Grey Reef - North Platte River

When anglers want to catch big fish on big water, we bring them to the Grey Reef. This lower section of the North Platte River provides anglers with the opportunity to catch some very large fish year-round. Despite having access to wadable water, fishing this section from a boat is our preferable way to cover the water effectively.
