Comments: Hidden Valley Pond has been stocked with bluegill and produces nice-sized fish from time to time. The City of Cottage Grove sponsors a popular fishing clinic each year in June. The new floating fishing pier was installed in 2014 and makes the deep water in the center of this pond fishable.
