From The Greeley Tribune:
The reservoir is free of ice and the boating dock is installed. All vessels will need to be inspected for aquatic nuisance species before launching. That station will open at 9 a.m. until 5 p.m. Monday through Friday and 8 a.m. until 6 p.m. on the weekends. The water temperature is in the low 40s, which is dangerous for long-term exposure, so boaters should take precautions. Camping is also open and the shower buildings will open in the beginning of April. Bald eagles have also been spotted at the park lately. Contact Jackson Lake State Park for more information at (970) 645-2551.
