Fish Salvage Declared For Hackberry Lake Posted by Deja Andersen Date: December 31, 2019 2 Views VALENTINE, Neb. (AP) – Nebraska Game and Parks has declared a fish salvage for Hackberry Lake on the Valentine National Wildlife Refuge south of Valentine. Length limits are rescinded during the salvage but daily bag limits are maintained. Fish may be taken only by fishing or archery and salvaged fish cannot be sold or used for stocking into other public or private bodies of water. Hackberry Lake was scheduled to have its existing fish population renovated this year to eliminate common carp on the refuge, but the project wasn’t due to wet conditions and unsuitable water levels.
