, Iowa – The Iowa Department of Natural Resources continues to focus on clean-up efforts following a fire at the River Valley OHV Park in April, forcing the park to remain closed for a lengthy amount of time. Although the park may look healthy and green, the park will remain closed for safety reasons for an undetermined amount of time. The DNR is working with contractors and the City of Council Bluffs, as well as others, to move forward with clean-up. Any unauthorized use of the park is considered trespassing and is a violation of the law.
