This is no fish tale: There is a 17-pound walleye swimming in North Dakota’s Lake Sakakawea.

State fisheries biologists netted it last spring during the spawning run, weighed it, stripped it of its eggs and returned it to the massive reservoir on the Missouri River.

Given the size of Sakakawea, there’s likely many - relatively speaking - gigantic walleyes calling the lake home. The same biologists, as a matter of fact, netted a 13 1/2-pounder in Sakakawea.

“They are pigs,” said North Dakota Game and Fish Department director Terry Steinwand said. “Absolutely huge.”
