North Dakota's Garrison Dam National Fish Hatchery is getting $920,000 in federal stimulus money to invest in pond liners. Officials say it will benefit fishing throughout the Midwest.

The liners help boost fish production in the earthen ponds in several ways, from preventing water leakage to heating the water and eliminating weeds. Manager Rob Holm says plastic liners installed in other ponds in previous years boosted walleye production as much as 18 percent and northern pike production by up to 57 percent.

The hatchery on Lake Sakakawea is the Fish and Wildlife Service's largest walleye hatchery, providing the fish to many western states. Holm says that during a peak demand year when the hatchery is targeting walleye stockings, the liners could make as many as two million additional walleye available.
