According to Scott Gangl, fisheries management section leader for Game and Fish in Bismarck, the 6- to 8-inch fingerlings were stocked Tuesday at three sites along the Pembina River upstream from Walhalla, North Dakota. The stocking, Gangl said, was done in anticipation of a project to modify an existing low head dam on the Pembina River, near the confluence of the Red River in Pembina, North Dakota, into a rock rapids fishway.
