VALENTINE, Neb. (AP) — Nebraska game and wildlife officials say an aquatic habitat project that began this spring at the Valentine National Wildlife Refuge will continue this fall and into 2016.

The project addresses the presence of nuisance common carp in the system.

Control structures, berm improvements, fish barriers and dredging were planned at Watts, Hackberry, Dewey, Whitewater, Clear, Pelican and Willow lakes. Work has progressed and construction has been partially completed at both Watts and Hackberry Lakes.

The Nebraska Game and Parks Commission says work will continue until the first freeze, then resume as weather permits next spring.
