The Larimer County Department of Natural Resources shared new boating hours at Horsetooth Reservoir and Carter Lake for the month of May.

According to a news release on the Larimer County Department of Natural Resources website, the opening of Satanka ramp at Horsetooth Reservoir and North ramp at Carter Lake are being delayed due to a seasonal staffing shortage, which has affected the department’s ability to provide the adequate number of Aquatic Nuisance Species (ANS) inspectors needed to cover all boat ramps. As a result, the department has chosen to prioritize the boat ramps that can accommodate the greatest volume of boat launches.
